#Avast webshield slows browsing software
One thing that you might look at - the web shield is processing data in realtime, and there might be some clash or interaction if you have other software also providing real time protection.Enabling JavaScript and cookies in your web browser (I may be on the wrong track altogether but I wish I could see what is happening to packet retry level when the problem is present) In any event a reboot without changing the shields also seems to remove the problem.Īt this stage it appears that in my case turning off "use intelligent stream scanning" reduces the extent of the problem, however because the system can work for 95% of the time with no significant impact on performance, the problem is not going to be easy to find.

When this problem occurs turning off the Web shield completely does appear to overcome the problem, and turning it back on most often brings the problem back (although some times restarting the web shield cuts off access to the internet altogether and then requires a reboot). Restarting the browser doesn't seem to help. Access to the same site at the same time from another computer running Avast 4.8 via a common router is quite normal. If anything Firefox seems to be affected more than IE7. In fact there is almost no significant difference when the web shield is turned off and speed tests are carried out.įor the other 5% of the time, and at this stage virtually at random during normal browsing, internet speed with either IE7 or Firefox becomes really slow, and it doesn't seem to be on any particular site. I have uninstalled it on two of my PC's, and for about 95% of the time, my internet performance using either IE7 or Firefox and with the web shield on and using the default values is quite good. First, what shields do you have running - If you have the behavour shield running try (a) turning it Off and (b) uninstalling it.
