I di do not need or want these completely useless and unnecessary 'idle time' scans two or more times per day. Every time it runs, the PC becomes completely unresponsive for other software to run and simply irritates the h**ll out of me. It is quite ridiculous.I have never had a malware or virus infection in the last two decades. I do not need to have that checkred out every few hours.
Unless somebody tells me how to stop this, or at least change the stupidly short maximum time from 30 minutes to something more reasonable ( like 24 hours), I'll have no option hbut to abandon NAV completely and permanently after more than ten years.
