Persistant funlove virus wont go away

Hello,
I have a problem with one of our servers which our net shild 4.5 virus software reports that the funlove virus has infected 7 files. Although the virus program cleans these files when found they appear every single day. I am running the latest dat files in Net Shield and have downloaded a fix from nai.com to try and sort it but to no avail. There is present in the system32 folder a folder called flcss.exe and there is no file anywhere on the server called flcss.exe or a process either which should mean that it is not possible to be infected with this virus.But it is still been found by net shield every single day. Is there any other way that we can finally see the back of this virus once and for all. Thanks in advance.
