How disinfect PC after reinstalling Windows, Bitdefender? virus symptoms still there..
Hi,
- Virus symptoms before re-install: lots of clicks on the screen, random drives to internet sites, clone wi-fi network and connect there automatically after restart, difficulties in pressing the shut-down button, etc
- Re-installed Win11 (2 times), installed Bitdefender
- After 2-3 days symptoms reappeared and the hassle reinstated on PC (symptoms per 1., above)
I am not a specialist have no clue of what's going on, hence could not get the hang of it; also, afraid that this would soon spread across on other computers in the local network.
Please help! Thanks

Had a conversation with the user via PM. Since being a novice, the user is unable to perform the requested steps provided by @Gjoksi and me. Hence, had to personally create a batch file for him which could perform all the functions like cleaning of temporary files, resetting network settings to default, resetting windows update to default and resetting web browser to default.
