JSCoinminer Crippling my Computers
I'm getting alerts every few minutes such as: Norton blocked Web Attack: JSCoinminer Download 6 (or 8). About half the websites I try to visit are blocked (intrusion attempt by same.) Even norton and symantec websites are blocked for malicious attacks. Live update does not usually run (likely web access is blocked.) It just started one day on all four computers in the house. All run Windows 10 and Google Chrome. Same thing happens with MS Edge browser. Same thing happens using my phone as hotspot (i.e. different ISP, bypassing my router).
I ran a comlete Norton scan, Malware Bytes, HitmanPro, Emsisoft. All clean. I removed and reinstalled Norton Security. Same problems. I removed Chrome, thinking maybe an extension was causing problems--no luck.
I don't know what else to try other than to uninstall Norton Security. That solved the problem, but not really a solution. Interesting that even then HitmanPro (realtime monitoring) detected some hits from coinhive.com, but not nearly to the same degree.
I've read that cryptomining scripts can reside at websites, user computers, or intermediate routers. Not sure what is going on here. Any suggestions? I'm pretty much at wit's end.
