Hi

Is there any free antivirus available on the net,which is powerful and light on the system ?.I am using the free AVG 7.5 and found it to be an excellent piece of antivirus but the damn
thing is expiring in 2 days and needs to be upgraded to 8.00
which costs a damn $54 for a year of license.
Long story short...is there any free avirus out there with good protection ?

Thanks
