Typical of some of the Av companies.. Sysmantec have just discovered Version K of the Lovgate Worm.. As it is a threat as a network aware worm, and not the only one, it is important for those not familure to follow the advice given..
Most Importantly.. Only share the folders that are needed .. and No Extra's.. And If it dosen't impead your software, place passwords for any kind of Write access to the folders that are shared:

Here is the guff from Symantec

Wild: Low
Damage: Medium
Distribution: High

W32.HLLW.Lovgate.K@mm is a variant of W32.HLLW.Lovgate.I@mm. It has been repacked to make it difficult for existing antivirus software to detect.

W32.HLLW.Lovgate.K@mm is also a mass-mailing worm that attempts to email itself to all the email addresses it finds in the files whose extensions start with "ht." The subject and attachment of the incoming email are chosen from a predetermined list.

W32.HLLW.Lovgate.K@mm attempts to copy itself to all the computers on a local network, and then infect those computers. The worm also has Backdoor Trojan capabilities. By default, the Trojan component listens on port 10168.

If the infected computer runs Windows NT, 2000, or XP, the worm will attempt to disguise itself as the normal Windows process, "LSASS.EXE."

This threat is written in the C++ programming language and is compressed several times with ASPack.
