My Norton seems to be leaving behind this little thing called scanstub.exe, which I think is preventing further scans. What happens is: I open Norton, run the Updates. It downloads them without a hitch. Then I go to "Scans", and it comes up with the message: "A scan is already running. Please wait until it finishes and try again. In the Taskbar, Norton doesn't show up, but Scanstub.exe does, which seems to be associated with Norton. At present it's using 15,928 k of memory, and it will not allow me to end the process or process tree. It says "Operation could not be performed. Access denied". I'm the Administrator of this laptop. My system is Windows XP Home.
Also, all of a sudden there are a ton of svchost.exe process running, all of them taking up 2000 - 4000 k of memory. I can't figure out what they're doing either, but it has me wondering if this is actually some Malware thing that has gotton in my system disguised as a legitimate Norton file.
I recently downloaded Malwarebytes' Anti-Malware and it got rid of quite a few infections (I did both full and quick scans), but this scanstub.exe problem has persisted for a few weeks now. It only seems to cause this problem when I open Norton, get updates, and then try to scan. I believe I've scanned with Norton after this Scanstub problem had appeared once before, and it didn't find any viruses. In that case I had to restart my computer and then scan without running the updates.

It looks like you are using Norton 360, please confirm this and also let me know which version you currently have installed. You can check this by opening Norton 360, select the "Help & Support" link at the top of the window and then choose "About".
Scanstub.exe is the executable file that Norton 360 uses to perform a scan on your system and is not Malware. The symptoms you describe point to either a problem with the installation of Norton 360, a software conflict or a possible infection that may have compromised your system. Please make sure that you do not have any other third-party, real-time internet security products installed, as they can cause conflicts with Norton 360. Also, make sure that the Windows Firewall is disabled, as the Norton Firewall is handling this for you.
One of the advantages of having a subscription to a Norton product is that you are entitled to free product updates for the life of your subscription.
