I keep getting this error when I try to update my virus definitions LU 1875. I have 49 days left on my subscription.
I also get this message. LUCALLBACK PROXY.EXE BAD IMAGE

And this also. CLTLUCBK.DLL IS NOT A VALID WINDOWS IMAGE

Any ideas on what this is? I ran the norton autofix and that did not work.

Thank you
