One of my relatives is using Prevx on their netbook at my reccomendation. Their last scan showed that acs.exe is a malware and should be removed. Luckily before they removed it they gave me a call, and I realised that acs.exe is a component related to their atheros wifi card. Obviously going through the save a scan log and send it to X was a bit much to do over the phone whilst driving so I told them to right click and mark the file as a false positive. My question is, if a file is marked as a false positive, is any kind of indication sent back to PX so that it can be verified and removed if indeed found to be false, or is it just a local override?
