Whenever i disable the ekrn service I cannot open files in office 2007. I continue to get a "file * is not available" until I start the ekrn service. I am using nod32 v4 and Windows 7 x64. Is there anyway to open files in office without turning on the ekrn service, I am a fairly safe user and don't require the constant use of an av program. Edit 8/06/2009 I tried disabling the document protection but as stated by Rmuffler it just comes back on. I don't think its something built into office 2007 because when i used nod32 v3 and disabled the service i did not have this issue.
