The fssfltr_tdi.sys issue is caused by the Family Safety from Microsoft Security Essentials.
To solve this problem you need to uninstall Family Safety. If you can’t find it on “Add or remove programs” you need first to download and install from Microsoft. Then uninstall Family Safety
Probably you also need to remove avast! with avastclear tool and make a clean install.
