Is UltraHero ads dangerous?
From our report of Jun 2022 · not reviewed since
UltraHero adware is a deceptive application that claims to block ads and protect privacy
UltraHero is a potentially unwanted browser extension that attempts to promote itself as a reliable tool for browsing the web.
According to the main page of the app, it can increase the speed of the browser, clean it, protect private information and help browse securely online. Unfortunately, this couldn't be further from the truth.
In reality, UltraHero is an adware application whose main goal is to ensure users are exposed to as many advertisements as possible. As a result, those who install it immediately notice pop-ups, deals, offers, banners, and other commercial content constantly appearing while browsing the web.
Adware might not only be annoying to deal with due to advertisements but also encourage users to visit potentially dangerous websites, where they could be tricked into subscribing to push notifications, losing money on useless services, installing malware, or providing their personal information to unknown parties.

Asks to provide personal information
In some cases, users may also install the application after believing its promises.
On its official website, it is claimed that the extension can do many things at once, although there's nothing really concrete mentioned:
There is no explanation of how the app is doing all these things. The truth is, UltraHero adware was never designed to improve the user browsing experience, as its main goal is to spam people with ad campaigns that are meant to generate a commission each time an advertisement is seen or clicked on.
Some of these apps can be of dubious nature, and users might be encouraged to install other potentially unwanted programs or subscribe to fake services.
Whenever the official website of the app is used to install the extension, users are shown a lot of fake information. For example, a statement claims that UltraHero is rated 4.6/5 based on 1000+ Trustedpilot reviews, all while the app is not even rated by this website at all. It is also littered with other fake statistics and fabricated user reviews.
Besides, when the link to install it is pressed, users are instead shown a prompt to enter their email address, which could cause some serious privacy issues in the future. Remember that you should never trust random websites and expose your personal information to them, as it could be used maliciously.

How UltraHero ads got into your browser
From our report of Jun 2022 · not reviewed since
Adware is notorious for its suspicious operation and distribution.
For example, many people discover a potentially unwanted application running on their systems unexpectedly, without seemingly installing it in the first place. However, it is not the case, as adware rarely spreads using automatic methods such as software vulnerabilities or spam emails. Instead, misleading phishing messages and software bundles are commonly used.
These infiltration methods are relatively common and result in thousands of users getting infected each day. To avoid this unfortunate scenario, you should always pay close attention to the installation process of freeware you download from third-party websites. For example, choosing Recommended/Quick settings or missing the pre-ticked checkboxes often results in infiltration of potentially unwanted or malicious software.
How to remove UltraHero ads
How to remove the UltraHero extension
Do the browser steps in every browser and profile on the PC, then check Windows for the program that installed the extension.
Step 1: Remove extensions you did not add
In Chrome open
chrome://extensions, in Edgeedge://extensions, and in Firefox the menu > Extensions and themes.Remove every extension you do not remember adding, especially search, new tab, coupon, PDF, weather or video downloader add-ons. Check every browser and every profile, because each keeps its own list.
If an extension has no Remove button or comes back, a browser policy holds it (see "Managed by your organization" in the procedure below). The pages are the same on Windows 11 and Windows 10.
Chrome on Windows 11: More > Extensions > Manage extensions. Full procedure with screenshots: Remove a browser extension
Step 2: Uninstall UltraHero
UltraHero is removed like any other program, from the list of installed apps. In Windows 11 that is Settings > Apps > Installed apps, in Windows 10 Settings > Apps > Apps & features, and in both you can also use Control Panel > Programs and Features.
Select UltraHero, click Uninstall and follow the uninstaller to the end. Then look at the entries just above and below it when the list is sorted by date: bundled programs install at the same minute.

Step 3: Reset the browser
A reset removes what the steps above could miss:
- changed start pages
- site permissions
- hidden settings
In Chrome open Settings > Reset settings > Restore settings to their original defaults; in Edge Settings > Reset settings; in Firefox Help > More troubleshooting information > Refresh Firefox.
Tip: Bookmarks and saved passwords stay, while extensions are turned off and the search engine and start page return to the defaults.
Reset every browser on the PC, including Edge, which Windows 11 and Windows 10 always have.
Chrome on Windows 11: Settings > Reset settings. Full procedure with screenshots: Reset a browser and fix a hijacked search engine
Step 4: Scan the PC, then run the offline scan
A scan finds the parts of UltraHero that the manual steps cannot see. In Windows Security > Virus & threat protection > Scan options, start a Full scan and quarantine what it reports.
Follow it with Microsoft Defender Antivirus (offline scan) > Scan now, which restarts the PC and checks the disk while Windows and the malware are not running.
It takes about 15 minutes and works the same in Windows 11 and Windows 10. If either scan finds something, run the full scan again after removal until it comes back clean.

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.

