NIS Won't Open - Error message

Norton Internet Security won't open on my computer. When I try to run a LiveUpdate or Quick Scan, I get the following message:

 

c:\ProgramFiles(x86)/NortonInternetSecurity/Engine/18.7.0.12/uistub.exe

 

Unspecified Error

 

Any suggestions?

Actually, I never got to even attempt this.Turned out my computer was infected with a nasty virus (ironic, huh?) So ended up having to do a full system restore. Thanks for the help, though.
