I stupidly switched windows defender real time protection off, and browsed the web for full two hours before realizing it. The damage was already done at that point.
Google Chrome is the only thing that is affected - I was getting pop ups on my desktop with advertisements but I installed Avast Internet Security (because I was locked out of accessing windows defender, something to do with groups that I later resolved) and that took care of the pop ups.
I paid for the avast internet security package for one year and ran several types of scans after that to remove all types of malware. I ran a boot time scan, a full pc scan and some quick scans. All of them revealed virus/malware that I removed.
However, now when the scan says nothing found, the malware still persists. Namely, if I didn't have avast extensions in chrome, I would still be getting redirected to different webpages, and the top 3 searches in any google search are still paid advertisements from the malware.
After every couple of minutes, I get a notification from avast that something called Pchunter64al.sys is being blocked. However, on system scans, nothing shows up.
I ran a tool called Spymaster and that revealed like 5400 infected files, but the removal feature of it was also a paid feature. I found the tool after I googled "remove redirect to watermelonshake.com"
Malwarebytes also revealed a clean system.
What do I do now?
