It would help if you could clarify whether you ran the PestPatrol BEFORE you removed LimeWire and re-installed it...
Were the 'dataminer' files there before you removed LimeWire and were they deleted from your system by PestPatrol?
Did the same number of dataminers attributable to LimeWire appear AFTER you did a 'fresh' install of LimeWire ?
And, did you remove ALL LimeWire folders and restore registry settings in the process of removing LimeWire ?
If what you are describing was a common occurence due to LimeWire than these forums would be awash with people screaming their heads off about it !!!
