Installing anti-virus software will not help if you do not keep it up to date. Make a habit of downloading new virus definitions at least once a week.

When downloading files and attachments, always scan them before you open them. The same rule of thumb applies to files you copy from floppy disks or other removable media.

After installing anti-virus software, it is important to scan your system on a regular basis. Most products will allow you to schedule a scan so it is performed automatically.

Examples of untrusted sites might be chat rooms, instant messengers, personal homepages and news groups. Try to find the homepage of the company that created the f ile to download a trusted version.

Spend a few minutes every week making yourself familiar with the new virus threats that are released. Your antivirus vendor should post new advisories to it’s homepage on a daily basis.

Many viruses and worms exploit holes in your operating system to do their damage. Applying patches and updates as they are released will help minimize your risk of being infected.
