Spybot 1.6 works better than 1.5.2 (ouch, it crashed the graphics card.). But I found that my system resources could not handle 1.6 either. I deleted 1.6 exe and overlayed 1.4.
1.4 Works fine except for one file: trojans.sbi 10/15/08 1.39PM has a problem. Scan hangs until I click OK regarding it. As did the privious file.
My system has a 900Mhz Celeron III, 256 Mb RAM.
