As advised I am starting a new thread. My computer was recently infected with the "spylocked 4.0" Trojan. I have McAfee, Spybot S&D, Windows Defender, and Ad-Aware all installed on my computer. Ad-Aware was the only one that found and removed the the problem. However, if I go to the control panel to remove programs, the is a program listed called "Windows Safety Alert" which claims to use approximately 5 gig of space on my hard drive. If I click on the change/remove button the program installs "spylocked 4.0". I can find no other reference to the safety alert program on my hard drive. If I examine the properties of the hard drive there is a 5 gig discrepancy between the drive and all of the folders on the drive. Any comments on the situation would be greatly appreciated.
