AVAST efficiency troubles due to former Norton antivir !

[DESTAR]

Hi

I have been using AVAST for more than 14 years , but the new PC that I have  inherited  was fitted before with Norton. I tried to uninstall NORTON, but I discovered  it was impossible to perform .
I asked to Norton, but the answer was very harsh and I replied with much anger . Symantec commercial policy is actually disgusting ! I am ready to do anything to revenge from this gang of mobsters!!
  I bought  AVAST anti-vir for this PC, then , the former Symantec Norton started taking the job by force, sending false virus alarm, and lots of unwanted actions, so that I can't trust my AVAST efficiency .
MY QUESTION :

HOW TO GET RID OF NORTON ONCE FOR ALL

Run there removal tool https://support.norton.com/sp/en/us/home/current/solutions/kb20080828154508EN_EndUserProfile_en_us;jsessionid=A1CA8D058C769E6CBA9651D0EFA2F163.4?entsrc=redirect_pubweb&product=home&pvid=f-home&version=1

Once removed you can run manual searches for "Norton and Symantec" to eliminate remnants

Thank for your quick reply . I downloaded the file, but The Norton pirate antivir is screaming to me " this file is full of virus " !! . Funny  walk .

Turn Norton off then try re-running the removal tool

No problems don't forget to finish up with a search for the Symantec and Norton leftovers, CCleaner will help remove bits as well and you could run the registry cleaning function it contains which will also find more junk.
