I have got this problem at the past week: All of sudden my Firefox window freezes, I can see some website elements not loading (images etc), and then when I close Firefox (after minute of struggling), and try to start it again, it gives weird error messages like: "not enough resources" or "not valid Win32 program" or "application failed to initialize" or something. I can't launch any program after that, not even CTRL+ALT+DEL, but if I open the taskmanager beforehand, it stays open correctly, so it only fails to start new programs. I am pretty sure this is because of Avast! Also, my Windows windowses start to lose their icons and those error message pop-ups get really wide even though text isn't that wide, and the title isn't always visible, or the text.
Furthermore, I have noticed that every day (at past week) I start my computer, I get this Avast! window requiring me to finish the upgrade, I click OK every time but next day it comes back, even if I didnt upgrade anything. Maybe because I didn't click "install google chrome" ? Is that yet another dirty trick trying to force people to generate money for them?
Anyone had similar problems? I have latest Avast! currently (updated again today), and latest Firefox. I have got Windows XP SP3 (which does not have newest updates, around half a year old updates).
