1. Stop and think before opening any attachment you receive.
If you don’t know the sender, don’t open the attachment – just delete it. It doesn’t matter if the subject promises you’ll see Britney Spears dancing nude on the kitchen table, just delete it.
Most of the devastating worms and viruses of recent times were distributed via email. These viruses feed on the curiosity and also the ignorance of a huge number of email users. People will get an email from fakename@weirdsuspiciousdomain and they’ll just open whatever file is attached to it.
If the email is from someone you know, always scan any attachments first before downloading or opening them.
If every email user in the world followed these simple guidelines the distribution of viruses via email will grind to a halt.
2. Protect yourself

Good virus protection doesn’t need to cost you a fortune. You can get excellent free anti-virus software on the Internet. Even the professional version of their software is very affordable.
For spyware protection, you can get it for free on the Internet as well.
As for a firewall, Windows XP ships with a decent enough firewall. Just make sure it is always enabled. Alternatively you can visit a site like http://www.download.com and search for Zone Alarm, which has an excellent free version.
The most important thing to keep in mind is that you need to keep your anti-virus software up to date. It is recommended that you update your anti-virus and anti-spyware software at least once a week. An anti-virus program that uses definitions that are months old is just about useless.
3. Watch out what you download
Spyware is embedded in a lot of software on the Internet – especially those related to ripping, converting and playing music and videos. That free MP3 player or DVD Ripper you just downloaded may have installed a bunch of harmful spyware without you even knowing about it.
4. Keep yourself informed
