What's the key to preventing viruses? Caution first and software second.
Computer viruses are often spread by email and web-based downloads, sometimes disguised as games, images, or ordinary-looking documents that when opened can damage your computer files or operating system. To guard your computer, we suggest the following steps:
- Do not download any files from strangers. Do not open any files attached to an email from an unknown, suspicious or untrustworthy source.
- Do not open any files attached to an email unless you know what it is, even if it appears to come from a friend or someone you know. Some viruses can replicate themselves and spread through email. Better be safe than sorry and confirm they really sent it.
- Do not open any files attached to an email if the subject line is questionable or unexpected. If you feel you must, always save the file to your hard drive first.
- Back up your files on a regular basis. If a virus destroys your files, at least you can replace them with your back-up copy. You should store your backup copy in a separate location from your work files, preferably one that is not on your computer.
- Keep your system software up-to-date. Many viruses can be rendered powerless by downloading updates for your operating system. Windows users can do this by visiting Microsoft's Windows Update site. Macintosh users can use their built-in "Mac OS Software Update" tool, or visit the Apple Featured Software page.
- Install (and keep up-to-date) an anti-virus software package. There are many excellent anti-virus programs, including AVG Antivirus, McAfee VirusScan, and Norton AntiVirus.
