5 Tips to keep your computer virus-free

1. Scan floppies before using them - This is always important, but especially if you are using the disk to carry information between one computer and another.
   
2. Don't download programs from the Web - Unreliable sources such as Internet newsgroups or Web sites that you haven't heard of may be willing providers of viruses for your computer. Avoid downloading files you can't be sure are safe.
   
3. Don't automatically open attachments - It's always better to err on the side of safety. If you're unsure about an attachment, delete it. Especially if it's from a source you don't recognize. If there are tempting animations on a site that look highly unprofessional, don't download them.
4. Install reliable anti-virus software - Anti-virus software scans files regularly for unusual changes in file size, programs that match the software's database of known viruses, suspicious email attachments, and other warning signs. It's the most important step you can take towards keeping your computer clean of viruses.
   
5. Buy antivirus software from an authorised reseller - This entitles you to the necessary support and software upgrades offered by the company.
