ClamWin was instaled in to my flash memory, when I try to use him, he requesting AV definitions update. I try several times but there is no reply, "main cvd updateing"... how long to wait?

Here's what my PortableClamWin.ini file looks like...

[PortableClamWin]
ClamWinDirectory=PortableClamWin Files\application\bin
DBDirectory=PortableClamWin Files\database
LogDirectory=PortableClamWin Files\logs
QuarantineDirectory=PortableClamWin Files\quarantine
ClamWinExecutable=ClamWin.exe
UpdateExecutable=freshclam.exe
AdditionalParameters=
WaitForClamWin=false
DisableSplashScreen=true

...and the actual locations of my files are as such:

Application: PortableClamWin Files\application\bin
Database: PortableClamWin Files\application\bin\PortableClamWin Files\database

Hi. I always check this site for new goodies and today I found PortableClamWin AV - a virus scanner. I ran it on my flash stick with all the neat portable software on it and it found a virus. Here is the entry that Clamwin AV produced:

E:\PortableVLC\vlc\plugins\libmux_ps_plugin.dll: Trojan.Xombe.HTTP.A FOUND
-- summary --
Known viruses: 51919
Engine version: 0.88.1
Scanned directories: 44
Scanned files: 235
Infected files: 1

I just wanted to let you all know. What is this plugin responsible for? Can I remove it, or do I need to replace it? Thanks in advance.
