With the newest version of avast I went through a lot of problems. Installed on a clean Windows 7 machine and that is where the problem started. First I was not sure if the issue was avast, the website or the IE. I thought IE because Chrome did not have same issues. All HTTPs sites were rendered broken and I worked for a long time working this out as I did not try any of them before installing avast. Tried turning off the shields but that did not help. Finally I figured out that if you turn off the avast browser add-on's it fixes everything. This only effected IE not Chrome (which I hate). Of course I know how to deal with this now but for the general non techie how would they ever figure it out.The webpages all had different issues. Some logged you out, some would not display certain things and others just would not work at all.To stop this from happening to anyone else I would highly suggest when installing this version of avast to make sure to do a custom install not the standard install. When you get to the screen that shows the items to be installed uncheck the option to install 'Browser Protection'. avast will now be installed without the browser add-ons and you will not encounter this issue. You will also not accidentally turn the option on again if you turn it off.avast should warn about this issue during install but they do not. Lots of time wasted but if this helps someone else great.I almost walked away from avast over this. Faster browser now also. Review details
