I've been reading lots over the past two days but not found quite what I am looking for - or if I have, I don't realise it.
Here's what happened.
I downloaded utorrent, tried to download a few files through it and then got infected. it was the antimalware one, plus a couple of others, the sheild poppoed up on my tray too.
I found a post that seemed to describe my isses and how to fix. I basically followed the instructions without running any OTL codes.
here's a link to the post.link to original post
I believe it had disabled my corporate edition of Symantec. I ran Trenmicro house call and it also didn't detect anything.
I ran combofix and it detected a bunch of things and sorted the antimalware in the icon tray, however, I was still getting constant pop ups from my anyvirus saying that an email could not be sent, so my machine is constantly trying to send out malicious emails/spam.
I then went into safe mode, ran combo fix again, then ran Eset online scan, again, it detected a few bits and pieces and removed them.
I've run the virus software a few times since yesterday and it shows clean, however I still continue to get the Symantec preventing the spam emails from being sent.
I guess now I am asking for help - oh, and by the way, 20 years in computers - my first virus!
