Re: Windows 98 box is 'owned'

This is not an attack...this is a virus that you have on the PC i
think. I have seen this thing before.

Basically what it does is scan all the network for open shares and it
will drop files like that all over the place. People click on them,
they get infected and the cycle starts again. So first thing you want
to do is turn of smb sharing from Windows. That's how it's coming in
probably...

Someone can correct me since this is from memory :)
