updated to 11.1.2241 from 10.4.2233 and I think there might be a bug? when I try to email a link using windows live mail from firefox browser I get an error that file WLDCORE.DLL could not be found or shared? went back to avast version 10.4.2233 and everything works fine, tried disabling shields and error still occurs, this is happening on machines with Windows 7 Professional 64b and Windows 7 Ultimate 64b, my Windows 7 Home work ok as well as xp. Wonder if anyone else is experiencing this?
