I have a server running Windows 2003 Server R2 that was making unauthorized connection attempts to various addresses on the internet. I used Malwarebytes and SuperAntiSpyware to scan and remove (I think) everything while in "Safe Mode with Networking". Although all subsequent full scans using Malwarebytes and SuperAntispyware have been clean, I found an item in a hijackthis.log that seemed suspicious:

"O23 - Service: Uninterruptible Pouirw (Windows Managemuirw) - Unknown owner - C:\WINDOWS\svchosm.exe"

Searching for the file name doesn't turn up anything, nor does listing the directory.
