Hi i wonder if anyone can help me, i keep getting avg telling me that it has detected the above threat. I have tried scanning computer with AVG, Housecall and a couple of others that claim to be able to detect and remove trojan horses. I have had no joy with getting rid of it despite "healing", moving to virus vault and emptying virus vault. I have also tried system restore but computer is "unable to do system restore" despite trying 2 different dates. I am not a computer buff and am really struggling as i dont know what else to do to get rid of it, i dont really want to format hard drive as im unsure of how to do that. Help please!!!!!!
Thanks in anticipation

My in-law PCs just started having a similar problem yesterday. Also saying that install files on the HP CDROM are infected. My guess is that a signature update to AVG is wrongly identifying some HP printer software as containing this Trojan.

Probably need to speak to AVG to see if they agree.

actually that does seem familiar - im sure i noticed hp digital imaging in a couple of the lines containing the trojan - phew that would be a big relief if thats what it is, thank you

I too have had this supposed 'trojan', and I am curious at why this is - I cannot heal or move it to the vault with AVG, as it tells me that 'the operation was interrupted by the user'. Tell me, do you have a HP Deskjet D1600 printer? I have a feeling that might be the case.

Have you tried scanning with Malware Bytes to see if it's detected anything?. AVG has a big problem with false positives (When an Anti-Virus/Anti-Spyware program detects a file as being malicious but infact it is not). I would recommend switching to Avast!, or even Kaspersky.

The problem seems to have stopped now - but my printer is a HP Deskjet F2480 which is fairly new. I had tried a few anti virus (one of which was malware bytes) but this and another one (cant remember the name sorry!) said that it had found nothing. Good luck i hope you find that the problem goes away for you too!!
