Your Computer Appears To Be Correctly Configured...
I recently upgraded to Windows 10 and did the uninstall/install routine for Bitdefender, per your web instructions. Although things were fine for a few days, all of a sudden, I started having DNS problems.
Upon identifying that my issue was a DNS problem, I spent time attempting many different solutions, i.e. flushing cache, attempting to renew DNS. One was to restore a prev version of the system (Windows Repair). After two attempts, I discovered I was not given permissions to certain files/directories. I then spent time trying to figure this out, which included turning off all BD services...that didn't work.
My only solution was to completely uninstall BD from my system. I'm now back up and running, though w/o BD services.
Has this issue been addressed, or have there been any quick fixes to BD causing the DNS problem?
