The detection of Worm.RunOnce indicates that your system has been compromised by a type of malicious software known as a worm. This type of malware is designed to replicate itself and spread to other systems, often without the need for user interaction. Worms can cause a range of problems, from slowing down your system to stealing sensitive information. In this report, we will provide an overview of Worm.RunOnce, how it operates, the symptoms of infection, and steps you can take to remove it from your system.
Table of Contents
What Is Worm.RunOnce?
Worm.RunOnce is a type of worm that is designed to run once on a system and then replicate itself. The exact nature and behavior of Worm.RunOnce are not well understood, as it is a relatively generic detection name. However, it is clear that it is a type of malware that can cause significant problems for infected systems. Worms like Worm.RunOnce often exploit vulnerabilities in operating systems or applications to spread, and can be introduced to a system through a variety of means, including email attachments, infected software downloads, or exploited vulnerabilities.
How Worm.RunOnce Operates
Worms like Worm.RunOnce typically operate by exploiting vulnerabilities in a system or application to gain access and then replicate themselves. They can spread through a network, infecting other systems and causing a range of problems. Worms can also be used to install additional malware, such as Trojans or spyware, which can steal sensitive information or give an attacker control over the infected system. The exact mechanisms used by Worm.RunOnce are not well understood, but it is likely that it uses a combination of social engineering tactics and exploits to spread.
Symptoms of Infection
The symptoms of a Worm.RunOnce infection can vary, but common indicators include slow system performance, unexpected changes to system settings, and unexplained network activity. Infected systems may also exhibit unusual behavior, such as crashing or freezing frequently. In some cases, the presence of a worm like Worm.RunOnce may not be immediately apparent, as it may be designed to operate stealthily and avoid detection.
- Slow system performance
- Unexpected changes to system settings
- Unexplained network activity
- Unusual system behavior, such as crashing or freezing
How to Remove Worm.RunOnce
- Boot your system into Safe Mode with Networking to prevent the worm from spreading and to give you access to the internet.
- Use a reputable anti-malware tool, such as SpyHunter, to perform a full scan of your system and remove any detected threats.
- Uninstall any suspicious programs that may be related to the infection.
- Reset your web browsers, including Chrome, Firefox, and Edge, to their default settings to remove any malicious extensions or settings.
- Reboot your system and perform another scan to ensure that the worm has been fully removed.
Conclusion
Worm.RunOnce is a type of malware that can cause significant problems for infected systems. By understanding how it operates and the symptoms of infection, you can take steps to remove it from your system and prevent future infections. It is essential to use a reputable anti-malware tool and to follow best practices for system security, such as keeping your operating system and applications up to date and avoiding suspicious downloads or email attachments. By taking these steps, you can help protect your system from the threats posed by Worm.RunOnce and other types of malware.

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 |

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.DSS
