What Is Exactly Computer Virus

Friends ,Before you begin the battle against these kinds of computer viruses it's recommended that you get to know your enemy first . If you can understand your enemy you can then beat him .
Viruses feat neatly into the malicious software type of computer software - malware is just a small type of malicious software program .
It's always funny to watch many Hollywood hacker picture and to see a virus on a pc monitor with a laughing skull or a voice message about how you've just been hacked . That's so much crap ! Real viruses - the really good ones - stay hidden . The arrive in e-mail attachments or hidden other programs and they stay hidden until it's time to attack . Computer viruses are very much like human viruses - they need someplace to live first and reproduce and then they appear when the time is right .
Once the virus is activated and has spread around your computer system then the damage phase will begin . Most viruses are written to activate on a specific trigger - a time , date or once the virus has infected x number of files . Once the trigger point is reached the virus then delivers its payload to your system.
 This might be just annoying messages or it might trash your entire operating system and leave you staring at a blank screen . Once you've had this happen to you once it never happens again believe me .
Worms are another "type" of computer virus but they're just a little bit different . A worm is able to reproduce itself and move around networks without using other programs or software as hosts .
Worms are usually more damaging to networks of computers than to individual computers . Because they self-reproduce they can cause damage by overloading network resources . This overload can cause slowdowns on the network by taking up a lot of bandwidth on the network itself . Like viruses , worms are sometimes designed to carry a payload . This is done by using a 'backdoor' on the target system .
Back in the day computer viruses were spread mostly on floppy disks and this was bad enough . Then the Internet arrived and proved to be massively popular with everyone ( how wrong could Bill Gates be ? ) and viruses started spreading even more quickly by e-mail and downloaded files . A virus that used to take weeks or months to travel around the world was now able to infect computers all over the

The Best Adware N Spyware Removal Software

Many people have difficulties finding the perfect adware/spyware removal program that is powerful while not expensive. You have probably seen all those software packages that claim to offer free scan and free download, completely free adware/spyware removal software, however, are very hard to find.

You can expect two kinds of programs. One might let you try the software for a few days before you must buy an expensive version of the software. A few days is usually not enough to find if you are comfortable with your adware/spyware removal program or not. Another disadvantage with this kind of software is that when you purchase an expensive adware/spyware removal product, you will most likely stick to that program even if the program becomes outdated or a better program is offered on the market.

In other cases, you can use their really free adware/spyware removal programs for as long as you wish, but it only offers very limited protection from adware and spyware. You are then forced to buy a better, but pricey, version of the software. Sometimes it is actually a really great free adware/spyware removal program that you are offered, but the updates cost quite a lot of money. Since all adware removal programs need to be updated frequently to stay modern, this can be very costly in the end.

Be vigilant when you see a website that claims to offer a really free adware/spyware removal product. There are a lot of dishonest sites offering fake adware removal programs. These fake programs are promoted vigorously on the Internet, and many computer users are lured into installing what they think is protective. But what really happens is that they secretly install adware, spyware and other types of malware in your computer and force you to buy their so called adware/spyware removal products later.

Remove Spyware, Viruses, And Rootkits

Even careful PC users can fall prey to the sticky fingers of evil malware. Loading an innocent looking file from a USB stick, clicking the wrong link in search results, cancelling a suspect alert box – all these actions could mark the beginning of a malware infection.
And let’s not be coy – if your internet activities include downloading torrents or using pirated software, you’re even more likely to fall prey to worms, spyware and trojans.
In some ways, discovering that your computer is virally infected is worse than realising that it’s been compromised mechanically. You could have lost valuable data, your backups could be infected, and the machine may need a wipe and full reinstall of Windows.
But there are things you can try first, and there’s a workflow you can use to clean your PC and recover your files. We’ll take you through it.
Signs of malware
Some malware infections are easy to spot – others less so. There are many infections we might call ‘scareware’ in the wild. These are trojans that malicious websites trick you into downloading by popping up an alert claiming that your PC is already infected with malware. Once on your machine, these annoying infections will replicate themselves in several places, popping up further messages, browser windows and alerts.
Infections like this are easy to identify. Unusual new toolbars, shortcuts on your desktop to software you don’t remember installing and your browser switching its homepage are all classic symptoms. Other, less obvious signs might include increased use of your broadband download allowance, router lights showing activity when there shouldn’t be any, your browser popping up unexpected windows and even unexplained rebooting.
Some malware behaviours are just plain odd, like a mouse pointer that flips orientation. Whatever the signs, the cure is the same: removal of the malicious code.
Stabilise your system
The first thing to do is to attempt to stabilise your system as much as possible. This might prove difficult if your machine is popping up windows and alerts every second, so the first trick to try is to reboot in safe mode.
Restart your computer and press [F8] during startup (press it twice if you’re given a choice of operating system first). Choose ‘Safe mode’ from the Advanced Boot Options screen. This will launch Windows with all startup programs disabled, and limited hardware drivers loaded. You’ll also be without any networking functionality, which is essential for stopping spyware programs phoning home or pulling data from pop-up windows.
Type msconfig in the Start Menu search box and launch the program. Click the ‘Startup’ tab and untick all but the essentials – or simply choose ‘Disable all’. Click ‘Apply’ to confirm, then go to the ‘Boot’ tab. Check ‘Make all boot settings permanent’.
go to the Control Panel and choose ‘Add/Remove Programs’. Remove any non-essential programs, especially toolbars and browser add-ons. In some cases, these actions may be enough to stop malicious code from loading at startup.
Now you need to remove temporary files. Empty all browser caches, and all files in the following folders if present:
C:\Windows\Temp\
C:\Temp\
C:\Documents and Settings\yourusername\Local Settings\Temp\
C:\Documents and Settings\yourusername\My Documents\Downloads\
You can get your browser to wipe temporary internet files too. Go to ‘Tools | Options | Clear browsing data’ in Chrome, or go to ‘Tools | Internet options’ in Internet Explorer, then choose ‘Delete’ under ‘Browsing History’. Tick every box and click ‘OK’.
