Hi, clever people! My P.C. is running Windows "Vista" 64-bit (Whatever that means; I'm an amateur at this game) I have had paid-for Avast P.C. Security for several months, and have been happy with it.
However, yesterday, when I switched "On", I got an on-screen message, in the side bar, saying that Avast is "Unsecured. Fix now". When I open the Security Centre I get the options to switch on Window's or Avast's firewall. When I try to set up the latter I get a message saying: "File System Shield provider not found". I haven't the slightest clue as to what that means! The only good news is that Window's own firewall was easily re-installed, so I think the P.C. is safe now, as far as that goes(
) Meanwhile, the "Unsecured. Fix now" panel in the side bar is still visible, and my Avast system seems to be inoperative.
Help and advice will be very gratefully received, thanks.
