To be more specified: Its' obviously because of an extra apostrophe ( ' ) after the word "malwarebytes" inside the SQL clause: INSERT INTO ActiveApps (Started, Exe, ProcID, Resumed) VALUES ('2009-08-20', '\device\harddiskvolume1\program files\malwarebytes[size=5][b]'[/b][/size] anti-malware\mbam.exe\', '2544', 0)
