stick to avast. Avast it increasing its feature set in a regular basis. But the one thing they still lack is the repair file feature. Till now i have cleaned off 10,000 viruses of my PC or friend but not even once had repair worked.
@ Sam - even I've not seen any AV repaired even a single file ( specially executable files ) successfully and ~10K virus infected files or 10k viruses of different types - you should be rewarded as the Most Experienced Virus Cleaner of the TDF forum - we should really think about starting a MEVC award
quick heal used to do it
and its not different virus rather most are the same type. Some of my friends never use antivirus. their theory is antivirus slows down system and games. So whenever their system stops responding or breaks down cause of excessive infection, i get called (cause i always have latest version or updates) and end up install avast/avira and the virus kicking starts
all of the Avast better have a look at this
