If you do not register the Home or buy the Professional, after the trial period, you won't be able to update the program or the virus database.
Thanks, Tech. I do have a free license that is still within the year period. However, it is no trouble to get another if necessary.
I may trial another AV just for fun, but if not I find Avast my fall back AV. It always runs without conflicts. I do think it profits from the addition of something like AVG AS.
It is interesting that on the last AV Comparatives test AVG Anti-Malware, which has the AVG AS as part of the application shows up much better than in the past, and I believe that Avast would also have a detection rate several percentage points better than now, which isn't bad anyway.
Best,
