EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Popularity Rank: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

Adware.KorAd is an adware infection that has been linked to various symptoms ranging from innocuous or irritating to extremely disruptive. Adware.KorAd can cause pop-up advertisements, browser redirects, and system performance issues. The main goal of Adware.KorAd is to display advertisements on the affected Web browser. Despite the fact that Adware.KorAd is usually associated with a browser toolbar marketed as a useful tool, these types of browser toolbars are usually categorized as PUPs, or Potentially Unwanted Programs, because of the many irritating symptoms typically associated with them. Despite its claims, Adware.KorAd is specifically designed to expose computer users to marketing material and advertisements rather than to provide any type of useful service.
Table of Contents
Why Adware.KorAd and Similar Content May Be Considered Harmful
Adware.KorAd should be removed immediately from the affected Web browser. One of the main reasons for this is that Adware.KorAd and content associated with Adware.KorAd may be installed as a Web browser extension or add-on. Adware.KorAd may spy on your online activity, save data related to your Web browsing habits and history, and then sell this data to marketers or use it to deliver advertisements to your Web browser. These concerns have made PC security researchers become worried about Adware.KorAd and its effects on your computer. It is important to note that any supposed services offered by Adware.KorAd may be found on free alternatives that do not expose your computer to potentially unsafe content or profit at your expense.
What Makes PUPs Like Adware.KorAd Different from Malware
Adware.KorAd is classified as a PUP, meaning that Adware.KorAd is not as threatening or difficult to remove as Trojans or other forms of threats. However, this does not mean that Adware.KorAd's symptoms are any less irritating or disruptive. In fact, a Web browser affected by Adware.KorAd may become nearly impossible to use. This is also especially true because Adware.KorAd may not be installed alone. If Adware.KorAd is installed on your Web browser, it is highly likely that other content similar to Adware.KorAd has been installed on your Web browser as well. This may result in significant system performance issues and a noticeable slowing down of your Internet connection.

Digital Signatures
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good. Malware is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a malware author with no verification). Malware may also be signed by legitimate signatures that have an invalid status, and by signatures from questionable root authorities with fake or misleading “Signer” names.| Signer | Root | Status |

| Irongate Inc | DigiCert Trusted G4 Code Signing RSA4096 SHA384 2021 CA1 | Self Signed |

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- Agent.AITA
