Exploit:W32/CVE-2010-0188.C identifies malicious PDF files downloaded by the Blackhole exploit kit that exploit a known vulnerability.
The malicious PDF files target a known vulnerability in Adobe Reader; to prevent successful exploitation, please ensure you install the latest updates available for Reader and/or remove any old, unnecessary installations.
To ensure you have the latest version of Reader, please refer to the vendor's product page.
Security programs will sometimes unintentionally identify a clean program or file as malicious if its code or behavior is similar to a known harmful program or file. This is known as a False Alarm or False Positive (FP).
In most cases, a False Positive is fixed in a subsequent database release.
Usually, updating your F-Secure security product to use the latest database is enough to resolve the issue.
If you suspect a detected file is a False Positive, you can check by first updating your F-Secure security product to use the latest detection database updates, then rescanning the file.
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it to F-Secure Labs for re-analysis.
NOTE If the file was moved to quarantine, you will need to first collect the file from quarantine before you can submit it.
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.
Microsoft also provides enterprise-level instructions for excluding files from scanning by antivirus software.

The exploit file is delivered by the highly-prevalent Blackhole exploit kit, a utility program used by attackers to silently install their malware onto a user's computer during a drive-by download attack.
The exploit kit is typically hosted on a short-lived webpage, and victims are driven to these pages by either hijacking traffic from a legitimate, compromised website, by redirecting traffic from search engines using Search Engine Optimization (SEO) poisoning, or through malicious links in spam emails.
Once a visitor is on the malicious page, the exploit kit silently probes the visitor's computer system for vulnerabilities in specific applications (in some cases, specific versions of these applications). Targeted applications include Java Runtime Environment, Media Player, Adobe Flash Player and Adobe Reader, and specific Windows components.
If found, the kit automatically exploits the vulnerabilities and downloads additional files (the kit's payload) onto the victim machine. The files downloaded by Blackhole onto the victim machine are usually other known malware, including:
