Trojan:W32/Crypt.O

So far, we found the only reliable way to delete this intrusive adware is to boot from Windows installation CD to Recovery Console and to delete the malicious DLL file from a hard disk. Alternatively you can use ERD commander or a bootable Linux CD to access your NTFS partition and to delete the DLL file. If you have F-Secure Anti-Virus, select 'Rename Automatically' disinfection action for the On-Access Scanner (OAS) and reboot the computer. FSAV should rename the DLL file before it becomes active.
