Today’s roundup of virus alerts:

OF97/Exedrop-C – A Microsoft Office virus that drops an unnamed Trojan horse on the infected machine. (Sophos)

W32/Agobot-IY – An Agobot variant that spreads via network shares and uses IRC to provide backdoor access to the infected machine. The virus installs itself as “DVRCONF.EXE” in the Windows System directory and disables certain security applications. It can be used to sniff for passwords and launch denial-of-service attacks against remote sites. (Sophos)

W32/Bobax-C – This Bobax variant exploits the same Microsoft Windows LSASS vulnerability as the Sasser worm. It’s main function is to act as a mail relay for sending spam. (Sophos)

Troj/Dloader-IU – According to Sophos, “Troj/Dloader-IU is a downloader Trojan that copies a file from the website to a file in the Windows system folder named TMPFLE.EXE and executes it.” (Sophos)

Kibuv.A – Like Bobax, Kibuv imitates the Sasser worm by exploiting the LSASS vulnerability in Windows. No word on what damage this miscreant can cause. (Panda Software)
