A few weeks ago I received a Norton 360 warning about Trojan.gen.2 and an advisory that all was well with the attack having been blocked. Subsequently everything started running slowly. I ran the following to try to clean it up:
Norton 360 (including NPE)
Malwarebytes Anti Malware (free version)
Microsoft removal tool
Spybot search and destroy
I changed all my passwords etc using a clean computer
Then ran JRT & Rogue Killer which I had never heard of on advice of a friend.
Everything then seemed to have a clean bill of health and speed certainly improved.
This morning I received a phone call, purportedly from my ISP, advising me that I had downloaded some malware and offering to remove it free of charge - all I had to do was give them remote access. I ended the call and checked with the ISP who confirmed what I already knew.
My concern is that the caller had information he used to try to establish his bona-fides that, quite honestly, he should not have known.
I am concerned that there is something lurking there that is not getting picked up.
My original thought was to reinstall Windows but this is something I'd like to avoid it at all possible and I'm a little concerned that, since the recovery software is bundled on the same physical drive, that this could be infected as well.
Any help gratefully received.
