Summary
This trojan uses the same vulnerability that JS/Kak and VBS/BubbleBoy to drop itself to the Windows Startup directory.
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
This trojan consists of three different parts: one HTML web page, and two hta files.
The web page is available in an adult site, and it affects Internet Explorer users. Once a user visits that page it immediately drops a file "runme.hta" in the Windows Startup directory and "removeit.hta" in the root of the "C:" drive. Next time when the system is rebooted it executes and changes the Internet Explorer and Netscape Navigator startup page to www.sureseeker.com. It also modifies the Internet Explorer default search pages to that location. These changes are made to the registry, however, the trojan makes backup of these registry settings to two files, "backup1.reg" and "backup2.reg" in the Windows directory.
After that the trojan executes "removeit.hta", that simply deletes "runme.hta" from the Windows Startup directory. On that way the user cannot see the previosly dropped "runme.hta" file.
