Remove win32.Gimmiv.worm

Remove win32.Gimmiv.worm

Gimmiv worm (also known as Win32/Gimmiv) is a big privacy risk. Gimmiv functions quietly in a background; this helps the worm to steal information, spread further and stay unobserved.

Gimmiv worm employs Microsoft server service remote code execution exploit (MS08-067) to infect other computers. Once it finds systems available for infection, it copies certain files that are able to update themselves from the web.

The purpose of Win32/Gimmiv infection is gathering information about compromised systems and delivering it to remote servers. Gimmiv collects usernames and passwords used on various programs (MSN Messenger, Outlook Express, Internet Exporer, etc); it also makes a list of applications installed on the computer, machine’s name, local machine’s adapder details and Windows version.

Gimmiv connects to the following servers to deliver stolen data and to update itself: summertime.1gokurimu.com, doradora.atzend.com, 59.106.145.58 and perlbody.t35.com.
