Question:

“As an expert, could you advise on how to eliminate a persistent malware issue in Google Chrome that defaults my browser to UNIX Search? Despite clearing policies and extensions via the registry editor and running both Malwarebytes and ADWCleaner—which identified a TrojanInjector and two potentially unwanted programs (PUPs)—the problem persists. Post-quarantine and removal, Chrome continues to redirect to a Unix page, and both Edge and Chrome indicate they are managed by an organization, a setting I’m unable to change. Would you have any recommendations to resolve this before considering a factory reset?”

Answer:

Step 1: Uninstall and Reinstall the Browsers

– Uninstall both Google Chrome and Microsoft Edge.

– Before reinstalling, restart your computer to clear any active processes related to the browsers.

– Reinstall the browsers from their official websites.

Step 2: Check for Malicious Programs

– Use the Windows Control Panel to look for any recently installed programs that you do not recognize and uninstall them.

– Run a full system scan with an antivirus program different from the ones you’ve already used, as different scanners may detect different threats.

Step 3: Reset Browser Settings

– After reinstalling, use the browsers’ built-in option to reset settings to their original defaults.

• This can often remove residual changes made by malware.

Step 4: Modify Hosts File

– Malware can modify your system’s hosts file to redirect browsers. Check the hosts file for any entries related to UNIX Search and remove them.

• The hosts file is typically located at `C:\Windows\System32\drivers\etc\hosts`.

Step 5: Examine Scheduled Tasks

– Malware can create scheduled tasks to reinfect or modify settings. Open Task Scheduler and look for any tasks that were created around the time the issue started, and delete them if they seem suspicious.

Step 6: Create a New User Profile

– Sometimes, creating a new user profile on your computer can circumvent the settings controlled by malware.

• Transfer your files to the new profile, but be cautious not to transfer any infected files.

Step 7: Seek Professional Help

– If the issue persists, consider taking your computer to a professional who can perform a more in-depth analysis and cleaning.

Step 8: Backup and Factory Reset

– As a last resort, backup your important files (ensuring they are clean of malware) and perform a factory reset.

• A factory reset will remove all data and programs, so it should only be done after all other options have been exhausted.

Remember,

the key to preventing malware infections is regular system maintenance, cautious browsing habits, and keeping all software up-to-date. Implementing these practices can significantly reduce the risk of future infections.
