Now I get a notice saying the pervious warning is a hoax so I include that comment as follows for you to evaluate.. I wouldn't delete this file. I checked this out at the following URL for hoaxes of all types, just on the possibility that someone out there with a warped, perverted sense of humor might be having fun watching others (all of us) mess up our hard drives by deleting otherwise valid, legitimate files. Definitely a hoax. Here is the address, check it out for yourselves. http://www.symantec.com/avcenter/venc/data/sulfnbk.exe.warning.html
