Crashed repeatedly on trying to run an upgrade from install package, upgrade via GUI not available/not working.
Clean uninstall, then fresh install of AIS with only antivirus and firewall. Yet again the sandbox was clearly seen installing and interferes with IE9 .
Despite being reported numerous times the same installer issue is present. Fesh install , go to Control Panel > All Programs > Avast > Change > add or remove any feature > restart and WebShield no longer functions , repair will not fix this so a re install is required .
Firewall fails to load/start on each restart. Have tried repair, run a new install and the issues remain so Avast is now permanently off my Win7 partition, just using avast4 on my Linux install which will be my primary desktop from, now on.
