Summary
On January 24th and 25th, 2004, a number of emails with a fake virus warning from Microsoft were spammed. When users view the email it attempts to download and execute a variant of VBS/Inor trojan dropper from a web site. The real address has been spoofed using a security vulnerability in Internet Explorer.
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
When an user opens the spammed email, an attept to download and execute a VBS/Inor dropper is made. If the dropper is able to execute, then a variant of W32/Dumaru worm is installed into system. Inor drops the worm to "C:\2.exe".
We have received reports that different variants of W32/Dumaru have been dropped from the web site. Further information about W32/Dumaru is available within the following descriptions:
