Chronic Hacking Victim Needs Help

[arizonensis]

As the title suggests, I'm no computer expert. I am, however, smart enough to figure out that my Internet communications have been compromised in a way that suggests I am the chronic victim of some kind of man-in-the-middle attack. In addition to scanning for problems that might be residing on my hard disk, I now surf exclusively with a VPN. Any help in resolving this matter would be greatly appreciated.

I recently ran a deep scan for rootkits and found the following in the registry keys:

Type: Key
Object: 8
Location: HKLM\SYSTEM\CurrentControlSet\Control\Nsi\{eb004a11-9b1a-11d4-9123-0050047759bc}\
Details: No admin in ACL

Type: Key
Object: 8
Location: HKLM\SYSTEM\ControlSet001\Control\Nsi\{eb004a11-9b1a-11d4-9123-0050047759bc}\
Details: No admin in ACL

Type: Key
Object: Svc
Location: HKLM\SOFTWARE\Wow6432Node\Microsoft\Security Center\
Details: No admin in ACL

I also found the following folders (yes, I know it's Norton, but has it been compromised?):

Type: Folder
Object: SrtETmp
Location: C:\Users\All Users\Norton\{0C55C096-0F1D-4F28-AAA2-85EF591126E7}\SRTSP\
Details: No admin in ACL

Type: Folder
Object: SrtETmp
Location: C:\ProgramData\Norton\{0C55C096-0F1D-4F28-AAA2-85EF591126E7}\SRTSP\
Details: No admin in ACL

My first question is whether anything above is a cause for concern. If so, my second question is how I go about remedying the problem or problems?

Thanks.
