Hello I have looked around in here but I haven't found any results that are exactly like this. When I run the rootkit scan, I basically just get hundreds of entries like this:
Type: File
Object: dotNetFx40_Full_x86_x64.exe:$CmdTcID:$DATA
Location: Z:\cobian backup\windows reinstall backup\
Details: Unknown ADS

But I don't know what that means or if I should delete it. for some reason my system is running abominably slow but spybot, malwarebytes, and comodo do not show any detections :(
