Answer 1

Assuming you are running XP, and this is the little shield in the task bar.

There are a couple, the best free one, in my opinion, is AVG, do a search for it and download the free hom edition.

Answer 2

These are all good free places to go for virus and or spyware protection, removal and advice

Answer 3

virus proctect for free avg 7.5 free personal edition at www.grissoft.com download install and then update
Next you'll need anti spyware...the best free one I've found is spybot search and destroy found at www.spybot.com or put spybot search and destroy in a search engine...download install, update
Then you'll need free adware remover...SE Personal Free edition is my favorite at www.lavasoft.com download, install update then run AVG first then the adware and spyware...
