Horty is a worm written in Visual Basic Script.
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 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.

The worm creates its copies in Windows, Windows System and Temp directories respectively kernel32.vbs, alexia.txt.vbs, Natasa.txt.vbs
It also creates copies of itself using the following file names:
c:\x-f**k.TXT.vbs a:\kissme.TXT.vbs b:\kissme.TXT.vbs a:\mydick.TXT.vbs b:\mydick.TXT.vbs a:\drdick.TXT.vbs b:\drdick.TXT.vbs a:\aliens.TXT.vbs b:\aliens.TXT.vbs a:\thebar.TXT.vbs b:\thebar.TXT.vbs a:\ufoxxx.TXT.vbs b:\ufoxxx.TXT.vbs etc.
The worm might sends out 4 times from one infected machine. To do this the virus modifies the registry 'HKLM\SOFTWARE\WUpdat' using its value as a marker.
If the date is 12 of May, the virus shows a message box:
Your PC has been hacked by KaGra[ATZI virus ver 2.1] From the KaGra
If the date is 13 of May, Horty.A tries to delete Windows folder.
