Internet Exploder is so full of security holes it isn't funny. That last to do about IE was everyone had to upgrade to IE 10 because of hacked code Microsoft found in some viruses. Get away from IE NOW!

AdAware is not really an antivirus, and won't block everything.  I'm not experienced with too many of the antivirus programs out there, so others can chime in.  AVG has a free version you can use that's way better than nothing.

Oddly enough Microsoft Security Essentials doesn't completely suck, On Par with AVG but less Bloat (The last 2 or 3 versions have gotten BAD) I use nod32, but somehow my 30 day trial never ends...
I have to use all 3 at work, and if my users upgrade past IE8 and Java 6... boom all their programs stop working. It is crazy town. If it weren't for the security issues I would probably use IE as well. For some reason the Netscape zombie has never appealed to me, and while I liked Chrome... they see everything, and the .gov has their own access into that data. Just scary.Sure they have access to MS as well, but they just aren't as good at aggregating and compiling the data.

Sorry to get off topic.
TL;DR AVG, MS Security Essentials - Good. Macaffee - Bad. Norton - Kill it with fire.

No... not better. In this case the dumber of two evils?  I don't Mind IE, it isn't nearly as bad as it was, and isn't truly deserving of all the guff it gets. Except on security stuff... like setting out to sea in a sieve.
