What Is Trojan.Blocker.B?
Trojan.Blocker.B is a type of Trojan horse, a malicious program that disguises itself as a legitimate application. Once installed, it can allow unauthorized access to your system, steal sensitive information, and disrupt your computer's operation. The name "Trojan.Blocker.B" suggests that it may be designed to block or interfere with certain system functions or security software, but the exact nature of this threat can vary.
How Trojan.Blocker.B Operates
Trojan.Blocker.B, like other Trojans, operates by exploiting vulnerabilities in your system or tricking you into installing it. It may be disguised as a useful program or hidden within another application. Once installed, it can communicate with its creators, allowing them to control your system remotely, steal data, or install additional malware. The specific actions of Trojan.Blocker.B can depend on its design and the intentions of its creators.
Symptoms of Infection
The symptoms of a Trojan.Blocker.B infection can vary but may include slow system performance, frequent crashes, unexpected pop-ups, and changes to your system settings without your consent. You might also notice that your antivirus software or firewall has been disabled, or that certain programs or functions are blocked. In some cases, the infection might not display obvious symptoms, making it harder to detect without a thorough system scan.
How to Remove Trojan.Blocker.B
- Boot your computer in Safe Mode with Networking to limit the malware's ability to interfere with the removal process.
- Use a reputable anti-malware tool, such as SpyHunter, to perform a full scan of your system. This can help identify and remove all components of the Trojan.
- Uninstall any suspicious programs that you do not recognize or that were installed around the time the infection was detected.
- Reset your web browsers (Chrome, Firefox, Edge) to their default settings to remove any malicious extensions or settings changes made by the Trojan.
- Reboot your computer and perform another full scan with your anti-malware tool to ensure that all remnants of the malware have been removed.
Conclusion
Removing Trojan.Blocker.B requires careful and thorough action to ensure that your system is completely cleaned and protected against future infections.

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.AIAH
