I have purchased a replacement desktop scanner (Fujitsu iX-1600} to replace an old, similar scanner ( Scansnap S-1500 ).  

I had trouble installing it, until I closed Trend Micro (TM), now I can't scan without Trend Micr turned off.  The scanner service team advise me that this is a well known compatibility problem but had no advice on how to get round it.  I have added the scansnap functional folders to the exemption list on TM but the problem persists,  Is there a known fix?
