Hi Guys
You have all got me really worried now.
I did a search for shimgapi.dll and found nothing.
As I said at the beginning I am new to this and did not realise that the trojans could replicate or that they could be associated with each other.
As well as the ._file[1].exe which is discussed on a separate thread I now realise that I should have mentioned that there is another file in the chest which was picked up at the same time as ._file[1].exe.
This file is called A0177674.exe and was found in my system restore folders. Avast identifies it as win32:trojan-gen (other). I do use Limewire and I did download a file that contained a generic trojan that AVG8 said it caught but AVG did not report the two files that Avast has found so I wonder if it caught everything it should have.
Does this help
I have not cleared anything out of the chest yet but I am presuming that while they are in the chest they cannot continue to function -is this correct?
Ltangelic re your post on the other thread Avast does not offer me a quarantine facility -simply delete the file or ignore it. However it returns the next time I boot up and even a boot scan does not identify anything.
