Down load
Microsoft Standalone System Sweeper on another machine.
Follow the instructions.
Run Malwarebytes. Let it update, if required. Run a full scan and remove any rubbish found.
If that doesn’t do it…
• Unplug the bad machine from the Internet.
• Start it and Log On.
• Log off.
• Log on and then immediately start pressing Ctrl/Alt/Del several times until you get to the System configuration box. (msconfig)
• Look for any unusual Startup items:
(random characters).exe
avsuite.exe
avsoft.exe, or something similar which may be connected to the message you are getting. Google for ident if not sure.
• Kill them! – oh, alright, untick the box in the Startup Item column. Apply.
• Run Malwarebytes. Let it update, if required. Run a full scan and remove any rubbish found.
• Install Microsoft Security Essentials. Scan.
• Stay away from web sites not on the ‘Main road’. Never click on links in emails. Use a Firewall.
