I have just installed Microsoft Office 2007 on my computer at work. What is a good anti-spyware/virus program?

I have a network at work. 2 computers are shared via the Linksys. Both of the computers are wireless. The Microsoft Office 2007 software has been installed on both. I would like to know what is a good virus protection/spyware program i should purchase/try. Please help. Are the free ones just as good as the one i have to purchase? what should i do??

My computers are running the Windows XP.

Talk about idiot. Nice answer. guess that's all his vocabulary. Anyways.
Spysweeper is the way to go.
The best software you should get is Spysweeper with Anti-virus, this software is too good and gets better everyday. This is ELITE software. It blocks over 433,000 definition threats, which contain several fringerprints with each(you can do the math). No other software can compete with that or come close for that matter. It catches everything and has active shields. I've used them all and it is 2nd to none.
Don't waste your time with AVG, spybot, ad aware, CA, spyhunter, mcafee, superantispyware, avast, panda, kaspersky, windows defender or anything of the sort. Stay away from anything that is FREE when it comes to spyware and antivirus. There is a reason why they are free. They are NOT good. I even guaranDAMNtee my answers and will help through IM if needed.

Hmm... people don't seem to like your answer. Strange. Report It

idiot

Edit: To Undertaker_COTN: Why should I use an extensive vocabulary when a simple word will sum up everything? Unlike you, I don't feel the need to flaunt a large answer in order to display my superiority. I called him an idiot, and now the same statement can be applied to you, because he could have answered his question with a google search. In addition to that, Microsoft Office has nothing what-so-ever to do with his question. While I doubt that you will return to this question at any time before you vote for your own answer, I just felt that your comment towards me needed to be addressed. Even if you did return you wouldn't see my answer as you were so insecure with your own answer that you degraded all of the previous answers by marking them with the feared "thumbs-down". At any rate, have a good day.

Edit: And look, I was able to answer without profanity. You're right, I must not have a very impressive vocabulary as I can't use the "big" words you can. I should go read a dictionary, followed by a thesaurus, in order to improve myself.

Whats microsoft office got to do with it?
