I currently use Comodo Anti-Virus and Firewall. However, I wouldn't say that it is better than AVG. Preventing infection is not just about having a good anti-virus, your internet surfing habits play a big part.
Have a read of this: http://www.bleepingcomputer.com/forums/t/44675/how-did-i-get-infected/
Malwarebytes and SUPERAntiSpyware are both good applications and it certainly wouldn't hurt to run a scan with them from time to time.
If you’re clean, you should create a new Restore Point
to prevent possible re-infection from an old one.
> System Tools
and click System Restore
. Choose the radio button marked Create a Restore Point
on the first screen then click Next
. Give the Restore Point a name and then click Create
. Then use Disk Cleanup
to remove all but the most recently created Restore Point. Go Start
and type: "Cleanmgr" (without the quotes). Click Ok
> More Options
tab > Clean Up
in the System Restore section to remove all previous restore points except the newly created one.
Also, go Start
> Control Panel
and double-click Add or Remove Programs
. Post back and report any Java
entries that you have.
