Download free antivirus from here
Download spybot antispyware from here
Install them both and run a scan with each one of them, if they do not work, it means the viruses had spread too far, in this case you will have to reinstall system.
Start first a complete scan with avg antivirus, it will take several hours.
When finished restart computer and start scan with antispyware.

Good luck.

What is a Virus and how do I know if I have one ?


There are some obvious symptoms that your computer will develop when it gets infected with a virus. But the first thing I have to mention is that if you had a decent antivirus program installed on your computer you would not have a problem. The virus programs now days are fantastic in crushing any chances of a viruses infecting your computer.

What is a virus?
A virus is a small program that gets into your computer undetected in order to cause havoc. This small software program has either been developed because the author enjoys causing disasters for other people or sometimes for monetary gains. Sometimes a virus is packaged in a file that is called a trojan virus. It is disguised as something else, and once it has gained access to your computer it then releases its intent.

How does a virus get onto my computer?
The people that develop these viruses are constantly finding new ways to infiltrate your computer. When one door shuts, another one opens for them. However the most common ways to get a virus on your computer is through the internet. You might download a file that contains a virus, or maybe you might open an email that has one attached to it. Sometimes even visiting a bad website can infect your computer. The worst one of all, however, is when people download illegal cracked software. This software has usually been taken apart and repackaged with a few extras attached. Maybe you download music or videos from the internet. How do you know you are actually downloading the file you intended to. The file may be named to deceive you, and once you open it you will release the virus.

How do I know if I have a virus or not?
If your computer has been infected with a virus you will quickly see odd signs that it exists. Weird things start happening that you cannot explain. Files might move around, odd error messages may appear, programs might start to fail. For example if your virus scanner program stops working then it could have been disabled by a virus. With all this action taking place in the background your computer will also start to run slow and seem like it is busy all the time.
When browsing the internet you might find that you will not able to visits the pages that you choose. You will be redirected to different websites. You computer might also be sending emails to everyone in your contact list without you knowing.

What can a virus do to my computer hardware components?
People think that a virus simply attacks the file systems of your computer, however this is not true. Some viruses are designed to damaged computer hardware components until they are ruined completely.
Many people will argue that a virus only infects software, however all hardware is controlled by various types of software. Infact the entire computer is controlled by BIOS which is software. BIOS controls the temperature of the motherboard. What if a viruses only purpose was to change the temperature control on your motherboard. The motherboard would overheat and fry itself.
In the old days viruses used to be developed to set the read speed of a floppy disk drive to speeds beyond its capability. The Floppy disk drive would overheat and fry from being overworked. Now days Windows Vista has a service called Superfetch that searches your hard drive, finds out what you use the most, and makes it available for you.. If you made a virus to control Superfetch, we could have a serious problem. Most Vista users already have Superfetch disabled on their computer. A virus could enable it, tell it all files are important, keep it searching non stop, and fry your hard drive that way. Now I can here someone saying "yeah right, not with all the security we have around today". Well you should never underestimate these guys who develop viruses. They can work around anything.

What should I do if I get a virus?
If you suspect that your computer has a virus, scan your computer asap with an antivirus program. If you do not have one or yours is not working, download another one, or get a free scan using the free online virus scanners, such as :-
Symantec Security Check :-
http://security.norton.com/sscv6/WelcomePage.asp
or
Kaspersky lab :-
http://www.kaspersky.com/scanforvirus

There is no guarantee that these free scanners will cure your computer but they might just confirm the fact that you actually have a virus.
If you find viruses but cannot remove them you will need to take your computer to a professional before you lose everything. Another option is to format your computer which means you loose all the files on it and re-install a fresh copy of the operating system. You can backup your files first, but please be aware that they might be infected with a virus also.
If you have scanned your computer, found viruses, and successfully deleted them, then now is the time to buy a decent program that will stop this from happening again.
Do not continue to use the computer without taking action because the longer you leave it the further the virus can spread.
What file types commonly contain viruses when you download them?
Lets face it, downloading is a dangerous business, especially when you have important files stored on your computer. Any file you download can contain a virus. My rule for downloading is to ask myself "Do I know and trust this website I am about to download from?"

Here are a few examples of common files that could contain viruses :-
EXE FILE: If you download a program or anything that requires an install file then it will be an .exe file. When you press on it to install to your computer you could be releasing a virus.
ZIP FILE: People download zip files from the internet that contain any other file type and you will not see it's contents until you open it. A zip file might have an exe file in it.
SCR FILE: Free screensavers for your computer. They always have something bad in them. Sometimes adware or viruses.
DOC FILE: A Microsoft word document can contain macros and small scripts that are viruses.

If you haven't got antivirus software installed on your computer, then refer to : http://support.microsoft.com/kb/49500 for Microsoft recommended antivirus softwares.

I can not update my anti virus software. it shows as updated successfully but it does not repair virus, merely it detacts virus


Bro not all updated virus softwares can heal your PC Virus. Like in my PC, the best thing I did to eliminate it is to backup my files and reformat it then install a fresh copy of licensed softwares but not all time. You can also upload a virus to the internet and report it to Virus Fixer companies so that they can study it and fix it. TIme will come after a month or so you may have your computer back to normal. Mostly virus sites were underground. For most protection don't dare visit. :)

Different types of Virus and their effect's.


