It says: Dear user, your avast! antivirus will expire soon. Avast! antivirus has been protecting your PC and data for nearly a year totally free. Your copy will expire in 30 days.
However, my (free) Avast! expiration date is 27/03/2013 @3:24:12 pm.
What gives?
PS: I did have free Avast! previously.
Check your my avast account https://my.avast.com and see what is listed there on the Devices as that is where the information is retained that triggers the reminder email.
Thanks DavidR. As far as I remember I never signed up for a my avast account. So I tried to register now several times but there is a server error every time. Will try again, see what happens and if successful will post.
If you didn’t sign up to the avast account, then it couldn’t have come from that information.
Have you tried in the past to manually register avast on the avast web site http://www.avast.com/registration-free-antivirus.php, if so then that is a possibility.
I just succeeded in registering on my avast to get an account. There it says that the expiration date is Mar 27, 2013 so that’s the correct date.
I really don’t remember if I ever registered avast on the avast web site since my memory doesn’t serve me very well anymore. 
Must guess that I did because otherwise how would avast have sent me a wrong expiration date? Strange thing is that I purchased a new PC (Win 7) last December and an IT tech transferred info etc. from XP to Win 7 but he installed Avast fresh on Win 7 at that time. Had to uninstall and reinstall Avast last March 27, 2012. Now not sure if some Avast info from XP got transferred or if Avast just picked a random date of expiration due to non-registration. Who knows what exactly happened.
Hopefully with registering tonite the free Avast on my avast, all will be solved. I will have to keep a close eye on it for the next month or seeing if I will get any more emails from Avast?
Thank you so very much DavidR!!
PS: In the Devices there is only 1 expiration date shown and it is the correct date.
You’re welcome.
Hopefully you shouldn’t get any further reminders now your avast account is up and correct.
DavidR, hopefully I won’t get any email reminders anymore. If so I’ll be back. ;D Thanks.
No problem, glad I could help.
