What is Sysredirector?

Sysredirector emerges as a perplexing and unwelcome phenomenon for many users, manifesting as a redirect that momentarily takes over the search process, rerouting through sysredirector.com before landing on the intended search results. It often appears without any recent changes made by the user, such as the installation of new extensions, raising questions about its origin and purpose.

The Sysredirector Virus

Sysredirector is indicative of a broader category of software known as browser hijackers. These hijackers, like Search-fine, subtly modify browser settings, redirecting users to specific websites, often for generating advertisement revenue or spreading malware. Despite the benign appearance, the redirection process can lead to significant privacy breaches and the inadvertent download of harmful software.

Is Sysredirector Safe?

The straightforward answer is no. While Sysredirector itself might not directly harm your computer, its presence is a symptom of underlying vulnerabilities, such as malware or malicious browser extensions, which can compromise your personal information and overall system security.

How to Avoid Sysredirector Redirects?

Preventing Sysredirector redirects requires a multi-faceted approach, focusing on the meticulous management of browser extensions and the application of robust security measures.

  • Regularly Update Your Browser and Security Software: Keeping your browser and antivirus software up-to-date is crucial in defending against the latest threats.
  • Monitor and Vet Browser Extensions: Install extensions from reputable sources only. Regularly review and remove any unnecessary or suspicious extensions.
  • Perform Regular System Scans: Use reliable antivirus software to conduct comprehensive system scans, detecting and removing any potential threats.

Sysredirector on Chrome

Chrome users have reported instances of searches being hijacked by Sysredirector, resulting in searches being redirected through unwanted sites. This issue underscores the importance of vigilance in managing extensions and monitoring browser behavior for any anomalies.

Sysredirector on Edge

Edge users are not immune to the Sysredirector dilemma. Reports of searches being rerouted through sysredirector.com before landing on Bing, instead of the desired search engine, highlight the necessity for Edge users to carefully scrutinize installed extensions and employ recommended security practices.


The domain sysredirector.com sits at the heart of this issue, acting as a conduit for redirecting searches to potentially malicious sites. Its presence in your browser’s search process is a glaring red flag indicating the need for immediate action to cleanse your system of related malware or browser hijackers.

Tips for Blocking and Removing Browser Redirects

To combat Sysredirector and similar threats, consider the following strategies:

  • Disable Suspicious Extensions: Access your browser’s extension page (e.g., chrome://extensions/ or edge://extensions/) and disable extensions one by one to identify the culprit.
  • Clean the Windows Registry: For Windows users, checking paths like “HKEY_CURRENT_USER\Software\Microsoft\Edge\Extensions” for unknown extension IDs can help pinpoint and remove rogue extensions.
  • Use Incognito Mode to Test: Running your browser in incognito or private mode can help determine if the issue persists without the influence of extensions or cached data.
  • Consult Security Forums: Online communities and forums can provide valuable insights and solutions from users who have encountered similar issues.


Sysredirector represents a glaring symptom of underlying security vulnerabilities within your browser ecosystem. By understanding its mechanisms and employing strategic countermeasures, users can fortify their digital defenses, ensuring a safer and more secure online experience. Remember, vigilance and proactive measures are your best allies against the myriad of threats lurking in the digital domain.

Step1 Uninstall the Sysredirector app and kill its processes

The first thing you must try to do is look for any sketchy installs on your computer and uninstall anything you think may come from Sysredirector. After that, you’ll also need to get rid of any processes that may be related to the unwanted app by searching for them in the Task Manager.

Note that sometimes an app, especially a rogue one, may ask you to install something else or keep some of its data (such as settings files) on your PC – never agree to that when trying to delete a potentially rogue software. You need to make sure that everything is removed from your PC to get rid of the malware. Also, if you aren’t allowed to go through with the uninstallation, proceed with the guide, and try again after you’ve completed everything else.

  • Uninstalling the rogue app
  • Killing any rogue processes

Type Apps & Features in the Start Menu, open the first result, sort the list of apps by date, and look for suspicious recently installed entries.

Click on anything you think could be linked to Sysredirector, then select uninstall, and follow the prompts to delete the app.
