Yesterday (21 Sep) when I turned on my HP Compaq CQ58 running Win 8.1 my free Zone Alarm antivirus/firewall detected malware in CCleaner. Before I could disinfect it my PC froze and I eventually had to restore it to an earlier setting to get it back. I discovered that I had CCleaner version 5.33 which had been hacked and contained a virus. I uninstalled CCleaner (won't be installing latest version) and did a full PC scan using Zone Alarm-nothing found. However I now have the problem that when I logged on to the PC it said it was unable to log me on to my Microsoft account and logged me on with a local account. When I go to user account settings using the charm 'change PC settings' I ask to log on to my MS account and get the following error message: "Sorry, we can't connect to MS services at the moment. If this problem persists search for 'network problems' on the start screen". I get the same message if I try to create a new account user. I have checked that the Microsoft account sign in service was running and set to manual. Changed it to auto and rebooted, same problem. A google search reveals a great many people have had the same problem for many years up to present time with no solution. I tried the MS account troubleshooter which doesn't recognise I have an account. Anyone got any ideas please?
