Is TabMemoryOptimizer ads dangerous?

From our report of Oct 2021 · not reviewed since

TabMemoryOptimizer promises to reduce the load on memory but also produces ads

TabMemoryOptimizer is a browser extension that may seem helpful initially - its primary function is to supposedly reduce the memory usage of a computer by freezing the unused browser tabs; this should also allegedly improve web browsing performance and speed. However, this application has plenty of negative characteristics and is commonly categorized as adware , making users' online time much less secure.

As soon as the app is installed on the system, it changes the way Google Chrome operates. Initially, there are no major differences observed by users, although this quickly changes after they start browsing the web. As long as the TabMemoryOptimizer extension is installed on the system, it will produce ads and even redirects to websites that promote scams.

As a result, people might be exposed to potentially dangerous content and end up installing other potentially unwanted programs or even malware. Personal information disclosure can also occur if users are redirected to a phishing website. Users might also be tricked into subscribing to services or contracts that are completely useless, which would result in unexpected financial losses.

The deceptive features

It is not a secret that Google Chrom is notorious for its extensive resource usage, especially when many tabs are opened.

This is why so many people might find TabMemoryOptimizer appealing - it is supposed to reduce memory usage by freezing background browser tabs. Indeed, the description of the app sounds promising:

However, this function comes at the cost of a compromised web browser experience and even computer security. As soon as users start browsing the web, they might notice that their browser is not behaving as usual. There are several negatives aspects that they might come across:

While advertisements are legitimate for monetization, applications that insert ads everywhere and engage in aggressive redirect tendencies are considered malicious. To make matters worse, these ads are usually of malicious content. For example, people might be shown fake antivirus scan results, implying the system is infected with malware.

This can make some less experienced computer users believe that something is very wrong, and they might panic; the purpose of such fake messages is to make people download less than secure software. In fact, it is one of the main malware distribution methods.

Security software is the best way of dealing with malware and all its components.

  • Pop-up ads show up on most visited websites;
  • Redirects can occur abruptly;
  • New tabs opened at ransom times.

How TabMemoryOptimizer ads got into your browser

From our report of Oct 2021 · not reviewed since

TabMemoryOptimizer extension can be downloaded on the official Google Web Store website, although there are plenty of third-party sites that are used for its distribution.

Users typically install new browser extensions and applications from either official sources or third-party websites. They look for certain functionality - file converters, video players, adblockers, system optimizers, and much more.

Even though many such apps can indeed be useful, some of them have additional functions that might only be visible after installation, and they are not positive ones. In this case, people might be tempted by the reduced resource consumption while using their browsers.

Whenever you encounter an app that you have never heard of, you should first check some reviews online and not just blindly install it. Unfortunately, some people might end up installing the app without even realizing it - this commonly happens thanks to software bundling packages, where several additional components are inserted into one installer.

Thus, you should be careful when installing new applications on your PC, especially when they come from third-party websites. Take your time reading the installation instructions carefully, pick Advanced/Custom settings to stay in control, remove all ticks from pre-ticked boxes, and decline all the offers on the way (watch out for button placements).

How to remove TabMemoryOptimizer ads

How to remove the TabMemoryOptimizer extension

Do the browser steps in every browser and profile on the PC, then check Windows for the program that installed the extension.

  1. Step 1: Remove extensions you did not add

    TabMemoryOptimizer often works through an extension, so go through the extension list of each browser:

    • chrome://extensions
    • edge://extensions
    • Extensions and themes in Firefox

    Switch suspicious extensions off one at a time and reload the page where the problem shows, then remove the one that stops it, and any other you did not add.

    Remember the other browsers and profiles on the PC. If Remove is missing or greyed out, a policy forces the extension, which the policy step deals with. Windows 11 and Windows 10 show the same pages.

    Chrome menu with Extensions and Manage extensions highlighted
    Chrome on Windows 11: More > Extensions > Manage extensions.

  2. Step 2: Uninstall TabMemoryOptimizer

    Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10. Sort the list by install date and find TabMemoryOptimizer, then choose Uninstall from the three-dot menu next to it (in Windows 10, click the entry and then Uninstall).

    Remove anything else installed on the same day that you do not recognise, because such programs usually arrive together in one installer. If the uninstaller opens a browser page with an offer or a survey, close it: the program is removed either way.

  3. Step 3: Reset the browser

    Finish the browser part with a reset, which puts the search engine, start page, new tab page and site permissions back to their defaults and switches extensions off. Chrome: Settings > Reset settings > Restore settings to their original defaults.

    Edge: Settings > Reset settings. Firefox: Help > More troubleshooting information > Refresh Firefox, which also removes its extensions. Your bookmarks and saved passwords are kept, and the menus are the same on Windows 11 and Windows 10.

    Chrome Settings page with the Reset settings section open
    Chrome on Windows 11: Settings > Reset settings.

  4. Step 4: Scan the PC, then run the offline scan

    Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.

    Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online.

One of the basic means to add a layer of security - choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features.

However, if you want true anonymity, we suggest you employ a powerful VPN - it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable.

Family photos, work documents, school projects - these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur:

  • power cuts
  • Blue Screen of Death errors
  • hardware failures
  • crypto-malware attack
  • even accidental deletion

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, can be your only hope to retrieve your invaluable files.

