Summary
Worm:W32/Rimecud spreads copies of itself to new victims using the infected machine's resources. Rimecud variants may also install a backdoor onto an infected machine that allows a remote attacker to control the affected machine.
Removal
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.
Technical Details
Worm:W32/Rimecud is a large family of worms that typically spread via email, over removable drives (usually by misusing the Windows Autorun function to infect connected USB drives) and over instant messaging (IM) networks.
Once present on a system, Rimecud will create copies of itself and distribute the copies to new victims, either by sending them out as attachments to email messages, in infected removable drives or via IM networks.
Some Rimecud variants also install a backdoor program onto an infected machine that allows a remote attacker to access and control the system.
