Some computer questions

Again, everyone, thanks for all the info.  I do run Malwarebytes and have never found anything, but the fact is, the AMD PC is basically a photoshop PC and I don't do much on the internet with it with it either.  Not sure how Id pick something up.

Im guessing maybe there is something else going on if I shouldn't be seeing that much of a discrepancy.
