Computer Security tips:

Use an Anti-Virus program.

I recommend is Avast free.

Use a firewall program.

I recommend Comodo firewall which is free.

Use Anti-Spyware software.

Spybot is a good free Anti-Spyware program.

Update your security software, OS and scan your computer weekly for viruses, spyware, and adware.

Download and buy software and files from trusted sites you know are virus free like download.com or sourceforge.net .

Read the reviews before you download something to see if the software is any good or is bad.
