below was posted by excile in the gen section

The fact that only registry entries were found, and no files were detected. In many cases (though certainly not always) when only registry entries are detected and no files are detected, it can indicate a false positive.

Though I may be wrong in this case, following the directions above will determine which is the case because the researchers will investigate what caused the detection, be it a false positive or an actual infection.

also my comp has hardly been on since i did my last scan which was clear and kaspersky didnt pick anything up which is the IV i use

Yes, it can indicate a false positive but there are also many occasions where files were previously Antivirus programs. To the best of my knowledge, most if not all of the AVs will not clean the registry of the entries that malware creates. Anyway, this registry entry is created mainly by assorted adware. If you do not wish for mbam to continue detecting it, you can select to have the app ignore the entry in subsequent scans.

Apologies. I should have spoken clearer. The entry which mbam have detected is a registry key created by adware.

Since no files but only a registry entry was detected, it has to be assumed that whatever malware file that created the registry entry has previously got removed/eliminated by some other antivirus program. Unlike mbam, antivirus programs will not detect nor offer to remove registry keys created by malware. Hence the current detection.

Should you wish to not have mbam delete the entry, you can have mbam.exe ignore the entry. Please refer to the image below

Right click the entry in question. Then select 'Add to ignore list'.

I also had this detected today when doing a full scan, after doing an update.

I run AVAST Quick Scan daily, except for Fridays when I do a Full Scan. On Fridays after I do the Full Scan, I update and run MBAM and then update and run SAS. AVAST hasn't found anything for a week. MBAM and SAS didn't find anything last Friday.

I quarantined the two files. When it comes to registry values, I don't know anything. Since nothing was found for a week, how could it be a malware file? I'm just trying to understand it.
