What is McAfee Webadvisor ?

McAfee WebAdvisor is a browser add-on available for popular browsers like Chrome and Firefox. It provides users with warnings and safety ratings for websites, helping to protect against potential threats such as malware and phishing attempts. However, there are instances where rogue software can hijack the WebAdvisor extension, leading to issues on your PC. If you’re experiencing problems with McAfee WebAdvisor, it’s possible that a browser hijacker has taken control of the app. However, if you have the WebAdvisor extension installed but don’t notice any unusual symptoms or disruptions while browsing, it’s likely that you’re not dealing with a hijacker, and there’s no immediate action required. The genuine WebAdvisor app developed by McAfee is legitimate and shouldn’t cause any problems on your system.

How to uninstall McAfee Webadvisor?

If you’re receiving persistent malware warnings on your computer that prompt you to install a security tool, it’s advisable not to trust those warnings and instead uninstall McAfee Webadvisor. These warnings are often false positives designed to deceive users into purchasing unnecessary security tools. If you already have a legitimate security program installed and it doesn’t detect any issues on your computer, it’s best to disregard these random warnings and focus on identifying and removing their source. This source could be a program imitating the McAfee Webadvisor app or another program altogether. In either case, the guide provided below will assist you to uninstall McAfee Webadvisor and completely removing it from your PC.

McAfee WebAdvisor on Chrome

When using McAfee WebAdvisor on Chrome, encountering a warning about “Windows WebAdvisor Viruses found” can have two possibilities. It could be a legitimate warning from the McAfee WebAdvisor on Chrome extension, indicating potential malware on a webpage you are about to visit. In this case, it is advisable to trust the warning and avoid visiting the flagged page unless you are confident it is safe. On the other hand, the warning could be a fake positive triggered by a deceptive rogue app. If you are experiencing other suspicious symptoms on your PC, such as intrusive ads or system slowdowns, it is likely a fake warning. In such cases, it is important to be cautious and not be misled by false alerts.

We strongly recommend completing the removal process of McAfee WebAdvisor only after reading the following detailed instructions.

Detailed Mcafee WebAdvisor Uninstall Instructions

Step 1

Quit the Internet connection of your PC to prevent the McAfee WebAdvisor hijacker from interrupting you during the removal process. To have access to this page, we recommend opening it on your phone or on another device that’s connected to the Internet.

Step 2


From the Start Menu, go to the Control Panel of your PC, then select the Uninstall a Program section, and search for any program that may be linked to the hijacker. To make the search easier, sort the entries in the list by installation date so that the most recently installed ones would be grouped together.

McAfee WebAdvisor uninstall via Control Panel

If a potentially rogue/unwanted program is found, right-click it, select Uninstall, and follow the prompts (if there are any prompts) to complete the installation. If there’s an uninstallation wizard, pick the removal settings that would ensure the full deletion of everything linked to that program.

In case you are unable to perform the McAfee WebAdvisor uninstallation at the moment, try once again after the completion of the other steps.

Step 3

Press Ctrl + Shift + Esc and then click Processes in the Task Manager window that appears. Look for anything named McAfee WebAdvisor or anything similar and if you come across such an entry, right-click its name, open the File Location of the process, return to the Task Manager, right-click the process again, and End it. After that, go back to the file location folder that you opened and delete it together with all of its files and subfolders.

Also, look for other sketchy-looking processes and for processes that have the same name as the program from the previous step (the one you tried to delete). If you find anything, first search for it online to see if there are reports from security experts confirming that the process is rogue. Also, scan the files that are stored in the location folder of the process using the free scanner provided below – this will let you figure out if the suspected process (processes) is truly unwanted/rogue.

    Step 4

    Now it’s time to put your PC in Safe Mode by following the instructions from the linked page. The reason your PC should be in Safe Mode for the next step is to prevent the hijacker from launching its processes again (in Safe Mode, only essential system processes are allowed to start automatically).

    Step 5

    In this step, you will have to visit several types of system settings, check them for changes caused by the hijacker, and revoke those changes. To do this, use the search bar in the Start Menu to find the items listed below, open then, and then perform the respective instructions provided for each of those items:

    Msconfig – In the System Configuration window, go to Startup and click on Open Task Manager (if you are using Windows 7, you don’t need to click on anything). When you see the startup items listed on your screen, remove the ticks from the checkboxes of the ones you don’t trust or recognize, and then select  OK.

    Undo DNS changes made by McAfee WebAdvisor

    Task Scheduler – Once the Task Scheduler opens, select the top-most folder (Task Scheduler Library) from the upper-left corner, then look at the tasks, and delete anything that seems potentially linked to the McAfee WebAdvisor hijacker.

    Delete McAfee WebAdvisor scheduled tasks

    Services.msc – In the Services window, search for entries named McAfee WebAdvisor or anything similar and if you find any, right-click them, go to their Properties, and there change their Startup types to Disabled.

    Disable McAfee WebAdvisor services

    notepad %windir%/system32/Drivers/etc/host – After the Hosts notepad file opens, scroll down towards the end of its text, check if there are any lines written underneath the two “Localhost” lines, and if there are, copy-paste them in the comments section below this post. Someone from our team will soon let you know if the lines you’ve sent us are related to the hijacker, in which case you’d need to delete them from the file.

    Delete McAfee WebAdvisor IPs from Hosts

    Regedit.exe – When Windows asks you for your Admin permission, click Yes to provide your confirmation, and then, when the Registry Editor shows up, click the Edit menu and select Find. In the Find window, type WebAdvisor, click the Find Next button, and if the search finds a related item, delete that item and perform another search for McAfee WebAdvisor. In this way, you must ensure that all Registry items related to McAfee WebAdvisor get deleted, after which you must navigate to these next three Registry locations by using the left panel of the Registry Editor.

    Clear the Registry from McAfee WebAdvisor items
    • HKEY_CURRENT_USER/Software/Random Directory
    • HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run
    • HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main

    Next, look in all three of those locations for any items that seem out of place – for instance, once that have suspiciously-long names and/or names that seem to have been randomly generated (something like this “e903j2td90f4gh98ur309djfht20r3e” for instance). Let us know in the comments should you come across such items, but don’t delete them unless we confirm that they need to be removed from the Registry.

    Step 6

    Finally, it is time to clean your browsers – start by opening your main browser, selecting its menu (should be in the top-right or top-left corner), and opening the Extensions/Add-ons section. In Chrome and some other Chromium-based browsers, you must first select the More Tools sub-menu to see the Extensions button.

    Once you are at the Extensions section, your job is to Disable and then Uninstall the rogue McAfee WebAdvisor hijacker extension as well as any other browser extensions that seem undesirable or untrusted.

    Disable and then Uninstall the rogue McAfee WebAdvisor

    After you are done with this, you must select the browser menu again, go to Settings, and there select the Privacy and Security section. If you don’t see a button to open Privacy and Security, first click on Advanced, and it should appear.

    In Privacy and Security, search for a button labeled Clear Data/Choose what to clear, and click it.

    Choose Privacy and Security section to clear McAfee WebAdvisor

    Next, select the Advanced tab in the newly-opened window (if there is such a tab), put ticks in all boxes except the one in front of Passwords, and click Delete/Clear.

    Clear browsing data to remove McAfee WebAdvisor

    Lastly, remember to perform this step for all other browsers on your computer.
