Rename icqsrp.exe to something like icqsrp.ex that way it can't start at all - I did it and ICQ still works fine. Then if you want you can also remove all the ad - banners etc. just do a search on google -- ICQ banners or removing ICQ banners / ads. I've done this and ICQ still works great, but is secure and banner free.
EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
