I just noticed that a recent upgrade of Take Command is reported as being infected with this virus, and an update to NOD in the last few hours added the ability to detect that virus, which is why I became aware of it. In this case, judging by the contents of the article linked to in the answer I accepted, it looks like it is a false positive.
Nevertheless...
Apparently, this virus only runs when an infected program runs, but it then tries to locate a Delphi installation, finds the SysConst.pas file, and adds the necessary code in there to make Delphi compile new programs with the virus in place.
I don't have Delphi installed on this machine, however, so that should at least make this problem a small one here, but at work we have a few machines with Delphi installed. Luckily I don't have Take Command in an updated form my work machine, but whose to say there aren't plenty of other programs out there written in Delphi that people have updated recently...
So, I thought I'd ask. Has anyone seen a live infected SysConst.pas file, and could provide with some sample code that shouldn't be in there? So that we can run through the machines and ensure that we don't have a problem?
