I deleted some Chrome extension and it worked. I don't have the pop up anymore. Thank you for your help 
Hello Hind.
We'd be glad to help.
Could you click 'See details', on the threat detection pop up and share a screenshot (https://bit.ly/3bfwDpw) of it?
Which web browser are you using? Could you use a different web browser and check if you see the same pop up?
Hello I keep getting this popup wherever I surf on the web.
What can I do for it to stop?
I have been having the same issue and found no obvious answer via these pages. Did a search for the phrase servscrpt.de and came up with a Reddit thread on the subject. Whilst some cited extreme responses such as deleting AVG and move to a new provider and updating everything one thread came up with a response that seems to have worked for me but only did it 20 mins ago so I am waiting out for my next reboot in case it returns! The suggestion above says remove any unwanted Chrome extensions but alot of people won't necessarily know what extension they may have or what they are for. The Reddit thread suggested removing Crosspilot well I disabled mine and hey presto no AVG pop up so it definitely seems to be a Chrome extension issue. Try that and see if it works for you.
