I ran a full scan today, and MWB reported 418 infections. They all relate to a program I believe to be genuine (it was downloaded from MajorGeeks, it is available from Softonic also, & I think it is on FileHippo as well). It is called PCWInBoosterFree, by Sorentio Systems (10.1.9.241). As you've probably guessed, it is one of those system cleaners.
MWB reports it as Rogue.PCWinBooster, and the reported infections are Registry Keys mostly. There were no other infections reported. It was quarantined and re-booted.
VirusTotal reports the file as clean.
This system is W10 Home (1803), 64-bit.
Can someone look into this please?
