Computer Viruses

In November of 1987, the Lehigh virus was discovered at Lehigh University in the U.S. It was the first "memory resident file infector". A file-infecting virus attacks executable files. It gets control when the file is opened. The Lehigh virus attacked a file called COMMAND.COM. When the file was run (usually by booting from an infected disk), the virus stayed in the resident memory. Viruses can be stopped by good internet security software and personal firewall software.
