Protecting Against Viruses A virus is a program written with malicious intent for the purpose of creating havoc in a computer system. It attaches itself to executable files or boot sectors, so it can replicate and spread. Some viruses may only cause your system to beep or display messages or images on the screen. Other viruses are highly destructive and corrupt or erase the contents of your files or diskettes. To be safe, never assume any virus is harmless. Viruses spread through direct contact with executable programs or boot sectors. Diskettes used in a contaminated system get a virus and transfer the virus when used in another system. A virus can also spread through programs downloaded from bulletin boards or the Internet. To protect your system against viruses • Obtain an antivirus program and scan your system regularly. • Make backup copies of all files and write-protect the diskettes. • Obtain all software from reputable sources and always scan new software for any viruses before installing files. If you suspect your system has been infected, find and remove the viruses immediately using an antivirus program. Next, turn your system off and leave it off for at least 15 seconds before turning it back on. This is the only way to ensure the virus does not remain in your system RAM.
