I've received several mails from Avast in the last week or 2 trying to sell me stuff. I've unsubscribed yet keep receiving mails.
When I go to the bottom of the mail and click 'manage email preferences' I either get a redirect error, or when it works I find that all the unchecked boxes are again checked! Which I certainly haven't done!
Ignoring and reverting preferences is unacceptable, as frankly is having to opt out of mailings in the first place.
So, Avast; STOP SPAMMING ME!!!!
