Ever since the last Auto-Update of avast, IE6 quit working. Reinstall if IE6 will not correct the problem. Clicking the IE icon just give you the standard error and asks if you want to send a report to MS. The only way to get on the internet is to get into an explorer windo the typing a www address. Even this acts up and does not work properly. QuickBooks accounting also fails and says IE6 (required software) is not installed. This problem started immediatly following the Avast download.
