I have used previous versions with mixed fortunes. In the old days it did tend to err on the false positive side. It also tended to miss some "non-viral" malware.

That said, this is a new version and it is in beta test . I would not be inclined to recommend it to people who did not have a fair idea of what they were doing.

My advice would be to wait for a stable release version?................. unless, of course you want to do some beta testing

At the moment, I would still be inclined to use Avast! or AVG for people who are not IT types.
