Is RevContent ads dangerous?
From our report of Jun 2020 · not reviewed since
Revcontent - adware which collects specific information about users' habits online to create personalized ads
RevContent is the redirecting PUP that focuses on showing you commercial content, so the traffic can be rerouted to shady services and sites whose publishers need revenue.
Adware injects such ads on sites that you normally visit and does so without any permission, so every click and page visit can be monetized. This pay-per-click method is widely used by many PUP developers and sponsors because tricking gullible online users is an easy method to collect views.
Anything that shows "Sponsored by RevContent" and appears on the screen creating frustration should be considered possibly harmful. Any online site can possibly be involved in malvertising campaigns, during which users' data etc collected, tracked, and later on, sold to shady actors.
In most cases, you might not expect any other symptoms, so it is extremely hard to find the PUP that causes all the issues. You need automatic system tools for that if you want to gather al suspicious files at once.
RevContent virus or a RevContent PUP has initiated lots of discussions across the globe, and, most likely, we could find at least one topic related to these advertisements in every computer-related forum. However, you must know that this is NOT a virus.
It is a legitimate content recommendation network which has been collaborating with well-known websites such as Forbes, CBS, or NBC News. Nevertheless, there might be cases, when various ads might start popping out frequently and intruding on computing activity.
Warning: The service is also known as one of the fastest-growing advertising networks, so you should never call it a virus.
This article is meant to explain how this ad network works and when these advertisements can become a matter of concern. You can easily encounter "Sponsored by RevContent" ads while browsing the world wide web. As we said before, they are placed there by this advertising network .
It is a platform thru which, according to its Privacy Policy, "web properties can display certain third party content such as articles, videos, blog posts, and advertisements on their sites." It is obvious that these RevContent ads can be disturbing because they can be provided by the majority of your favorite websites.
If you are one of the PC users who has already noticed ads by RevContent, you might start thinking that your computer needs to be scanned because these ads might be caused by an ad-supported program . However, in most cases, these ads originate from websites you visit, so the owner of these sites are the only ones to blame here.
You may get exposed to shady sites and end up with the significantly affected machines. Make sure to reverse any damage with or a similar tool after the RevContent virus removal. Windows registry is not the place that should be altered manually, especially when you are not a tech-savvy person.
Usually, RevContent platform doesn't serve such annoying advertisements (sites that choose to publish them might display a "Before you go, check out more" window, but nothing as aggressive as adware programs do). Therefore, if you started encountering them already, you might be dealing with an adware program that seeks to generate pay-per-click revenue.
If you notice that clicking on pop-up or banner ads takes you to strange-looking websites, stop doing so and scan the system with anti-spyware or anti-malware software. You might want to use anti-malware software to remove RevContent ads.
Another thing that concerns computer users is that ads from the described ad network usually look really attractive and enticing. It happens because the advertising platform tends to use tracking cookies to learn more about computer users.
These tracking cookies observe your activities and collect the required data, such as your IP address, click data, referral data, and more. Such information is used to understand your needs; consequently, you might start receiving targeted ads that match your interests. If you want to avoid such activity, perform the RevContent removal with a trustworthy anti-malware tool.

Avoid annoying advertisements
If you want to avoid intrusive ads, you should check your computer and remove each of the questionable browser add-ons, extensions, plugins, and toolbars.
Some parts of them may seem new to you. Wonder how did they enter your computer? LesVirus.fr claims that these add-ons were likely installed by you in a bundle with freeware and shareware as optional components.
You have probably downloaded some other free program that included some attachments . To avoid that, you should be attentive when you install free programs onto your system because they may suggest you installing several additional apps in a bundle with them.
Moreover, aim for Advanced or Custom installation settings. These settings allow to review and deny offers to install the 'recommended applications,' while Default and Standard installation settings hide these statements. You just need to find these statements and deselect them - it is as easy as that.

