I have had norton system works on my machine since 2001. upgrading every year, am now running 2004. Or rather, WAS running 2004. I downloaded spybot s&d and found some spyware/adware in my system which spybot removed. While downloading and installing spybot, I turned off my Norton virus protection and guess I forgot to turn it back on. After about a week, I ran a scan with Norton systems and it turned up that my auto protection was not on. I tried to turn it back on to no avail, would not respond to anything that I did. I ran a spybot scan again, system comes up clean. I finally out of frustration, uninstalled Norton and all of its components. When I tried to reload.....I get an error message "Error 1311. Cannot find file E:\NSW\NSW1.cab. Verify that you can access file and try again" I can access this file on the norton cdrom. I cannot make the system recognize it. I have been up on the Symantec net, tried all of their fixes to no avail. I finally tried to reload Norton System works 2003. Now this program had been previously installed also and worked fine. Now when I try to install it, I get the 1311 Error message, also saying cannot access NSW\NSW1.cab.....whats going on here..... Have I picked up a virus or spyware/malware that is screwing with this machine.....I have been at this now for about 8 hours.... pulling my hair out. Help if you can please. I have also loaded all the files from the cd to my hard drive into a temp folder and have tried to load the program from there....I do not get the 1311 error by doing this....and the program seems to load ok....but when I get my updates from symantec.....I get errors on my anti virus which says that I have to uninstall and re-install the program.
