Heard of it! Mediocre to good antivirus from Cat Labs. Rebranded as Ultra WinCleaner, which is available at the major retailers. Better alternatives exist!
QuickHeal is an Indish antivirus program. Nothing special about it and so far I have not seen it shinining in any independent tests. So I agree here with JimIT: better alternatives available. wizard
Main, I have also heard of QuickHeal and have read several unflattering reviews of the product on many AV sites. I suggest you google (QuickHeal + Review) to see for yourself. As the others have said, its generally considered a weak AV. If your looking for a Resident front line AV there are tons of better programs. If your looking for a backup try : GAV AVG AVAST all of which are free for personal use. Peace, Jonas
