ScreenSaver.app - macOS-based adware that is programmed to promote a fake search provider searchbaron.com
ScreenSaver.app is categorized as adware that targets macOS computer systems and promotes searchbaron.com.
This fake search engine is known to provide search results from another legitimate provider - Bing by employing Amazon AWS Service. Furthermore, this is just a small part that ScreenSaver.app might be capable of. Adware programs are known for their advanced advertising skills that force various pop-up notifications straight on the user's computer screen and cause redirects during browsing sessions when web browsers such as Chrome, Firefox, and Safari get infected.
ScreenSaver.app virus can appear in the Applications folder of a Mac machine and even create its own folder named "ScreenSaver". Afterward, the adware hijacks browsers and installs major changes in the homepage and new tab search sections. Also, the program might add suspicious extensions, add-ons, and tracking objects.
Collecting non-personal information is another activity highly promoted by ScreenSaver.app and similar adware. The developers use browser cookies to track information related to users' online sessions and habits. The adware might be able to record data such as the IP number, saved bookmarks, websites entered, links/ads clicked, etc.
Afterward, ScreenSaver.app might use the information for delivering targeted advertisements. Do not be surprised is you get loaded with various offers to purchase rogue security software, just decline all of them. Besides, be careful not to get lured in various technical support scams or surveys/questionnaires.
Some parties provide surveys that require entering personally-identifiable information. Besides, do not provide sensitive data to bogus sources as you might experience identity theft in the upcoming future.
ScreenSaver.app removal is the best option here to prevent unwanted activities from continuing. Removing the PUP might be an easier task if you scan the entire system in search of suspicious content first.

Avoiding adware is necessary if wanting to ensure full system stability
Injection of PUPs might decrease your computer's safety level as together with an adware program alongside comes the risk of highly-developed infections such as trojan or ransomware-related ones.
However, in order to avoid third-party apps, you need to gain knowledge on how do they reach the targeted computer system. According to research, there might be several ways for a PUP to land on a machine/device:
Additionally, you should employ an AV tool for ultimate system protection. Choose reliable software to secure your computing and browsing work automatically. Antimalware products are able to block access to malicious websites, alert when something bad is happening, and prevent suspicious threats from reaching your machine.
- Software bundling. A lot of third-party developers employ this deceptive technique so that it could work for their own needs. Bundled freeware comes together with the adware and sneaks into the computer system when the user opts for the Basic/Recommended installation option. To secure your downloads, change the configuration to Custom/Advanced.
- Third-party ads/links. There are many unsecured sources all over the Internet that might promote suspicious applications by attractively advertising them. Avoid clicking on questionable content that is provided to you on the web.
- Fake updates. If you are a frequent visitor of third-party networks, you might be provided with fake adobe flash player upgrades. Do not get tricked by such content and if you ever get concerned about some type of software update, you can check it online.
- Software cracks. If you like downloading products and services from p2p networks and various torrenting websites, you are very likely to end with an additional PUP. Skip these types of pages and get your software only from reliable sources and trustworthy developers.

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.

Keep in mind that the adware might fill your browsers with unexpected material that also needs to be eliminated in order to get rid of the cyber threat properly.
ScreenSaver.app removal requires full attention of the user and at least a little bit of experience in the cybersecurity sphere. According to experts from LosVirus.es, it is necessary to clean every part of your machine and browser, otherwise, the ad-supported application might renew itself within the next start process.
If you think that you would not be able to uninstall ScreenSaver.app virus from your computer on your own, you should employ antivirus software and let the tool to complete the task for you. The result would be much more effective.
Questions about ScreenSaver.app ads
searchbaron.com opens when I click links. What causes it?
When every click leads to searchbaron.com 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.
Is it safe that my browser was redirected to searchbaron.com?
Landing on searchbaron.com does not infect the PC by itself. A browser does not run programs from a page without your action. The danger is in the pages that come next:
- some ask you to allow notifications
- some show fake virus warnings
- some offer downloads
- ask for card details
If you only saw those pages and closed them, nothing more is needed than removing whatever caused the redirect. If you allowed notifications, remove that permission.
If you downloaded a file, delete it unopened, or uninstall it if you ran it. If you typed a password or card number on one of the pages, change the password and call your bank.
Why does ScreenSaver.app show me ads?
Because that is its whole purpose. ScreenSaver.app is an adware extension, and its operators are paid for every ad it displays and every click it gets. In this case the ads take the form of redirects through ad pages.
They are chosen by ad networks that accept almost any advertiser, which is why so many look like warnings or prizes. The ads are not a sign that your PC is broken or infected with something worse; they are a sign that something on it, or in the browser, has permission to advertise. Removing that permission or program stops them.
Do I have to clean every browser?
Yes, if you use more than one. We saw ScreenSaver.app in Chrome, Edge and Firefox, and each browser keeps its own extensions, notification permissions and settings. Chrome and Edge share the same extension format, so one installer can add the same adware to both, while Firefox has its own add-ons.
Check every browser on the PC, including ones you rarely open. If you sync a browser with an account, clean it while signed in, so that the removal reaches your other computers rather than the adware returning from them.
How do I know the ads come from ScreenSaver.app?
Look for redirects to searchbaron.com. That is the trace ScreenSaver.app leaves, and it shows up as redirects through ad pages. Ads that appear on every site, including ones that never carried ads before, point to something on your PC or in the browser rather than to the sites themselves.
A quick test is a private window, where extensions are off by default: if the ads disappear there, an extension is responsible. If they appear even with the browser closed, the source is a notification permission or a program in Windows.
Why didn't my antivirus catch ScreenSaver.app?
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.
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.
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.
Will Fortect remove ScreenSaver.app?
Fortect for Mac scans for malware and unwanted programs, and its free scan shows what it finds on your Mac before you decide anything.
For ScreenSaver.app, follow the plan on this page as well: removing a launch item or an app is done in macOS itself, and a scanner cannot undo what was typed or entered on the infected Mac, such as saved passwords that were copied.
Change your passwords from another device first, and if the page tells you to erase the Mac, a scan is not a substitute. The free scan costs nothing and the full-featured product needs a license.
