I keep receiving a pop up telling me that my free avast is expiring and that in need to install the update. When I try to install the update it says I have the most updated file, but the pop up keeps coming back and I can’t get rid of it. can anyone help?
Hi Sooner, welcome to the forum 
Can you give us a screenshot of this popup, so we can see exactly what you mean and then someone can provide appropiate help?
Scott
do you using avast 4.8 or 5?
register your avast again…i think your registration will expire soon
I guess he/she is still using the old 4.8 version…
if you are using avast 4.8, upgrade 5.0 as soon as possible
if you already using avast 5…register avast 5 again…your free license maybe expire soon…free registration are here
That’s not possible, as avast 5 isn’t out for a year yet… 
oh i forget it 
It is possible, if avast! 5 was updated over avast! 4, the registration is carried over…
Regardless, we need to wait for the OP to reply.

Good point, Scott…
Still I think from the way the question was asked, it’s a 4.x installation trying to update to 5.x, but sure, let’s wait for the answer of the OP.
