For over a month now, ClamWin has been finding a False Positive in Marvel Heroes:

The following files are Digitally Signed by Microsoft Corporation and may have been incorrectly detected as viruses:
Steam\steamapps\common\Marvel Heroes\InstallDependencies\MSVCRT13\vcredist_x64.exe: [Win.Trojan.Agent-1426210] FALSE POSITIVE FOUND

I don't recall what all the messages said or if it's the same virus being falsely identified, but it happens a lot.

Did you check the name of this/these forums? It is the ClamWin for Windows forum. Sorry--we can't help with any version of Clam AV.

Regards,

Sorry about the confusion, that's the name of my Mac program and I mixed them up.

But yes, I am in the right place.
I know this for a fact because when I went into the help menu in the program and asked for the weblink to report, it sent me directly to these forums.

To clarify, this is the Windows version of the program and it is a Windows 8.1 system that I am using the program on.

You can check files with the Virus Total online scanner at https://www.virustotal.com/ on the web. I like to see at least 2 of these AVs detect something before I believe it is infected: Avira, Bitdefender, Nod32, Kaspersky, or Sophos. You can report ClamWin false positive detections to the Clam AV project (ClamWin uses its own Windows port of the Clam AV Linux program) at https://www.clamav.net/contact on the web. Be sure to select the correct link---report a virus, report a false positive detection, etc.
