Hi there,
Congrats on the final version of Avast 5.1. Sadly, the web shield bug it is still present. I am using Firefox 4 beta 8 and when the web shield is activated there is very noticeable slow down in web browsing. All settings are default and this is a new clean install, no upgrade. Previous AV was MSE 2 final, which unfortunately it is performing good but VERY CPU intensive and still has the bugs from the beta version. So, I moved away from it to Avast. I would appreciate if you can help me with my issues. Thanks in advance, Ivan K.
