Can't disable auto-protect: "pending remediation action"

Hello,

I have just installed NIS (22.5.0.124) onto a new laptop (Windows 7 x64) and all seemed to go smoothly. It did an initial scan and found a threat in a pre-installed copy of PowerDVD. I let it fix it and paid no more concern.

Now I need to disable auto-protect (to install some ancient CAD software) and "Disable Auto-Protect" is greyed out. If I go to Settings->Antivirus the options to disable Boot Time Protection (I set it to aggressive after install), Auto-Protect and Removable Media Scan are all greyed out with the explanation "These settings cannot be changed due to a pending remediation action. Restart your computer to resolve this issue". Several restarts have not resolved the issue.

I have NIS installed on numerous other Win7 machines (earlier versions of NIS) and haven't seen this before.

Does anyone have any suggestions ?

Thanks

Gary
