Make sure y'all somewhat, know the difference between cookies, Possibly Unwanted Programs and actual viruses.
Been trying the different AV's down the years - in on the very first iteration of Norton (Utilities) then several others down the last 27 yrs.
Been using the MS Win Defender some years now, cannot comment on it because it hasn't found anything !
Tend to run in Sandboxie maybe within a Virtual Mc (Win7 Ultimate) if playing with media stuff - Never had a real Virus - Yet !
I always use freeby CCleaner prior to shutdown, not saying it is the best - But sure it isn't so bad, removes the garbage which could be flagged up by Superantispyware or Malwarebytes.
