A website that provides emoticons for Skype, the popular internet phone and video chat service has been flagged as malicious.
Users are being tempted to download the emoticons by emails informing them of the new Skype emoticons. However, visitors to the website could find their machines infected with a virus identified as Win32/Virut.BN. This virus could potentially steal identity information or do other forms of damage to a computer. The virus targets .EXE and .SCR Windows files. .SCR Windows files are typically screen savers for Windows. .EXE files are executable files used to perform various operations on a computer. They can only be read by a computer. This virus also opens a backdoor by connecting to an Internet Relay Chat server, allowing a remote attacker to download and execute arbitrary files on the infected computer.
Have you recently downloaded Skype Emoticons? What should you do?
The threat is rated as severe. If you have downloaded Skype emoticons run a full system anti-virus scan. However, that said, the method of infection used by Win32/Virut can damage some infected files beyond repair. In these cases, in order to return a machine to its pre-infected state, it may be necessary to install a clean backup of the operating system and associated applications.
