Click on the "startup" tab. See if that cryptic filename is listed anywhere.
Do you have Spybot Search and Destroy? (You should) If you find that entry, enable expert mode in "mode" and make sure Startup List is checked in the right pane. In the left pane, click on Startup list, and see if it's there. Then click the bar on the right bottom and see if there's any info about it. If you contact F-Secure and find out it's not theirs, you can remove it from here by selecting it and clicking the Delete above.
If you aren't using other spyware programs, like AdAware Personal and Javacool's Spyware Blaster (don't accept substitutes!) it would be a good idea to use them. And you could post a Hijack log in the HijackThis forum

When a program that has been installed (like malware, for instance) is removed, there may still be an entry in the Startup list and when you boot up you'll get an error message that the necessary file can't be found. Yesterday, I removed a Soundblaster card from my PC and on bootup I got "error: p17.dll can't be found." Sure enough, there was an entry in the Startup list that hadn't been removed with the software, and it was from Soundblaster and Audigy cards.