UltraHero virus removal
It is important to realize that apps that claim to have some features but do not have them, in the end, are not genuine.
In fact, there are plenty of potentially unwanted applications that claim to be useful ad-blockers but then end up being the culprits of the unwanted behavior in the first place. UltraHero is one of the best examples of this behavior, as it claims to protect and improve user security, all while doing the complete opposite.
Security software is capable of finding all the malicious components on the system and removing them automatically for you. In fact, it is likely to remove the unwanted app in question so you wouldn't even bother with the manual guidelines below.
1. Uninstall the extension
If you want to uninstall an application that spreads as an extension, you should access browser settings and proceed with the following steps:
2. Clean browser caches
While deleting the unwanted extension should get rid of all the unwanted advertisements, let's not forget about data trackers that might remain on the local system. When installed, adware usually places cookies and other tracking technologies in cached data folders. This ensures that the information tracking about users' visited websites, clicked links, typed search queries, and similar would be automatically delivered to the adware authors.
Thus, you should make sure you eliminate these leftover files - and it's particularly important to do after adware removal. Alternatively, follow these instructions:
- 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.
- Open Mozilla Firefox browser and click on the Menu (three horizontal lines at the top-right of the window).
- Select Add-ons.
- In here, select the unwanted plugin and click Remove.
- Open Edge and click select Settings > Extensions.
- Delete unwanted extensions by clicking Remove.
- Click Safari > Preferences...
- In the new window, pick Extensions.
- Select the unwanted extension and select Uninstall.
- Click on Menu and pick Settings.
- Under Privacy and security, select Clear browsing data.
- Select Browsing history, Cookies and other site data, as well as Cached images and files.
- Click Clear data.
- Click Menu and pick Options.
- Go to Privacy & Security section.
- Click on Clear Data...
- Select Cookies and Site Data, as well as Cached Web Content and press Clear.
- Click on Menu and go to Settings.
- Select Privacy and services.
- Under Clear browsing data, pick Choose what to clear.
- Under Time range, pick All time.
- Select Clear now.
- Click Safari > Clear History...
- From the drop-down menu under Clear, pick all history.
- Confirm with Clear History.
Questions about UltraHero ads
What is UltraHero and why is it on my PC?
UltraHero 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 UltraHero, 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.
UltraHero will not uninstall. What can I do?
First restart the PC and try again, because the program may have been running and locked its own files. If the uninstaller is missing or fails, start Windows in Safe Mode, where most third-party programs do not start, and remove UltraHero from Installed apps there.
If it still refuses, delete its startup entry and its scheduled task, restart, and try once more. A program that actively prevents removal is behaving like malware, so finish with a Microsoft Defender offline scan. Avoid third-party uninstallers offered on search ads; several of them are unwanted programs themselves.
An ad showed a phone number and I called it. What now?
The number belongs to scammers, not to Microsoft or an antivirus company. If you only talked, hang up and do not call back. If you let them connect to the PC, disconnect it from the internet, uninstall the remote access program they used, such as AnyDesk, TeamViewer, ScreenConnect or UltraViewer, and run a full and offline scan.
If you paid or gave bank details, call your bank at once on the number printed on your card. Change any passwords you typed while they were connected, and report the call.
Why didn't my antivirus catch UltraHero?
Many security products do not block adware or notification sites by default, because users often agreed to them, even through a misleading prompt. Notification spam installs nothing at all, so there is no file to detect.
In Windows 11 you can make Microsoft Defender block potentially unwanted apps: open Windows Security > App & browser control > Reputation-based protection settings and turn on Potentially unwanted app blocking. If notifications caused the pop-ups, no scanner will report them; the fix is in the browser's site settings.
Can adware slow down my PC?
Yes. Adware runs in the background, loads ad scripts, opens extra tabs and contacts its servers, all of which use processor time, memory and bandwidth. Ad-heavy extensions also slow down every page, because they inspect and change it before you see it.
The effect is strongest on older PCs and when several adware programs arrived together. After removal, restart the PC and check Task Manager for anything still using a lot of resources that you do not recognise. Speed usually returns to normal once the ads stop.
Does adware steal passwords?
Ordinary adware is built to show ads, not to steal logins, and most of it never touches saved passwords. The line is blurry, though. Extensions that can read every page could capture what you type, and adware ads sometimes lead to phishing pages that ask for passwords directly.
If you entered credentials on a page reached through an ad, change that password from a clean device and turn on two-step verification. Otherwise, removing adware extension and clearing cookies is usually enough.
I clicked on one of the ads. Am I infected?
Probably not. Clicking an ad usually only opens a page, and a page cannot install programs on an up-to-date Windows PC without your help.
You are at risk only if you then downloaded and ran a file, allowed notifications, entered card or login details, or called a phone number shown on the page. Delete any download and run a full and offline scan.
Change passwords you typed, from a clean device. Call your bank if you gave card details. If you called a number or allowed remote access, see the next question.
Is UltraHero a virus?
Not in the strict sense: UltraHero is unwanted software, classed here as an adware extension, not a self-copying virus. Our report lists this damage: Installation of potentially unwanted software, such as browser hijackers; redirects can also lead to other malicious websites, resulting in monetary loss or personal data disclosure to unknown parties.
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.
Will Fortect remove UltraHero?
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 UltraHero, 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.
