My mozilla freezes for a short time, for a few seconds. Can it be because of all the data it have to load?
Are you sure you have enough RAM? if you use more RAM than you have this can happen
firefox is good
This is not the topic for that
BTW i want to tell that IE isnt that bad at all the new one is verry efficient, but you have Google Crome, safari and much other bowsers to, the bowser war is about to begin and im not kidding!
I found mozilla good, but its not good if you want to protect your personal files.
Also some tips for better security
Vista has a much better system than XP
There are several free good Anti virus systems and anti spyware systems for example AVG free and Search and Destroy
do you torrent and downlaod stuff much watch out for keygens mostly that installs malicious software, so scan your PC if you used one with both anti virus and anti spyware.
