A few free online security programs that work, and are safe.

The Title says it all,and if you have any questions about any of them just ask.

Ad-Aware SE

not my favorite but it's OK.

Spy bot search and destroy

decent Program but it is a resource pig.

Superantispyware.com

http://www.superantispyware.com/?tag=GOOGLE-SUPERANTISPYWARE

I would have to say for spyware this is my favorite.

AVG Free

Excellent free software, It works and is not to hard on system resources
Avast
http://www.avast.com/en-ca/index

Avast is OK too but it is too noisy for me

CCleaner

http://www.piriform.com/ccleaner/download

Now for routine cleaning and maintenance, get this its a must...

Hijackthis

http://download.cnet.com/Trend-Micro-HijackThis/3000-8022_4-10227353.html

I recommend this for more advanced users, it can cause damage to important folders if used wrong.

I will post more later, I need to get to sleep here soon, I hope these help some of you out.
