  11. Basic Virus defense • Don’t open files that you are not expecting • Many viruses automatically send files without the e-mail account owner’s knowledge. • Ask the sender to confirm unexpected files. • Suspect messages that appear more than once in your Inbox • You may receive the same e-mail from a virus repeatedly. www.compvirus.co.cc

  12. Basic Virus defense • Learn file extensions • Your computer will display both an icon and a file extension for files you receive. Open only file extensions you know are safe. • The following file types should never be opened: • .EXE • .PIF • .BAT • .VBS • .COM www.compvirus.co.cc

It is good to be aware of viruses and other malware and it is cheaper to protect you environment from them rather then being sorry. There might be a virus in your computer if it starts acting differently. There is no reason to panic if the computer virus is found • It is good to be a little suspicious of malware when you surf in the Internet and download files. Some files that look interesting might hide a malware • Virus’s mission is to hop from program to other and this can happen via USB disks, Internet FTP sites, newsgroups and via email attachments.
