clean up procedures and FREEWARE

I just upgraded my Dell 8200 Dell from ME to XP and I'm trying to clean things up. I 'm using FREE adaware, spybot S&D, AVG, ZONEALARM.

I ran (CA) PestScan and I have SearchSquire-Hijackr, unknown dialer, toprebates, peopleonpage-hijkr, targetsoft.winhost32, IBIStoolbar-hijkr, HuntBar-hijkr, networkEssentials-hijkr, and a few others.

Do I have to research each one of these of these and remove them manually as CA or Symantyc suggest or is there some FREE removal tools or some more FREEware I could use along with what I already have that would work?
I know that's the price you pay for using Freeware

 

For the virus/trojan infections, I would suggest running TrendMicro's Online Virus Scan to remove the infections.

For the spyware infections I would stick with Ad-Aware SE, SpyBot S&D, and SpySweeper.
