The Brontok worm is a parasite that spreads across internet by sending infected email attachments to potential host systems. Usually, the message contained in these emails is an offer to check out a particular photo, contained in the “Photo.zip” archive attachment.
Your capabilities to remove the Brontok worm will be disabled immediately after infection, as the parasite will modify your registry entries and security settings. It can also shut down your anti-virus software, which speaks nothing but danger to your system. Be sure not to open suspicious email attachments, especially those with “Photo.zip” names on them.
