NiceHello is an email worm which uses MSN Messenger contact list to collect email addresses. The worm steals the user's MSN personal login information and sends it to a predefined email address to the virus writer.
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.
NiceHello collects email addresses from the user's MSN Messenger contact list. Using its own SMTP engine it sends infected messages to those addresses.
The worm has several hardcoded messages that it sends with the infected attachment.

When the worm is run on a clean computer it copies itself to one of the following directories according to Windows version:
'c:\windows\system' 'c:\winnt\system32'
This copy of the worm is then added to the registry as
'HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\System 64 Driver for Games'
so the worm will be run when Windows starts.
