Virkel is a backdoor with IM (Instant Messenger) spreading capabilities. It was first found on October 26th, 2005. The backdoor can provide a hacker with information about a system, work as a proxy, update itself, perform a Denial of Service (DoS) attack, open remote shell, download files. It also kills processes of anti-virus and security software and blocks access to many different sites that belong to anti-virus and security software vendors.
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.
