Tips to Avoid Facebook Viruses and Spam Messages

By With No comments:
Facebook, the biggest social network with 500 million users, provides an interface to hit an unsuspecting crowd with malware and viruses. These viruses aren’t very difficult to detect if you are cautious enough. These Facebook viruses appear on your wall in forms of a bizarre or eye-catching stories and videos and once the user has clicked/liked the link, it is already late. The next step will be getting rid of your Facebook virus which is a time-consuming process. Its better to avoid spam messages and trojan viruses in the first place.

Facebook virus


HOW TO AVOID IT?

1. Think before you Act. Viruses on Facebook are sneaky. The hackers and cyber criminals who want your information know that Facebook users will often click on an interesting post without a moment’s thought. If a post sounds a bit over-the-top like a headline out of a tabloid, this is your first warning sign.

2. Try to avoid Links and videos with Catchy words like “funniest ever,” “most hilarious video on Facebook,” or “you’ve got to see this.” Do some keyword research to see if the post in question comes up in a search engine with information about a current virus or trojan.

3. Check the poster of the Suspicious content. If you receive a message from someone you do not know, this is an obvious red flag. Facebook video viruses also tend to pop up in your news feed or on your wall from friends you haven’t talked to in a while. Unfortunately, it’s likely this friend has already fallen victim to the latest virus on Facebook. After clicking on the story themselves, the message was sent out to all of their friends as well.

4 Avoid messages that have been posted by multiple users as the virus spreads among your friends who were not so cautious. If a link with title such as “Sexiest video ever” shows up all over your feed from all kinds of people (perhaps friends you would not expect to make such a post), this is another warning sign. Similar direct messages are a likely variant of the notorious Facebook Koobface virus which has used this approach in the past.

5. Do not fall for the “typical” money-transfer schemes. Chat messages from friends needing funds will usually sound suspicious. Everything can’t be screened before posting, so money transfer scams and hoax applications still find their way on to Facebook. You should also avoid applications that claim to do a full “Error check” or fix security problems related to your profile.

6. Update your anti-virus software frequently. If you do accidentally click on a post before realizing it is a hoax, do not click on any further links or downloads. If it’s too late and you have already been infected, the Facebook virus removal process may be effortless if you have a good anti-virus program to catch the virus, trojan or other malware early on.

WHAT’S NEXT?

These were few important tips to safeguard your Facebook account but your job isn’t done yet. Once you have detected that the link/post on your Facebook wall is Malicious you should Mark it as SPAM so that the Facebook support will stop it from spreading further and infecting other users.

If you have ever fallen victim of any such Malicious Scheme, please share your experience with all the users in form of comments so that others don’t fall victim

Why My PC Crashes ! Do You Know These Things ?

By With No comments:
There are many reasons for computer to crash ! many of you know few simple tricks to over come of it. But do you really thinks what are you people thinking is the permanent solution for you Computer? Well, Here I'm writing few points which will helps you to solve yourself.


Fatal error: The system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications." You have just been struck by the Blue Screen of Death. Anyone who uses Microsoft Windows will be familiar with this. What can you do? More importantly, how
can you prevent it happening?

  • Hardware conflict
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.
For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself. If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

**** Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it. Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it. Sometimes you may have to find more recent drivers on the internet to make the device function properly. Device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity. To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.
  • Bad Ram
Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing. But a fatal error caused by Ram might be caused by a mismatch of chips. 

For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked. One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged. Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can  be a cause of trouble. EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.
  • BIOS settings
Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up. Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to. A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS 

latency of 3. Newer SDRam has a CAS
latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

                     Everyone Should Know These Computer Short Keys

Microsoft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).
  • Hard disk drives
After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. 

Go to -- Start-Programs-Accessories-System Tools-Disk Defragmenter

This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler. The Task Scheduler should be one of the small icons on the bottom right of the
Windows opening page (the desktop). Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. 

This can be adjusted by going to
**** Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.

Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space. Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. 

Go to-- Start-Programs-Accessories-System Tools-ScanDisk

Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.
  • Fatal OE exceptions and VXD errors
Fatal OE exception errors and VXD errors are often caused by video card problems. These can often be resolved easily by reducing the resolution of the video display. 

Go to-- Start-Settings-Control Panel-Display-Settings

Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate. If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. 

Go to--  Start-Settings-Control Panel-System-Device Manager

Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts. If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse. The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.

Another useful way to resolve video problems is to go to
------ Start-Settings-Control Panel-System-Performance-Graphics
Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).
Look up your video card's manufacturer on the internet and search for the most recent drivers for it.

