Did that and it came up clean across the board.Copy the exact filename that Avast detected, go to virustotal.com website and let the database search it. Could be a false positive.
I have seen this too now a few times in the last couple days, the vBulletin is redirecting to http:// myfilestore.com/ download.php ?id=5636a6d4 (spaces put in to make it unclickable) every now and then. Google search on it seems to indicate various vBulletin exploits have been patched in the past, perhaps satelliteguys.us is being attacked. I am accessing the site via a yahoo bookmark. Maybe Scott needs to apply a new security patch?
