If they fail then try homeopathy , they share they same degree of efficacy
OP
Have you tried a good malware remover , eg Malwarebytes ?
You shroud be able to do a OS reset from within Windows or better with a recovery disk

Or best of all , if you have the confidence, then a completely clean install on a formatted drive
Seems unnecessarily snotty to me...I was only trying to help.
You may be right. But this morning's scan has, eg, reported:
Doesn't strike me as particularly 'homeopathic'. Unless it's BS, which I don't believe it is, it's just about to, among other things, free up almost a Gb of space on my HD. Other things being equal, seems to me that's worthwhile. And this is in the fortnight or so since I last ran it. How about if nothing comparable had been done for, say, three years? I've nothing against Malwarebytes - I use it myself every now & again. But this is the one I've been using on my family's computers for five years now, and they all run nice & smooth, with no problems like those reported in the OP. Given that it's free, and there's no downside, and it's a bloody sight easier and quicker than 'doing a OS reset from within Windows or better with a recovery disk', then I would've said it was worth a try. If the OP doesn't want to, fine.
