I've got Avast Free. Recently it's been tellin g me I've ever-increasing amounts of junk on my hard drive, so I let it scan for them - and it then tells me I have to pay out money for it to clean them. The latest number's 23 gig. Well I MIGHT consider doing that if I totally believed it, but CCleaner can't find them, Bitdefender comes up clean, I don't know ifthis 23gig's for real or if Avast's making it up to get me to payout money so it can pretend it's cleaning something out when there's nothing there.
I just don't know enough!
Please if there's any techiness in the answers, pretend you're talking to an 11 year old on the phone. A geek I am certainly NOT!
