A virus is a malicious software program that can infect your computer, replicate itself, and cause functional problems in your system. It is potentially harmful and can cause a loss of important data, besides corrupting your computer files.

About Viruses

Viruses may spread by attaching themselves in e-mails, instant messages, floppy disks, or pen drives, etc. They tend to corrupt your data, or even delete your important files. Anything and everything present on your hard drive can be erased by a nasty computer virus. These computer viruses are very smart. They tend to visit you, disguised as a greeting card, audio file, video file, or some other morphed entity.

When you are trying to download a software program or music file from the Internet, these computer viruses hide themselves in files, programs, and software, to get downloaded to your personal computer (PC). When you run a program file or boot sector program at boot time, they get activated. The program infected by the virus gets modified, and begins to run the viral code. Soon, it takes control of your PC and begins to replicate and spread. They damage your files, and begin to delete programs and folders in your computer. Some viruses are time activated. They will activate themselves on a specified date, and begin creating havoc on your computer.
