Exploit:W32/CVE-2011-3402.A is a Generic Detection that identifies malicious files which exploit a known vulnerability in various Windows operating system versions.
Security programs use generic detections that look for broad patterns of code or behavior to identify similar programs or files. If you suspect the file was incorrectly detected, go to: Removal: Suspect a file is incorrectly detected (a False Positive)?.
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.
The malicious files identified by this detection exploit a known vulnerability in specific versions of the Windows opearting system. To prevent successful exploitation, please ensure you install the latest updates available for Windows. A patch for this vulnerability was released by Microsoft in December 2011 and is available at:
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.
Exploit:W32/CVE-2011-3402.A is a generic detection that identifies malicious font files which can be used to exploit a known vulnerability in the TrueType font parsing engine on specific versions of the Windows operating system.
If successfully used, this exploit can allow execution of malicious code contained in specially crafted font data on a web page or Word document.
This exploit is known to be used by malware such as the Cool exploit kit, which is associated with distributing Reveton ransomware, and the Duqu backdoor program.
