How to respond to an unexpected log on request

What to do when a 'security message' asks you to log on

QUESTION For the past three days I've been getting a 'Windows Security' pop-up that says 'Logon to UKOnline.co.uk' (my ISP). It requests the username and password among other information, but nothing happens. George Malcolm

HELPROOM ANSWER I'd be very suspicious of any message that appears claiming to be 'Windows Security' when visiting a legitimate site such as UKOnline and asking for details. Run a full antivirus scan to check that malware hasn't already infected your PC. Next, use CCleaner to clean out your temporary system and internet files.

Finally, change your UKOnline password: it's possible that this login window is fake and has already passed your current details on to scammers and spammers. If you need help, contact the ISP via a web URL you know  - ukonline.net/contact - or a Google search - don't click the suspicious link.
