In some cases, an infected file, or archive file containing infected files, is detected inside a temporary or cache folder. For instructions on dealing with such an infection, see:
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 Positive. 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. 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.

In computer security terms, an exploit is an object - a program, a piece of code, or even just a string of characters - that takes advantage of a vulnerability in a program or operating system to gain unauthorized access or control of a program, device or service.
An exploit is almost always used in a malicious context.
Exploits are often incorporated into individual harmful programs such as trojans or worms, to facilitate their other destructive actions. These harmful programs are most commonly spread via email attachments, or as disguised files that are distributed over networks.
Exploits are also commoditized as part of the 'arsenal' of an exploit kit. Users most commonly encounter exploit kits when they view a webpage secretly hosts the kit. While the page is being viewed, the kit silently probes the user's computer for any flaws that can be leveraged by one of the exploits in its arsenal.
Exploits allow an attacker to perform a wide range of possible actions on an affected device, from viewing data on a restricted-user database to gaining almost complete control of a compromised system.
For examples of exploits on various platfoms, see the following descriptions:
Note that some exploit detection names indicate the vulnerability involved, such as:
Where CVE-2012-0507 is the name used by the CVE - Common Vulnerabilities and Exposures (CVE) organization to identify the specific vulnerability targeted by the exploit.
Further information on the most common vulnerabilities found in most programs may be found at:
The vulnerabilities leveraged by the exploits are usually application or platform specific; in other words, a specific program (or even a specific version of a particular program) must be installed on the machine in order for the exploit to be effective.
To prevent exploitation of such vulnerabilities, please refer to the application vendor for the latest updates and additional advice.
