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.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

• Check for the latest database updates

  First, check if your F-Secure security program is using the latest updates, then try scanning the file again.

• Submit a sample

  After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

  Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

• Exclude a file from further scanning

  If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

  Note: You need administrative rights to change the settings.
