I downloaded bitdefender upgrade to total security and next morning when i turned on pc i got this window stating i have google error line 0. I searched this and apparently i have a worm. I did a bit defender repair but this did not work. I use to have norton. their subscription allowed free removal. bitdefender wants 90 bucks i think? Is there anyone who can tell me how to get rid of this worm>? I did a utube search and other website but they were either lying about how to remove this worm or else they gave poor instructions. i almost crashed my pc bc of one of these instructions. i'm going back to norton when my sub is expired
