Hi, I have a problem. I bought a license for the PC version of avast! IS on the 20th of April. Just recently I sold my PC and bought a Mac, so my question is if it is possible to change license of avast! IS for a Mac? I appreciate your help. Thank you.
Best regards,
Adrian
Hi…
I’m not sure about that. You would need to contact avast (Alwil) to see if that’s possible. Go here and click on “Show e-mail address” under “Sales inquiries.” This will give you the address to write to. 
Or, if you don’t have a POP3 client, you can click on the “Submit an inquiry online” option instead.
Hope this helps…
Regards…
