Threatfire False Positive??

[DavidR]

It does answer the question because if you read the original posters question.

When I did a scan with Avast it alerted that Tfmisc.dll located in C:\Program Files\ThreatFire\TFMisc.dll is a Trojan known as win32:knlone-rx but this file belongs to Threatfire which is a safe program from Pctools.
I also uploaded the file to virus-total and only Avast detected it as win32:Knlone-rx and Prev1 as a suspicious file.So, can I resolve this problem.

I highlighted the relevant part where the check on VT gives a pretty strong indication that this is a false positive.

VirusTotal uses the windows version of avast (more packers supported) and there are currently 32 different scanners. So excluding avast the only other scanner that detected anything said it was suspicious, which would tend to indicate Heuristic detection that are prone to mis-detection.
