I have a very similar problem, same exact characteristics mentioned
below but under a different name. I'm dealing with a virus called
backdoor.trojan and I have pin pointed the file it's associated with as
wdma.dll. Tried everything John posted below too but still to no avail.
Please I'll really appreciate if someone could help. Thanks
