Norton keeps logging files with every IPS update

Every time I get an IPS update, I see several entries in Norton Community Watch with the Flags 0x00000001.  It keeps reporting C:\windows\syswow64\jscript.dll, c:\windows\system32\mshtml.dll, and c:\windows\syswow64\jscript9.dll.  Are these files dirty?  Full scan keeps coming up clean.  Also, I sent those files to Virus total, which says it is clean.
