Ptsnoop is a backdoor virus that attaches itself to your PC if it finds active RAS connections on it, if a connection is present it installs itself to a PC or network and copies itself as Ptsnoop.exe in your Windows file (windows\system\directory). Then when you connect to the Internet it will access one of three websites, their addresses are as follows:
http://setway.cjb.net,
http://setway1.cjb.net,
http://setone.cjb.net.
Once a connection is made to one of these websites a hacker or script can take control of your mouse and keyboard. You can find out more about this virus online at
