On this computer I'm using WinXP Pro. Since updating to the new version of Avast 11.1.2253 I've experienced stuttering while watching videos and even typing through the browser. This doesn't effect me when I'm doing something outside of the browser, like watching a video etc.
I can only come to the conclusion that the problem is with the Web Shield. On the previous version I went to this page:
https://www.avast.com/en-gb/faq.php?article=AVKB203 and followed the instructions on improving performance by turning off some of the options. My browsing experience improved instantly.
I've done most of the suggested things on that page. But I've found that there no longer is the option to turn off Intelligent Stream scanning. So I've got the same issues back that I had a couple of Avast versions ago.
So I guess the question is, how do I turn off Intelligent Stream scanning in this version?
