pbudsara.exe NEW VIRUS ??

Avast has found a virus entitled “pbudsara.exe” which apparently originated from China (see link)

http://www.threatexpert.com/report.aspx?md5=f87ea91860680a40fe4f481ded44a4da

And the virus passes through every computer on a network, Trojan’s onto ever HDD and into the computer’s registry.

PROBLEM, Avast finds it and asks me if I want to delete it and/or put it in the vault and I have tried both processes and yet the virus is still there and on doing a search in Windows for the viruses name and nothing comes up. However, I clear the vault or delete the virus via Avast then when I’m all done, reboot the computer and do another full scan or even just scan the discs individual via the right click “Scan” method and either way the virus keeps coming up found.

Please help as it has now infected everyone’s computer on our network (5 altogether).

Thanks in advance for any and all who respond.

First is it possible to isolate the computers on the network ? As this will require a clean one at a time approach

To ensure that I get all the information this log will need to be uploaded to Mediafire and post the sharing link.
