Email-Worm:W32/Runouce is distributed in infectious executable email attachments.
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.
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.
When run it copies itself to the System Directory as Runouce.exe and modifies Windows Registry so that the copy in the direcorty is run each time Windows starts.
Searches for HTML files in the users' hard drive and modifies them to launch the file README.EML, created in the same directory where the HTML is found.
To propagate itself, Runouce creates email messages with the following format:
Subject: [text, followed by "is comming!"] From: [The sender address pretends to be one from yahoo.com]
The worm spreads itself as an attachment named pp.exe with MIME type audio/x-wav.
It uses a static server to send messages through its own SMTP engine.
