Hello mcmillen. I’ve been following your problems with Avast 4.5. I, as well, have had no end of problems with my new Avast. I have reverted back to V.1 until they have the problems resolved. You can PM your e-mail addy and I will send it along to you, if you wish. It’s 7 megs, so you’ll need broadband, probably. Let me know.
