Local scan wont complete

Sme here - it scanned for 2 days.  Although it was supposed to be a local scan - the threats were some deleted files which were stored on my Time Machine hard drive.  Quarantine Manager said it would remove them but then said I had to do it manually.. When I tried to remove them from the Time Machine - it said I couldn't interfere with BackUps.  So then I told it to ignore the LaCie Hard Disk.. Started up again on the scan - long scan.. 2 days.. Would you believe it scanned the LaCie again!! .  So I tried specific custom scans - My home Folder 4 hours later it is still counting items - which seems strange cos the total scan counted items in about 20 minutes..  

I really suspect that this is not working and I guess we just have to thankfully accept that there are no real problems on mac.  The two files found were .exe files which do not effect Macs.
