2 days ago my internet on school worked fine. That evening i installed some editing plugin on google and it braught some annoying spams which i removed already now. But the next day my internet access on school was blocked because my pc might be attacked, it said to do a complete virus scan and that didnt solve it. an other option was reinstalling windows which i really dont want...
i dont have any problems so i dont get what is wrong but what i do get since yesterday is this random error popping up sometimes:

and somehow a few moments ago i couldnt connect to any wifi anymore cuz of a wifi driver problem but a reboot solved that.
Ive searched google but its all about another missing file i cant find this one. Can anyone maybe help me to solve the internet attack problem and the acces denied screenshot?
