Agent.BKY is a worm and a trojan-downloader. It infects .HTML, .PHP and some other files with a small script that points to a website, hosting a file with the recently discovered (March/April 2007) ANI exploit.
The worm also spreads to remote and removable drives, modifies the HOSTS file and downloads more malicious files onto an infected computer. This malware is similar to the worm that we detect as Worm:W32/Anito.A.
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.
