I just noticed a strange behavior. If I start the PC and leave it without any interaction for more than cca 10 - 15 minutes (I mean I just push the power button and then don’t touch it at all) and after that I initiate some input (click on anything with mouse or press a shortcut on keyboard) the PC completely freezes. It is possible to open CIS GUI, but it immediately freezes too. The mouse pointer is still active (can be moved) but there is no interaction with GUI.
This doesn’t happen if I initiate any input within the first cca 12 minutes (just once is enough), after that I can leave it without any other interaction for how long I want and it won’t freeze anymore.
This also doesn’t happen if I permanently disable Defense+ (just selecting Disabled level is not enough).
The system freezes only upon user initiated input, any automatically launched programs and scheduled jobs continue working even after the first 12 minutes.
Can anyone try to reproduce?
XP SP3 (Czech)
CIS 3.8.477 without AV (happens with all 3.8 versions)
