I scanned my computer using Outpost Spyware Scan and Found malicious system setting change in host file after quick scan. My Windows update from Windows website is working after removing Registry errors. I tried to cure this malicious system setting change with Outpost Spyware Scan but it failed.Also I am unable to Quarantine.
Malwarebytes Antimalware reported no malicious item.
When I updated my MVPS HOST file with new one, the same malicious settings detected again by Outpost Spyware Scan (Quick Scan) and it is cured this time.
I checked MVPS HOST file with Winpatrol it working.