Different Types of Computer Viruses There are Different Types of Computer Viruses could be classified in (origin, techniques, types of files they infect, where they hide, the kind of damage they cause, the type of operating system or platform they attack) etc. Let us have a look at them…

Computer Virus is a kind of malicious software written intentionally to enter a computer without the user’s permission or knowledge, with an ability to replicate itself, thus continuing to spread. Some viruses do little but replicate others can cause severe harm or adversely effect program and performance of the system. A virus should never be assumed harmless and left on a system. Most common types of viruses are mentioned below:

fb7fa0a.jpg

Resident Viruses
This type of virus is a permanent which dwells in the RAM memory. From there it can overcome and interrupt all of the operations executed by the system: corrupting files and programs that are opened, closed, copied, renamed etc.

Examples include: Randex, CMJ, Meve, and MrKlunky.

Direct Action Viruses
The main purpose of this virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in the AUTOEXEC.BAT file PATH. This batch file is always located in the root directory of the hard disk and carries out certain operations when the computer is booted.

Overwrite Viruses
Virus of this kind is characterized by the fact that it deletes the information contained in the files that it infects, rendering them partially or totally useless once they have been infected.

The only way to clean a file infected by an overwrite virus is to delete the file completely, thus losing the original content.

Examples of this virus include: Way, Trj.Reboot, Trivial.88.D.

Boot Virus
This type of virus affects the boot sector of a floppy or hard disk. This is a crucial part of a disk, in which information on the disk itself is stored together with a program that makes it possible to boot (start) the computer from the disk.

The best way of avoiding boot viruses is to ensure that floppy disks are write-protected and never start your computer with an unknown floppy disk in the disk drive.

Examples of boot viruses include: Polyboot.B, AntiEXE.

Macro Virus
Macro viruses infect files that are created using certain applications or programs that contain macros. These mini-programs make it possible to automate series of operations so that they are performed as a single action, thereby saving the user from having to carry them out one by one.

Examples of macro viruses: Relax, Melissa.A, Bablas, O97M/Y2K.

Directory Virus
Directory viruses change the paths that indicate the location of a file. By executing a program (file with the extension .EXE or .COM) which has been infected by a virus, you are unknowingly running the virus program, while the original file and program have been previously moved by the virus.

Once infected it becomes impossible to locate the original files.

Polymorphic Virus
Polymorphic viruses encrypt or encode themselves in a different way (using different algorithms and encryption keys) every time they infect a system.

This makes it impossible for anti-viruses to find them using string or signature searches (because they are different in each encryption) and also enables them to create a large number of copies of themselves.

Examples include: Elkern, Marburg, Satan Bug, and Tuareg.

File Infectors
This type of virus infects programs or executable files (files with an .EXE or .COM extension). When one of these programs is run, directly or indirectly, the virus is activated, producing the damaging effects it is programmed to carry out. The majority of existing viruses belong to this category, and can be classified depending on the actions that they carry out.

Companion Viruses
Companion viruses can be considered file infector viruses like resident or direct action types. They are known as companion viruses because once they get into the system they "accompany" the other files that already exist. In other words, in order to carry out their infection routines, companion viruses can wait in memory until a program is run (resident viruses) or act immediately by making copies of themselves (direct action viruses).

Some examples include: Stator, Asimov.1539, and Terrax.1069

FAT Virus
The file allocation table or FAT is the part of a disk used to connect information and is a vital part of the normal functioning of the computer.
This type of virus attack can be especially dangerous, by preventing access to certain sections of the disk where important files are stored. Damage caused can result in information losses from individual files or even entire directories.

Worms
A worm is a program very similar to a virus; it has the ability to self-replicate, and can lead to negative effects on your system and most importantly they are detected and eliminated by antiviruses.

Examples of worms include: PSWBugbear.B, Lovgate.F, Trile.C, Sobig.D, Mapson.

Trojans or Trojan Horses
Another unsavory breed of malicious code are Trojans or Trojan horses, which unlike viruses do not reproduce by infecting other files, nor do they self-replicate like worms.

Logic Bombs
They are not considered viruses because they do not replicate. They are not even programs in their own right but rather camouflaged segments of other programs.

Their objective is to destroy data on the computer once certain conditions have been met. Logic bombs go undetected until launched, and the results can be destructive.

COMPUTER HAS A VIRUS


A firewall will just block any access to the Internet incoming and Outgoing, that is not allow by the User, You. Putting a Firewall will assist with not getting any further Viruses, But Not with removing, However if your Mcafee comes with a Firewall and an anti-virus, This would work. You can also Goto Symantec.com or Mcafee and they have free On-line Virus scanners and you can atleast know what your Dealing with. From there Symantec has Virus removal tools for specific viruses. I do however recommend an Anti-virus software, Something like Kaspersky would do you wonders

How to keep your computer virus free


Many people that I have helped with computer viruses had recently purchased new computers which have virus protection included in the software bundle. The problem with these virus protection programs is that the updates are only good for the first year. After that, you must pay a fee to continue to get virus updates.

Many consumers don't realize this and after the year is up, do not renew the membership with the anti-virus company, leaving their computer unprotected from incoming viruses.

So, if you purchased a computer over a year ago, be aware of this problem. You will need to pay the yearly fee to maintain your anti-virus updates or get another anti-virus software available on the market.

There are some anti virus programs that are free or low cost. I have found AVG to provide a good quality free anti-virus program for home users. You can access the download at http://free.avg.com/us-en/download-avg-anti-virus-free.

Also, remember to be aware of emails from senders that you are not familiar with. Also be very careful about opening attachments on any emails. Be sure you know who sent them to you. Even then, if your not sure, verify with the sender that they actually sent this attachment to you before opening it. Email attachments are one of the most common ways of spreading viruses.

So, be careful and happy surfing!
