recently i found trojan virus in my home pc. I removed it by virus removal tool. But how can i make sure some one has not installed any keystroke program or spy ware in my system?. and its still running in my computer. I am using lavasoft adaware program and detecting and quarntine it. I beleive certain programs will not be seen in add/remove of windows 2000. but still it will be runing at the back ground. I am scared to use any online purchases because of this. Any comment regarding this is apreciated.

Here is a good program that will help you sort out the programs starting up when you start windows. http://www.hennon.net/modules.php?name=Downloads&d_op=getit&lid=1

Thanks Brad, Let me check it Nikhil

-reformat your PC; like i said in millions of other threads; monitor your activities online safely -avoid any unnecessary websites w/ pop-ups/banners -no matter how much times you run a virus or the latest updates; the viruses that WERE in the PC STILL ARE, but just locked themselves inside your pc

yes I agree with jrIStech , that solution is more fool proof. But we can not restrict going to some sites , otherwise we will be spending more time validating the authenticity of the site. Thanks for the sujesion. Thank u brad its a great tool. I found some exe running , which i uninstalled the application 3 months back. I could stop all this useless exe running . Its a good job. Nikhil
