Every time Avast updates, either firefox or flashplayer (or both) freezes/becomes slow for a while. Everything returns to normal after the update message dissapears. Does Avast need lots of memory?
I don’t know but I find Chrome way faster than firefox.
Try looking in Task Manager to see how much memory Avast uses…
@ ITNoob65,
If you can’t answer the question, why are you commenting with totally unrelated information ???
This is probably because avast is downloading the update; if your internet bandwidth is nearly fully used by avast, other programs might slow down.
