I have had my share of infections and Anti viruses.
Basically I have found a couple of free AV that are worth checking out. McAfee and Norton are not really that good for me since they are too resource hogs. Kaspersky is good but they give my the chills when the banshee shouts like hell. Avast and Nod 32 are ok. AVG, they used to be very very good but now they are not picking up that many viruses.
Right now I am running two, Panda's Cloud Antivirus ( Its fast, I do not need to update it and I'm always online )and Malwarebytes ( I use this for realtime protection ( Installs in Minutes and only uses a tiny bit of your resource )
I was impressed with Malwarebytes on how fast it handles things. The only thing that Malwarebytes is not good at are rootkits, that is where I use Cloud AV for.
And if your in really really deep I would suggest you download and use the following to clean up your system.
DrWeb Cure It ( Its slower but it really cleans and ensures your safe )
SuperAntiSpyware ( Sounds like a rouge AV but its not. Its not even an AV, it only removes spyware. Its better that Adaware and Spybot Search and destroy )
For Advance users using XP, I would advise ComboFix.
Cheers.
