An object that takes advantage of a vulnerability to gain unauthorized access or control of a program, device or service.


Automatic action

Once detected, the F-Secure security product will automatically handle a harmful program or file by either deleting or renaming it.

Manually cleaning temporary or cache folders

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:

Exclude a known safe 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.

Technical Details

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:

Vulnerability protection

Note that some exploit detection names indicate the vulnerability involved, such as:

  • Exploit.Java.CVE-2012-0507

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:

Exploit prevention

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.
