Ccleaner Trojan Alert on Latest Version 5.36.6728-SOLVED
« on: November 03, 2017, 05:44:30 PM »
Hi All

Was doing clean install of Avast on Mom's PC, (The HP P6-2133W System) anyways after running the Avast removal tool in safe mode, rebooted to regular mode, and logged into Admin account, got alert ccleaner needed to update, so I was like ok i'll update it and clear Avast registry entires before I reinstall, anyways got alert for Trojan from that download, went into panic mode lol

Thinking maybe false positive from Defender, as shows up clean on every other system in the house,  in a moment gotta get Avast reinstalled on that system, don't really trust Defender lol


Possible False Positive, all other scans showing up clean

Virustotal results of ccleaner issue, looks definitely like false positive via Windows Defender before Avast reinstall yesterday on the HP system
