I had just downloaded the tds-3 trial and on the first run it shutdown before I could even read what it was doing. This puzzled me so I ran it several more times with basically the same results but on a couple of occasions I saw 3 entries at the bottom in the ALARM area i made note of a file named 001.sys and a registery entry with a filename winupdate.exe. I did a search for the 001.sys file and was amazed at what it contained.. every keystroke I had made over the last 3 hours including 2 credit card purchases. I deleted the file. It came back. So then I searched Google.com for the 001.sys file and found out it was a file made by a backdoor trojan and found more info on deleting the entry in the registry and then deleting the keylog file. Thanks again for the wonderful product PC-Cillin 2004 didn't even make a sound. I had no idea I had any problems on my computer. Happy New Year!!!!!!!!!!!
