Virus infected - cannot install antivirus "the system administrator has set policies to prevent this installation"

(Searched the knowledgebase but didn't find the solution).

I have a colleague's laptop which is infected with the Antivirus XP 2008 spyware and the Gaggle.D/Israfel.vbs worm (and probably a lot more too - they didn't have AV on the laptop and downloaded from internet).

The error message "the system administrator has set policies to prevent this installation" is preventing me from installing an AV package as well as opening the registry editor. This is so in Safe Mode as well as the Safe Mode administrator. As its XP Home there isn't the gpedit.msc snap-in and I'm hitting a brick wall.

Any help appreciated.

There are probably several things that are causing this.

The virus likely has injected .dll's into system processes, and there is a good chance that that the machine has a root kit as well.  Either of these could be actively monitoring the system for attempted installations of antivirus software, and be preventing it from being installed.

Can you try to run HijackThis and rootkit revealer, and post the logs?

I agree with russell124 in getting those logs. I would also run MalwareBytes' Anti-Malware as it removes AV2008 nicely.

Let it fix whatever if finds. Let us know how you make out.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I would remove the harddrive and install it in a protected machine and then Run a scan with Malwarebytes on the drive as suggested above Along with an antivirus program like Kaspersky.

Thanks to your help, I've been able to remove the offending services which messed up the security policies and registry entries, prevented me installing AV software and opening the Registry Editor. Kaspersky is now disinfecting (2519 files so far of an email worm).
Many thanks.
