AVG Antivirus is throwing up a threat detection for CefSharp.BrowserSubprocess.exe

[rfgamaral]

User @faudau created this issue on my SlackUI repo (https://github.com/rfgamaral/SlackUI/issues/7).

I'm wondering if there's anything that CefSharp can do to avoid this issue or if the solution is to get AVG Antivirus software to know that this is a false positive and they should not trigger a threat for this file.

Not sure if you guys were aware of this already but I though you should know.

On what CefSharp version? x64 or x86? Is it still an issue if you upgrade to latest 39 version?

Upstream response to a similar issue with a CEF file (cef.pak) at http://www.magpcss.org/ceforum/viewtopic.php?f=6&t=12362&p=23616&hilit=antivirus#p23617. It has some generic advice on what to do ...

I can't really answer those questions cause I don't use an AV...

I uploaded my source-built versions of CefSharp.BrowserSubprocess.exe to virustotal.com (x64 results, x86 results). No detection by AVG.

My suspicion is this is not related to the binary contents of the file, but due to some heuristic based on the characteristics of the file, how it is installed, signed or unsigned, etc.

@rfgamaral I think next step is to ask your users that report this problem to drill into their AV software and get the exact reason for the file being detected.

@jankurianski Thanks for looking into this. For now only one user is reporting this issue and he never replied back. I'm closing this issue and leaving the one my repo opened for while. If he doesn't get back to us I'll close it too due to inactivity.

I'll leave a comment here if needed and if he indeed replies back.

@rfgamaral Hey - I am running into this issue as well. I am using Symantec Endpoint Protection. Any idea what I can do?

@rfgamaral Avast AV also detects it as a threat; infected with IDP.Generic
