Windows 10: Trojan.PRForm.A Solved

  1.    04 Jan 2018 #1


    Hi. Is there any way of finding out where I'm getting this virus from? The alert in the attached pic pops up many times a day on my PC. I read that CCleaner might have been the original source but I've uninstalled it and the alerts keep coming. Thank you.

    I have read that most "On-Line" scanners will find and clean out this Trojan.......

    You might want to do an online scan with F-Secure......hopefully that will solve your problem...

    Hi Dortmunder,

    That does appear to be the CCleaner installer that was compromised, V533.6162
    Check your version

    Use the newer versions of it V 5.34 or higher, and also according to news reports, an automated update to the CCleaner Cloud version has addressed the issue for that version.
