Automatic action

Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

Suspect a file is incorrectly detected (a False Positive)?

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 detection database 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.

Technical Details

Sadcor is a simple mass mailer that sends itself in Access database files using Outlook. It arrives in emails that looks as follows:

	Subject:	Re: Saddam Corrupted 	Body:		Please find the details of Saddam Corrupted 	Attachment:	account.mdb, win.zip
 

Once the user have received an infected mail and opened attached Access database file, the macro code copies the "account.mdb" to the root of the C: drive. The code also attempts to copy another file, "win.zip" to the root of the C: drive as "win.exe" and "win.zip". After the files have been copied, the worm attempts to execute "C:\win.exe". However, we have not received a copy of this file.

Finally the worm mass mails itself to every recipient in every address book. Beside "access.mdb" the worm attempts to attach "win.zip".

The virus code contains several comments that are never shown to the user.
