Computer Virus Removal

Computer virus is a piece of computer code that is primarily designed for implanting itself in files or programs to destroy or change the data transmitted on your computer. Typically, a virus can significantly hamper the speed and performance of your PC or just reroute the stored data on other units. Some viruses work really quickly to harm your PC, while others can remain for months before you notice that there is a problem. On the other hand, some viruses can multiply themselves in your computer and utilize disk space or system memory, thus hampering your computer and degrading its performance. Also, there are some viruses that can be extremely serious and remove programs, destroy or corrupt selected files and cause a complete system crash. A virus can open a backdoor for hackers and allow them to browse your computer. Most common types of viruses and methods of

virus detection are mentioned below:

• Resident Viruses
• Boot Viruses
• Program Viruses
• Ways to detect and remove computer viruses

Resident Viruses

This is a permanent kind of virus which gets in the RAM memory of your computer. From there a resident virus can overcome and interrupt all the operations done by your system. Also, it can corrupt all files and programs that are copied, opened or renamed. Example: CMJ, Randex, MrKlunky and Meve.

Boot viruses

This kind of virus affects master boot records in hard disk or infects floppy disk boot records. Example: Stone virus, Disk Killer, Form and Michelangelo.

Program viruses infect executable files like those with extensions .BIN, .COM, .EXE, .OVL, .SYS (device driver) and .DRV (driver). This virus becomes active in memory, replicating itself and infecting files on disk. Example: Cascade, Sunday.

In order to prevent major damage due to virus attacks on your computer, it is imperative to detect and remove viruses as soon as possible. To check if your system has been infected by a virus, notice the speed of your computer. Check if the programs stored on your computer take more time than normal to load.

The next best way to detect viruses is to read error messages you get. When your PC is infected by a virus, you will most probably notice some kind of error message. Generally, error messages appear while you shut down or restart your computer.

Also, checking your computer’s files will assist you to discern if your system has been virus infected. If you suspect virus, you can take a look at your system’s history and notice if any folders or files have recently been added or modified without your consent.

Last but not the least, the most common way to check viruses on your computer is through running a scan using security software. Run a comprehensive virus scan of all folders and files and then delete or quarantine any viruses detected by the computer virus removal program.
