I purchased a new key for two years Avast Pro and my brother has avast pro also.
his key ran out, and all of a sudden he said his was working again.
his key ran out and he was here the other day and was on my computer.
i sneaked a peek at his computer and my key is in his machine too.
i asked him to remove it and he won’t. Said they won’t care or know.
I paid for this and don’t want any trouble from this.
is there any way to de-activate my key and send me a new one?
???
Almost sure they will but can you send emails to support (at) avast.com and vlk (at) avast.com (where (at) is @).
Ok can do
Looks like you need to password protect access to your computer.
honesty.
what a refreshing concept
Strange thing about this story is that Avast doesn’t show the entire key anywhere. (at least I couldn’t find it ???) So it is not likely that his brother took it from his system. And using the partial part of the key which can be seen in the “about” doesn’t work.
Ahhh but there are ways to find keys 
For example there is a little program called keyfinder that will tell you the reg key for ANY Microsoft Windows product on ANY machine
humm… sounds like his brother knows his way around/inside a computer…
possible it shows up in registry someplace?
For security reasons…
Connie, that won’t work here with avast…
cool… as it shouldnt

If he purchased it online alwil would of emailed it to him, his brother could simply of read his email, or if he got the retail version from the shop, it would be on the box. (i think)

Ok got my new key from awil.
thanks guys
my old key will be invalid then?
you guys make great software, and my brother should pay for his.
keeps you guys in business.
Good to hear, just an idea but mabey you should password your user account on your pc so your brother can’t steal it again.

Idid purchase it online thru shareit.
did password it now.
and he is not allowed up here anymore.
I hate thieves.
makes the rest of us look bad.
Most probably will be sent to the ‘black’ list
