Thanks jaishankar, i noticed your reply after doing my new update.
I'll try to do that, what you wrote, tomorrow (though i have had problems with safe mode before..). It's late now.

I did about:buster scan and now my computer runs faster and there's no pop ups anymore. Search Extender etc has been vanished.
Now i scanned all my drivers with BitDefender Online Scan, it found 38...

Hi

I did read some threads here in daniweb, but i decided to register and make an own thread.
I have weak english but i'll try..

i've had problems with slowness of my computer and pop-ups etc....
