Whatever works for you--I have had AvG for years--and find the scanners to be most helpful. It doesn't sound like your scanner is malfuntioning, unless I am misunderstanding it. Good Luck
I've been using AVG since 1997 and have never had a terrible infection (a couple things slipped through over the years but i was able to get rid of them).
Lately, I've received a few sobers (they seem to come in bunches). I haven't opened any.. I know better than to open odd emails with attachments. But, AVG's email scanner isn't identifying the sobers when its scanning incoming.
Today another one came...with a message in header "AVAST-- Email is infected". Presumably whosever computer sent this out had Avast scan it and Avast put that automatically in the header.
Maybe I don't understand the mechanics of how the AVG email scanner works. Maybe it doesn't scan zip files until you try executing them (Zone Alarm used to catch these zip attachments too-- that hasn't happened in at least a year).
Is Avast better at this? Should I switch?
