I just checked the Virus Bulletin test.....
Look at the awards Avast already have received [url=http://www.avast.com/eng/company/awards/index.html]HERE[/url]

Today a av util fails, tomorrow it is fixed, but you never see them saying. “It failed our last test, but they fixed that so now it is working.”

Very soon there will be a new release of Avast. Many things have been fixed in that one as well as added. See eg the “wishlist for avst 4.5” on this board.

I have the resident scanner set to standard, is this enough protection or should I have this set to high?
That is entirely up to you to decide. It is your system, so you decide how much protection you want.

FYI: Avast Home uses the same engine and vps as the Pro version.
