XoftSpy 4.21 unchecking items?

XoftSpy 4.21 appears to be unchecking ISTBar & Mirar in SpywareBlaster. Could these just be false positives?
I've added the items to the ignore list in XoftSpy & scanned again, the items now remain checked in SWB.
Have I done the right thing?
I don't usually have problems with XoftSpy 4.21 finding FPs.
Thanks in antis,

Should have also said: The items mentioned above were not found by Ad-AwareSE, SpyBotS&D, ZoneAlarm Pro, MS AntiSpyware.

 

Yes they are False Positives with a XoftSpy database dated prior to March 15th. If you update to the latest March 15th XoftSpy database(DB-162).... these are no longer Falsely flagged by XoftSpy. In fact they cleaned up a couple of other FP entries that I purposely keep in place just for this purpose of checking programs accuracies.

This is also similar to the AOL Spyware Remover FP problem you had a few months back in regards to the registry entry that program was flagging....which happens to be once again the location SpywareBlaster places it's Restricted Sites entries.

HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains

 

Thanks very much for the comprehensive answer Bubba. Your reference to the earlier, similar problem gave added context. I now feel much more confident when dealing with FPs,

I've updated to DB 162, removed the two items from the ignore list, scanned again, checked SWB & all is well, bravo!!

 

I was hoping that would be the case
