Good evening.

Since two days now, IE, Firefox or Opera won't start by double clicking respective icon. Nothing happens.
Installed antivirus:Avast.
I run a full system scan. Result:nothing found.
Also, tried uninstall & reinstall Firefox:no luck.

Would you have something else to suggest to help me?

Thank you for your time!