Google search tips and tricks you need to know

By With 2 comments:
  • Use search operators.
Google does a pretty good job of working out what you're looking for, but the more specific you are the better your results will be.Using operators does just that, so for example enclosing a phrase in quotation marks — "like this" — searches for that specific phrase, adding a minus sign excludes that word (salsa recipe — tomatoes) and using OR gives Google a choice, eg. World Cup location 2014 or 2022.
  •  Search a single site.
You can restrict your search to a single website by using the site: operator, so for example if you wanted to look for interesting techie content on Just2clik you might type android site:just2clik.com.
  •  Get definitions
The define: operator, as you might expect, gives you definitions — so define:search gives you the dictionary definition of search and synonyms such as hunt, look, scout and dig.
  •  Do sums and currency conversions
You probably already know that Google will carry out sums if you type them in the search box — 4*15 gives you 60, 2*2*3*4 gives you 48 and an on-screen calculator and so on — but it can also convert units and currencies. Convert 200 USD to rupee converts dollars to rupees, and you can also convert measurements such as distance, weight and temperature.
  • Get essential info, fast
Google TipsNeed to chase your love interest to the airport? You can quickly check the details on Google Type weather and you'll see the current conditions and a seven-day forecast; add the name of a town to get the weather report from a different location.
Type flight BA1491 to see the status of a flight, time New York to see the local time in that location, sunrise London to see when the sun's coming up or GOOG to see Google's stock information.
  • Search by location
If you type a generic term such as "Italian restaurant", Google will show you results in and around your current location along with a map showing where they are. If you'd rather be more specific, enter the postal code at the end of your query.
  •  Filter your image search
Image filterImage search often throws up seemingly unrelated pictures, so filter your searches. Some terms produce all kinds of search results, so for example an image search for "heather" brings you plants, Heather Graham and Heather from EastEnders.Google will offer to filter those results for you — so for example our search for heather gives us the options "plant", "flower", "eastenders", "scottish" and so on.You can use the Search Tools button to filter by size, colour, type — such as photos of people or illustrations, time and whether you can use the photos without payment.
Remember your operators too: heather — graham produces a screen full of Heathers but no Heather Graham.
  • See sites that aren't online
Google's cache keeps copies of sites it's looked at, so if they're down you can still see them by using the cache: operator — so cache:techradar.com would display TechRadar if for some reason our server wasn't working. The same operator can sometimes catch sneaky "ninja edits", where sites correct appalling, offensive or hilarious mistakes: you'll often find the uncorrected original in the cache.
  •  See what's on
Fancy a film? Movie times Delhi tells you what's on in that particular city, and if you use a specific cinema name such as movie times PVR Saket you'll see what's on in that particular cinema.
  •  Use your voice
If you're using Chrome, Android or the Google iOS app, you can search by voice: press or click on the microphone icon and tell Google what you're looking for.
  •  Check spellings
Not sure how to spell something? Type it into the search box and unless you really mangle it, Google will show you the correct spelling, its definition, and synonyms you might find easier to spell.
  •  Filter your web search
If you click on Search Tools you'll see four filtering options: The country, so for example in India you can search anywhere or limit your results to Indian websites; the date and/or time of publication, ranging from the last hour to the last year; by reading level; and whether Google should use your current location.
  •  Find out what links to what
It's easy to discover who's linking to your site, or to any other page you want to know about: Just use the link: operator, link:techradar.com tells you who's linking to us.
  •  Find similar sites
Here's another handy operator: Related. This one helps you find pages that are similar to one you already know about, so for example related:techradar.com tells you about our sister sites and some of our rivals.
  •  Get nutritional information
Bacon Tofu google tipsWhat a surprise - bacon isn't as healthy as tofu
Some food-related searches will display nutritional information, so looking for chocolate cake will display the calories, nutrients, vitamins and fat in a typical recipe.
Where it gets clever is when you tell Google to compare things, such as compare apples and oranges or compare bacon and tofu.
  •  Search between two numbers
You can restrict Google's search to a specific number range by using two dots, such as 1914..1918 or $250..$350. Annoyingly the financial one doesn't recognise UK pounds: if you type £100..£150 you'll get results in the $100-$150 range instead.
  •  Find specific files
The filetype: operator enables you to search for specific kinds of file, such as Word documents or PDFs. Google indexes most things, so it's just a matter of dropping the dot from the file extension and searching for filetype:xml, filetype:svg or filetype:cs. It's important to note that Google only searches for the file extension, so an XML document that isn't saved with the .xml extension won't show up in a filetype:xml search.
  •  Find apps
You can bring Google's search powers to the world of smartphone apps by clicking More > Apps at the top of the results page. That's particularly handy for Android users, as Android can install apps you select from the Google Play website using your desktop browser.
  •  Customise your search settings
Google enables you to customise your search results in several ways. You can use SafeSearch to filter explicit results (and lock it so the kids can't go in to your search settings and switch it off again), turn Google's instant results off, increase the number of results you get per page and make selected search results open in a new window when you click on them.
  •  Personalise your search settings
If you let it, Google can record your search history and provide access to it on any device. There are several benefits to doing so: You will get more relevant results because Google knows more about you, you'll get better search predictions, and you can search your history for stuff you've looked for previously. Google even organises it into categories such as shopping, news, images and travel. The downside, of course, is that it also records anything dodgy or embarrassing you might have looked for.
  •  Translate from one language to another
Translate - Google tipsNow you can quickly offer flowery insults in any language. Need to translate something in a hurry? Just type translate language A language B (where language A is the language you're translating from and language B the language you're translating to) and you'll see a big friendly translator at the top of the page.
  •  See what others are searching for
Google Trends shows you what others in your country are searching for, with occasionally puzzling results: at the time of writing the UK is interested in Boris Johnson, FIFA 15 and Vitamin D. Google even provides a screensaver that shows you real-time searches - presumably with filtering to screen out the scary stuff.
  •  See Google's best doodles
If you click I'm Feeling Lucky without entering any search criteria Google will take you to its collection of doodles, the customised logos it uses to mark important dates
  •  Uncover Easter eggs
Monster - Google tipsTravel in style, or at least pretend to with Google Maps. If you search for google in 1998 you'll see Google as it was when it first launched. It's not the only Google Easter egg: searching do the harlem shake in YouTube makes the screen dance while do a barrel roll will spin the screen around. In maps, getting directions from Fort Augustus to Urquhart Castle in Scotland enables you to travel by Loch Ness Monster.
  •  Do everything in a single screen
Google's Advanced Search page enables you to use many of its most useful features without having to remember the operators that make them work - so you can enter number ranges, specify the exact words to look for, filter by language, date, reading level, file type or usage rights, restrict your search to a particular site or domain… you get the idea.
