Laptop behaving peculiarly

[tomt]

When I used Microsoft some years ago I actually had a virus that slowed down my system. I installed Malwarebytes and removed it. It worked for me, also my granddaughters laptop was running real slow and I advised her to download a free Malwarebytes and it showed she had over 400 viruses and trojans which she removed for free. Laptop ran like a brand new one after that. Not bad for free. Anyway, my two cents. What the heck it`s worth a try.
