Holystic, also called TROJ_DYFICA.AW and TROJ_HOLISTYC.A, is a ActiveX dialer.

The following is some of information found inside preload.ocx: "MFC42.DLL http://www.holistyc.com/error?dll-not-found http://www.holistyc.com/error?holistyc-belongs http://www.holistyc.com/error?Dowload-failed http://www.holistyc.com/good?CreateProcess-ok http://soma/ http://www.holistyc.com/ netpond.com deltino.com gbtelecom.com .mtree .climaxbucks.com .cocktailcash.com .avenuemedia.com .sextracker.com .btinternetpayments.com http://www.holistyc.com/error?Internet-open-failed http://www.holistyc.com/error?Internet-open-url-failed http://www.holistyc.com/error?failed-to-create-file Sorry there was an internet problem please try again!

The following is description of preload.ocx, provided by a company representative: "It is a dialler ActiveX control. We used to use this for our premium rate dialler which we no longer operate. The idea was that if you wanted to re-run the dialler you would not be prompted for to agree a digital certificate second time around. We no longer run premium diallers as although ours was completely legitimate most of the competitive products were not and the market got a pretty bad name. You are quite safe just to delete it."
