Description:
Win32.VkHost drops a file to the users application directory. Once run it infects the hosts file and redirects specific russian websites to remote IP-adresses.
Removal Instructions:

Files:

Please use Windows Explorer or another file manager of your choice to locate and delete these files.

The file at "<$SYSDIR>\drivers\etc\hosts".
You may need to move the file "<$SYSDIR>\drivers\etc\hosts" to "<$SYSDIR>\drivers\etc\hosts_infected".
Make sure you set your file manager to display hidden and system files. If Win32.VkHost uses rootkit technologies, use our RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!

Important: There are more files that cannot be safely described in simple words. Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd) to remove them.

Hosts:

The host file is a local address book for Internet pages. It is sometimes used by malware to block certain domains, or to silently redirect them.
Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd) or RunAlyzer (http://www.safer-networking.org/index.php?page=runalyzer) will show its content to you; you can also us a text editor to locate and edit the file "hosts" (most likely in C:\Windows\System32\drivers\etc\).

Check the hosts file entry for the domain "*".
