Not sure, but I recommend something other than those 2. Both are.. sketchy(norton has more false positives and is the biggest bloatware I have seen in antiviruses).
Avast, Avira, AVG, Norton/Symantec, and mcaffee have quite a large amount false positives. AVG and Avira used to be great but are slowly going to the dark side.
I recommend for antispyware getting Malwarebytes Anti-malware, Spybot S&D, and running a scan with HijackThis!. Post the HijackThis! log as a .txt attachment here if you can and ill see what I find.
Another place I recommend going is
http://www.bleepingcomputer.com/ for assistance, they will have you get HijackThis as well, so best to get it now.
What you are getting are most likely false positives. Heuristics will check for programs/files with certain behaviors. If they match they may be flagged as a malware of a certain class that corresponds with the behavior.
