This trojan uses the same vulnerability that JS/Kak and VBS/BubbleBoy to drop itself to the Windows Startup directory.
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.

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.
To protect yourself against the vulnerability that this trojan uses, you can download and install the patch provided by Microsoft:
