Clean MSN Virus is a tool that detects and deletes currently circulating MSN Messenger viruses. For some time now, MSN Messenger has been used to spread viruses. During a conversation, a user receives, apparently from his contact, a link inviting him to open a file that looks like a photo. The file is in fact executable code that contains a virus. Once the user opens the file, the virus runs itself and spreads to everyone on the users contact list. Clean MSN Virus detects more than 4,000 variants of MSN viruses. Clean MSN Virus analyzes active processes in memory and files.
