W32.Downadup.B Virus

Hello Experts Exchange,

I know you prolly have seen this virus elsewhere, but I tried all given methods here at my workplace and none of them seem to work..

The following has been done:

Scan with malwarebytes.org (Found none)
Scan with avast boot scan (Found none)
Disconnect before scanning while scanning
Used Symantec patch method
Used Windows patch method after system update..
Fsecure method

Has anyone have any other tools to get rid of this

Regards,
Mark

One should have good password policy and strong password on network share as well.

keep in mind to use frequently  Bootable antivirus Rescue CD
http://www.techmixer.com/free-bootable-antivirus-rescue-cds-download-list/
Boot-able anti virus Rescue CD method consider as the most effective way to remove the virus, trojan and malware because it track down some viruses, trojans and other malware are embedded so tightly into your operating system that when you boot Windows the normal way. Mostly virus is also loaded and cannot be detected or removed by antivirus software  running in that system. In such a case, booting antivirus rescue CD under clean environment can increase chances to track down virus easily which there no interfere from any windows OS services.

@Madunix

Tried creating a rescue cd via kaspersky but each time it is loaded the beeping noise persist. But when we tried booting another cd it goes in very well..

It cannot be our mother board, neither the optical drive because it loaded successfully when using another boot cd..

Can it be the virus knows of this rescue disk?
