If you got Nimda viruses then go to the www.symantec.com site and download the Nimda removal tool from there. The Nimda is really a nuissance. I got it from someone while my computer is connected to the internet but I had neither a browser open nor is my email installed on that machine. My antivirus program did recognized the virus but because it fills the hard drive with itself the anti viral program was constantly killing new created viruses. The only real fix is to get the above program and then disconnect from the internet and run the removal tool. Seravajan
