Hi, I have used combofix in the past with excellent results. This week I began to notice frequent browser (firefox 3.6.12) lockups, and slow page loads. I decided to run combofix. When I ran it, the first thing i noticed was that I got a strange popup asking me if I was attempting to use CFScript, and that it appeared to be "mispelt." Combofix never got beyond the "may easily double for badly infected machines" screen. The hard drive would spin for a few moments, < 1 min, and then nothing. After waiting 5-10 min and realizing nothing was happening, I would have to power cycle to reboot. I tried this several times hoping for a different response but of course didn't get one. I deleted the Qoobox folder and all references to Combofix, downloaded a new copy (from bleepingcomputer) and tried again with the same result. I have tried Malwarebytes and Spybot, both tell me my system is clean. My antivirus is Clamwin, and it is updated. Except for Combofix not being able to run, I don't really see any concrete evidence that anything is wrong with my system. I just "got a feeling" that it wasn't right because of the browser issues. But now I'm pretty sure it must be infected. Either that or I'm just not giving Combofix enough time. In the past I've never had to wait more than just a few moments for the scrolling numbers showing each Combofix section. But now they simply don't appear. The only log that is generated is catchme.log, and the only entry is the date. There were multiple combofix logs that I deleted, thinking that a fresh copy would generate and have more pertinent information. I would appreciate any help. Thank you very much.
