Well, I just bought this new desktop literally a day ago..and I wasn't too high on having Norton A/V on it, so i proceeded to uninstall it and restarted my computer. When I restarted the computer, I got a popup claiming "windows explorer has stopped working" it also has alternatives on the bottom wheter to check online for a solution and restart the program, or just restart it. When I viewed the problem details, this is what comes up. Problem Event Name: APPCRASH Application Name: explorer.exe Application Version: 6.0.6000.16386 Application Timestamp: 4549b091 Fault Module Name: qzviz.dll_unloaded Fault Module Version: 0.0.0.0 Fault Module Timestamp: 46137c58 Exception Code: c0000005 Exception Offset: 100018d4 OS Version: 6.0.6000.2.0.0.768.2 Locale ID: 1033 Additional Information 1: 8d13 Additional Information 2: cdca9b1d21d12b77d84f02df48e34311 Additional Information 3: 8d13 Additional Information 4: cdca9b1d21d12b77d84f02df48e34311 I can access the internet and everything if i don't click on restart the program, but i can't get into any other programs, while it's still there. Any tips would be appreciated on how to fix this problem, oh and btw i'm running windows vista OS on this computer.
