AhResStd.dll

Hello
This is my first post and I have one question
I using Windows Vista 64
When I go to Windows Seciurity Center and I try Turn on avast 4.7 Home but this action is impossible because maybe I need AhResStd.dll you know content of the mistake is “Standard Shield Provider Not found”

please help me

Sorry for my english :))

Try a repair of avast. Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow.

If that doesn’t work try, uninstall, reboot, install, reboot.

Ok it working I did not have marked the resident protection
Sorry for problem
