I have been dealing with some malware for about the past 9 months, and have tried many things but they have not seemed to work. This started after I was out for a week and allowed an 8-year-old girl free reign over the computer. For about a month, things were going fine. Then I started receiving a bunch of ads on my web browser and my desktop. After 3 months of that, it got more serious. Some odd programs that were not downloaded by me started showing up on my computer so I downloaded Malwarebytes and and scanned it. I took out 30 some programs and I thought I was clean, but random programs kept randomly downloading on my computer every once in a while (which Malwarebytes picked up) and would not stop. Then today I came home after a week of not using my computer (Which only I could use after the incident started) to find my anti-virus shutdown and am unable to find any way to re-enable it, and I found a minecraft mod pack file thing filled with microphone records from my recording software and other odd things and deleted it and deleted it from the recycle bin, then I found there to be a dozen or so WAV sound files in my recycling bin that I did not delete or download and found them to be deleted just recently. What should I do? I have made a Malwarebytes scan everyday I was on my computer, and the records were pretty clear for the past few days.
