Summary
This trojan has been found to be embedded into web based discussion groups. It uses the scriplet.typelib vulnerability.
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
Variant:Logo.A
Once the user has visited in a web page that contains the trojan, it installs itself to the Windows startup directory as "logo.hta". After that it will be executed when the system is restarted.
When the "logo.hta" is executed, the trojan adds four links to user's Favorites directory and replaces the Internet Explorer start page with a link to an adult site.
Links added to Favorites directory are labeled as follows:
The River Belle Casino, where Lady Luck smiles on you! Send free cards to your friends at nicecards! Real money in your pocket! Welcome to Adult Friend Finder!
Finally the trojan removes itself from the startup directory.
Variant:Logo.B
This variant does not alter the Internet Explorer start page, and the links added to Favorites directory are somewhat different:
INSTANT FREE Submission to 612729 Directories! The River Belle Casino, where Lady Luck smiles on you! Send free cards to your friends at nicecards! Amateur Pages - 600 Free Pics. Welcome to Adult Friend Finder!
