browsers not working well??

Since a few days my browsers dont work 100%. For a page I manage I cant edit fields. For another nothing happens when I click on buttons.

Tested on ie 10 and chrome - similar problems

I made a fulls can yesterday but Avast hang at 99%

I have checked for unusual tools in browsers

Version 2014.9.0.2011 (paid version) On Vista

Having problems with websites for awhile here also. Using updated Internet Explorer 11, & Avast Free version 2014.9.0.2011, some websites not working correctly, for example I am unable to successfully login to my ISP’s website among others. Tried logging in on another computer without Avast using IE11 and was successful. Tried disabling Avast Web Shield but was unsuccessful & then re-enabled Shield. Tried disabling the Avast IE Browser Addons & then was also successful. I hope this problem is corrected soon.

This is a known issue and should be fixed in the next release.
It seems to be fixed in the new beta (v2014.9.0.2012 beta) http://forum.avast.com/index.php?topic=144768.msg1049924#msg1049924

If you don’t want to use the beta just disable the “avast online security” plug-in for now.

edit: There are still issues when using IE in “enhanced mode”.

I had to disable webshield completely in order to be able to do my work online. As a result I did not feel adequately protected so uninstalled Avast for another AV. I will come back to Avast when they sort out all their recent quality issues.
