I have done the instruction above with no result alas.
I can also not find any trace of Ublocker anywhere. Consider this post is remade in a new threat I post a quick picture of the issue
This one will popup every 15min exactly.
Weird thing is that if I do a reboot of my system, its good and stays gone, but if I do a normal shutdown and startup of my system again, it's right back from the first start of Chrome and around every 15minutes, until I do a reboot again. (Im on Win10 if that helps)
Also in other posts I have read that this is suspected as a false positive? Is this the official case? If so can I then safety put this in an exclusion?
