Security Software?

I tend to use ESET Smart Security 4, its never let me down, excellently lightweight for gaming too.

Hello Goofy Goof;

The editors @ C/Net have some recommendations:
Security Starter Kit
Windows Starter Kit
Utilities Starter Kit

MICROSOFT SECURITY ESSENTIALS is the best! it does a good job and doesnt slow down your computer. And its free. And if your not running Vista or 7, which include Windows Defender, get that too!

Personally, all the security software on my pc is free as well. I use AVG antivirus combined with PC tools firewall plus. Between those, I have relatively few issues.
