3 licences, 1 wrong machine

Hi!

I have a 3 pc-Pro-Antivirus licence.

After installation program automaticly found:

  1. the pc I installed Pro-version, good
  2. my android-device, good
  3. my friends pc, not good

Reason for the last wrong pc is, that I installed that friends pc:s Free Avast, a couple of years ago, and gave my email-address to its licensation…

Q: Is it ok, I go to my Avast Pro’s “My Devices” / {the wrong pc} / Settings - and press “delete from account”?
(My friend does not loose his Avast-free-protection. + I can add another third machine instead…)

tnx, Luti
