Possible incorrect Detiection

This looks like an incorrect definition problem to me. I've also had this file flagged up as a trojan on two machines, one in system32 folder, and another in the softwaredistribution folder. It needs urgently correcting otherwise folk are going to quarantine a healthy file.

AVG has just reported c:\windows\system32\provtool.exe is infected with Trojan horse SGGeneric1.BVSM however the file doesn't appear to have changed since November 2016 and I've just run it past 60+ online virus scanners and they all report it clean.

Hello John,

Thank you for providing the screenshot.
This could be a false detection. In this case, I request you to repair AVG Internet Security program once as mentioned in this article: http://avgread.me/1BVxDSY and if the same threat appears, do let us know.

Hello Mike,

Yes, I certainly agree with you. This could you be a false detection and I suggest you to check if the AVG program installed in your computer are up to date. Please also run AVG repair, to make sure all the corrupted updates are removed and a fresh update of AVG is installed in your computer.
