Hi Blade81
My apologies for the delay in replying to your last post. More hail, strong winds etc kept me offline. We're having a lousy winter!
Thank you so much for all your help.
I feel awful for not being able to say this sooner and hope you didn't get the impression I wasn't extremely grateful.
I followed your guide for securing the system and preventing any further problems. I've set up schedules for anything that doesn't do updates automatically. Microsoft update is set for Auto. Windows firewall is enabled, and the router is password secured.
I made the recommended changes to Internet Explorer [the only time I use it is for Microsoft sites].
The computer is still showing clean scans, no signs of nasties anywhere.
Once again, Thank you so much
Regards
LG