Remove TabMemoryOptimizer

It goes without saying that potentially unwanted programs, especially adware, should not be welcomed on any user's computer.

Not only does it commonly fail to provide quality features that would work, but also compromise people's web browsing experience by inserting ads into all visited websites. Nobody likes ads, although most users can tolerate them as long as they are not intrusive or malicious. Unfortunately, that's not something you could say about adware.

Since it is a browser extension, you need to access the settings and uninstall the unwanted app as follows:

MS Edge (Chromium)

MS Edge (legacy)

However, removing browser extensions is not enough, and you should take your time cleaning your browsers properly. Otherwise, the tracking activities and unwanted ads might show up as well. For a quick solution to remove cookies, caches, and other web data, you can use .

The tool can also fix the damage done to system files and serves as a great complementary application to your security software. If you want to do it manually, follow these steps:

MS Edge (Chromium)

MS Edge (legacy)

Keep in mind that there could be other unwanted browser extensions or applications installed on your system. The easiest way to check is by using security software, although if you are completely sure which apps you have recently installed and they are causing the unwanted browser behavior, you can get rid of them as per usual.

  • Open Google Chrome, click on the Menu (three vertical dots at the top-right corner) and select More tools > Extensions.
  • In the newly opened window, you will see all the installed extensions. Uninstall all the suspicious plugins that might be related to the unwanted program by clicking Remove.

Questions about TabMemoryOptimizer ads

What is TabMemoryOptimizer and why is it on my PC?

TabMemoryOptimizer is a program that was installed on the PC, most likely together with something else you downloaded. Free software sites and many installers add extra programs on setup pages with pre-ticked boxes, so the extra install looks like your choice even though nobody read the page.

Check the install date in Settings, Apps, Installed apps: the program you installed that day is the probable carrier. If you do not need TabMemoryOptimizer, uninstall it. If it belongs to your hardware or to a program you use, search its exact name and publisher first, because drivers and their tools can have unfamiliar names.

TabMemoryOptimizer came back after I uninstalled it. Why?

Something else is reinstalling it. Common causes are a second program from the same publisher, a scheduled task that downloads it again, or a browser extension that keeps prompting for it. Sort Installed apps by install date and uninstall each entry from the same day that you did not choose.

Then open Task Scheduler and look in the Task Scheduler Library for tasks with updater-style names that you do not recognise. Check Startup apps in Task Manager too. If TabMemoryOptimizer still returns, start Windows in Safe Mode, uninstall it there and run a Microsoft Defender offline scan, which looks for loaders that ordinary scans can miss.

Did TabMemoryOptimizer collect my data?

Adware typically collects what it needs to choose ads:

  • the sites you visit
  • search terms
  • approximate location
  • browser and system details

Extensions with permission to read and change data on all websites can technically see everything on those pages, including forms. That is a privacy problem rather than proof of theft.

If you typed card details or passwords while it was active, changing the most important passwords is a reasonable precaution. Clearing cookies after removal ends the tracking sessions it may have started.

Why is my browser so slow since the ads started?

Each page now does extra work. An adware extension reads the page, decides where to put ads, loads them from ad servers and reports your visit, and that happens on every tab. Ad-supported programs add their own background activity.

Removing the extension or program usually makes the browser fast again at once. If it stays slow, open the browser's own task manager with Shift+Esc in Chrome or Edge and look for extensions using a lot of memory or processor time.

My scan found nothing, but the ads continue. Why?

Because the source may not be a file a scanner looks for. Browser notifications are a permission stored in the browser, and many adware extensions are not flagged because they come from an official store.

Some ad-supported programs are only reported if you enable detection of potentially unwanted apps. So a clean scan does not mean the job is done. Check each browser's notification permissions and extension list by hand, and turn on Potentially unwanted app blocking in Windows Security before scanning again.

I let a "support technician" from an ad connect to my PC. What should I do?

Act quickly but calmly. Disconnect the PC from the internet first, so the connection ends. Uninstall the remote access tool they asked you to install and check Installed apps for anything else added during the call.

Run a Microsoft Defender full scan and offline scan. From another device, change your e-mail and banking passwords and sign out of all sessions.

If you paid by card, bank transfer or gift card, contact your bank or the card issuer immediately, and report the scam to the police. Do not answer if they call back.

Can an adware pop-up infect my PC just by appearing?

No. A pop-up, a notification or a new tab is only a web page or a message. It cannot run programs on Windows by itself, provided the browser and Windows are up to date. Infection needs a step from you:

  • running a downloaded file
  • installing an extension
  • giving a stranger remote access

That is why scam pages work so hard to make you click. Close such pages with the tab's X or by closing the browser, not with buttons inside the page, which may start a download.

Is TabMemoryOptimizer a virus?

Not in the strict sense: TabMemoryOptimizer is unwanted software, classed here as an adware extension, not a self-copying virus. Security programs often label such software as adware, a potentially unwanted program or a browser hijacker.

It still needs removal, because it changes browser settings, shows ads and can lead you to unsafe pages. The larger risk is clicking an ad that leads to a fake update or scam page.

Will Fortect remove TabMemoryOptimizer?

Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.

For TabMemoryOptimizer, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.

Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
