I've been googling about my problems and this site seems to be the place to go when you suspect malware is in your system. My problems have been persistent for a couple months already.
The two things I could pinpoint so far:
- First, google search is asking me most of the times to complete a captcha to proceed with my search with a message saying there have been too many requests from my IP. Sometimes I have also been redirected to www.searchinquire.com when searching from the address bar. There's also some redirecting and popping windows every now and then in specific sites that could be related to the problem.
- Second. Every now and then I see my Chromes CPU usage in the Task manager reach as high as 70% (in a Phenom 1100T - 6 cores 3.3GHz) when it's pretty much idle, with 1 or two tabs opened to Google home. When expanding the Chrome task I see there's one in specific taking 69%, while all other chrome related tasks keep idle. It's as there was a coin miner running from Chrome or something.
My chrome's only extension is uBlock origin, with no Themes or anything added to the vanilla installation.
So far I've tried de-syncing my Google account to chrome, deleting all synced data in google servers, deleting cache and all browsing info in chrome, resetting settings, deleted Chrome and any Chrome related folder I could find in programs, appdata, etc.
I've also had Malwarebytes, ADWCleaner and Defender running periodically and finding nothing. First time I ran Malwarebytes/ADWCleaner a month or so back it could find some PUP infected files in my Chrome appdata folder. Since then I've removed it, reset Sync, reinstalled Chrome and scans don't show any infections.
Any suggestions on how to proceed?
Help and advice are appreciated!
