I installed avast on my 2nd pc tonight and in my profile it shows the pc but when i hit the avast button on my taskbar it shows only and time trial version. I paid for the 3 pc deal when I got avast last month. Whats the problem.
You didn’t mention which version of avast. So I’m going at this a little blind.
Move/transfer the license from computer no. 1 to no.2. Then insert license into the proper place. 
You stated that you purchased a three computer package.
That’s a clue you “can” transfer the license from one machine to another
up to three computers. Dig out your trusty USB stick. 8)
