At school we use Sophos, which has been pretty prompt at notification of new versions of Badtrans, but the technician had a problem downloading the latest update.At home I use McAfee. The update against Badtrans last week didn't pick up the version I got, and the intrusive files were different from those their information described. I was able to download a newer update the day after infection, but the next time I started up, some virus information files were reported as damaged. I've removed and reinstalled the AV software, and downloaded the update again. Also today's anti-Goner update.
Badtrans I got from a known sender. The subject line referred to a matter which I could have expected email about. I have set Outlook Express with no preview pane, but opened it, knowing the sender, and having read that Badtrans used Outlook. HO Hum. The attachment was a 0Kb .txt file. It attempted a download, but the computer reported that it was aborted. Subsequently, every time I logged on to the net, a file (Kernel32.exe) tried to call out, but was stopped by another McAfee program. Which hadn't been able to stop the download in the first place.
I reported back to the sender, who sent another email "Don't open anything from me"!