How to remove RevContent ads
How to remove the RevContent 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
RevContent often works through an extension, so go through the extension list of each browser:
chrome://extensionsedge://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 on Windows 11: More > Extensions > Manage extensions. Full procedure with screenshots: Remove a browser extension
Step 2: Uninstall programs you did not mean to install
Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10, and sort the list by install date. Look at what appeared around the day the problem started and uninstall every program you do not recognise or did not choose.
Free converters, PDF and video tools, "system optimizers" and unknown browsers are the usual carriers of RevContent. If a name is unclear, search for it before you remove it, so you do not uninstall a driver or a Windows component.
Full procedure with screenshots: Uninstall a program or app in Windows On uGetFix
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 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
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.
Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan

Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files.
More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.

RevContent ads elimination methods
Just like you should never call the RevContent virus, you should also know that you cannot perform RevContent removal on your computer.
The fact is, the real ads from this ad network are legitimate and there is nothing to worry about. If you are annoyed by them, consider visiting websites that do not choose to promote ads via widgets
However, if you started seeing suspicious web ads over, again and again, all that you may need to do is check your computer for adware-type software and remove it. If after doing so ads by this ad network reappear, you should check one more time.
Potentially unwanted programs can be very annoying, so the most reliable way to eliminate them is to delete them automatically. The anti0malware tools are designed to perform proper RevContent removal.
However, some users do not want to use anti-spyware programs - they want to remove RevContent manually. We have provided a list of recommended anti-spyware programs in case you wish to fix your computer automatically. For users who wish to remove PUP manually, we have provided a manual removal guide. It can be found below the article.
The adware program is not likely connected to RevContent ads, however, it might be using the ad network to collect user's clicks on the ads. To block annoying ads that show up in Chrome, follow these easy guidelines:
Questions about RevContent ads
lesvirus.fr opens when I click links. What causes it?
When every click leads to lesvirus.fr first, an extension or a script on the page is rewriting the links. If it happens only on one site, that site uses aggressive ads; close it and use another source. If it happens everywhere, open the browser in a private window, where extensions are normally off, and try again.
No redirect in the private window means one of your extensions is responsible: remove the ones you do not know. A redirect in the private window too means the cause is outside the extensions, such as a notification permission, a changed search setting or a program installed on the PC. The removal steps in this guide cover each of those.
Did lesvirus.fr install a virus on my PC?
Very unlikely, unless you downloaded and opened something from the pages it led to. Redirect domains such as lesvirus.fr sell your visit to advertisers; they do not need to install anything to make money.
What can be installed is the thing that causes the redirects in the first place, such as an extension or an ad-supported program that came with free software. That is why the checks in this guide look at extensions, notification permissions and Installed apps.
A full scan with Microsoft Defender afterwards gives you a clear answer about the rest of the PC. If the scan is clean and the redirects stop after removing the cause, you are done.
What is RevContent?
RevContent is an adware extension, a kind of adware. It earns money by showing redirects through ad pages, and each view, click or redirect pays whoever runs it. It is not something people usually choose; it arrives through a free download, a fake button or a misleading prompt.
RevContent does not encrypt files or take control of Windows, but its ads are sold to anyone, including scam operators, so they can lead to fake virus warnings and unwanted downloads. The steps in this guide remove it from Windows and from each browser.
Which browsers does RevContent affect?
In the cases we checked, RevContent showed up in Chrome, Edge and Firefox. That does not rule out others on your PC, since adware installers often target every browser they find, and permissions and extensions sync across computers signed in to the same browser account.
Open each browser you have, go to its extensions page and its notification settings, and remove anything you do not recognise. Profiles count separately: Chrome and Edge can each hold several, and each one needs checking on its own.
Are the pop-ups I see really from RevContent?
Compare them with the details in the table above. RevContent produces redirects through ad pages, and the clearest sign of it is redirects to lesvirus.fr. Other adware looks similar, so check the name of the sending site at the bottom of a notification, the address in the tab that opened, or the newest entries on the extensions page.
If those match, this guide fits. If you see a different name, the same kind of steps apply, but remove the item you actually find rather than guessing.
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.
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.
Did RevContent 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.
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.
Will Fortect remove RevContent?
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 RevContent, 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.
