Today early morning I manually updated my avast free home edition ( I always update manually) to 090921-0 VPS. Later in the afternoon I manually checked again to see if there is a new VPS and avast downloaded huge (20mb I think) VPS update, usually updates are lot smaller. Anyway the weird thing that now my virus database seems to switched back to yesterday’s 090920-0 and if I try to update I get the message that Avast is up to date with 090921-0 VPS.
I opened avast and clicked on “Update Virus Database” (Vista skin) and it downloaded around 20 000 000 bytes file as I said. I knew it was weird when I saw how big the file is but I thought that maybe it had some Avast update or that it had something to do with Avast 5. Anyway I’ll see how updating goes when a new update is realeased.
Can you try to repair your installation?
Go to Control Panel > Add/Remove programs > avast! antivirus > Remove. Then choose Repair function in the popup window (Repair).
ZedDJ, send me file setup.log from avast4\setup folder (possibly compressed to my email).
Do you connect to internet through a proxy server, or do you use some internet caching software?
