if not almost impossible. i get pages that just sit there and load downloads locking up and turning off eset is an instant fix. this just recently started within the last few days. at first i thought it was a firefox issue because it updated to ff 14 beta but as i said if i turn off eset it is a instant fix. also if i restart the system thing will be normal for a bit then as i browse the net it will start with just a few pages then eventually i can do anything. with the same result turning off eset fixes the issue. no issues with v5 in this regard at all.
