PC/Laptop Security

We’ve got a PC and Laptop-which hasn’t been used for sometime. The PC has got Avast security software on it - up to date - but the laptop keeps saying to renew the subscription. I’m sure when I bought the laptop some years ago I “synchronised” the security programs with those on the pc. Can anyone tell me how to do it please?

Is this the free version or paid ? free version can be re-registered via the UI and going to maintenance/registration.

It’s the paid version

  1. Update to latest paid version and make a new purchase http://forum.avast.com/index.php?topic=108170.msg856869#msg856869
  2. Or install the latest free version (same link)

Either way download the desired version before uninstalling.
You may need to do clean installs either way follow the instructions http://www.avast.com/uninstall-utility
Use the utility for each and every version of avast.
