Guide on how to remove the virus that's spreading through Skype, currently the world's most popular VOIP service. Skype Virus infects computers by sending IM to users with a link to a photo which actually does not exist. After the link is clicked, the worm automatically installs to the computer stealthly. After installation you will not be able to notice anything, but the virus is already sending the same link to your contact list in the background process. It is suspected that the virus does some key logging of user's username and password for email, Facebook, Skype and others. To remove the Skype virus, follow these step by step instructions: Open the Windows Task Manager. To start, press Ctrl-Alt-Del simultaneously. Locate in Processes a file named “mdm.exe.” Click it to highlight and then click End Process. Install a startup program management software like Nirsoft’s WhatInStartup. Run WhatInStartup and look for "Windows Firevall engine" that has reference to "c:/windows/mdm.exe" and delete or disable it. Finally, delete the executable file in directory "c:/windows/mdm.exe" and reboot your computer. To keep your computer safe from viruses and malware at all times, install a very effective anti-virus software like ESET Nod32.
