Malwarebytes El Capitan

Posted onby admin

Malwarebytes Premium is an antivirus replacement, protecting you and your devices from malware, ransomware, viruses, adware, spyware, malicious websites, and more. It can identify threats no one has ever seen before, so you are protected from tomorrows online threats today.

There are no AV programs available that will run without impacting Mac OS negatively. As there are no viruses out in the wild for Mac at this time, there is no reason to risk ruining your OS experience. What is far more advisable is to watch what you are doing: do not download from 'free' download sites; only download from the app store or a trusted developer's site; there is no software to prevent the adware/malware popping up on your screen because these are scammers and keep changing their methods and it is very easy to get rid of it with Malwarebytes (developed by a long time contributor here) - their methods include hacking legitimate sites and re-directing you to one of their sites. So, be careful where you go and what you download; anything that costs money elsewhere and is being offered free will most likely include an unwanted addition. Also stay away from 'cleaning' apps as they 'clean' so well that they mess with necessary system files.

How to remove 'Your OSX 10.11 El Capitan Is Infected With 3 Viruses!' from Mac?

What is 'Your OSX 10.11 El Capitan Is Infected With 3 Viruses!'?

Malwarebytes

'Your OSX 10.11 El Capitan Is Infected With 3 Viruses!' is one of many scams designed to trick Mac users into believing that their computers are infected with several (in this case three) viruses. This one is categorized as a fake virus alert. Virus alerts and other fake messages of this type are usually displayed on deceptive, untrustworthy websites. Users do not generally visit these websites intentionally - potentially unwanted applications (PUAs) often force redirects to them. Similarly, PUAs are often installed unintentionally without users' knowledge. In addition to unwanted redirects, these apps serve users with intrusive ads and collect various browsing-related information.

This website enables a pop-up window stating that a trojan virus ('e.tre456_worm_osx') was detected and immediate removal is required. The deceptive website itself contains information that the the visitor's Mac computer is infected with three viruses: two malware and one phishing/spyware infection. To prevent further damage (loss of photos, apps, and other data), users are urged to scan their systems by clicking the 'Start Scan' button within five minutes of visiting this deceptive site (it contains a running timer). Once clicked, this button leads to download of the Mac-Mechanic app (the promoted app might be different). This website may seem to be an official Apple site, however, Apple has nothing to do with this scam. These deceptive websites generally promote apps and attempt to trick people into downloading them. To then use the apps, a purchase if often required. In summary, scams such as 'Your OSX 10.11 El Capitan Is Infected With 3 Viruses!' are used to extort money from users by tricking them into believing that their computers are infected with viruses. Do not trust these websites, or the applications they promote. The best option is to simply ignore these sites and close them. If a website cannot be closed in the normal way, use Activity Monitor and 'force quit' the browser app. Alternatively, restart the computer. Do not, however, restore the previously closed session, since this will reopen the deceptive website that caused the problem in the first place.

As mentioned above, most visitors arrive at these websites inadvertently - they are redirected by potentially unwanted apps. In addition to unwanted redirects, these apps often deliver intrusive ads (coupons, banners, surveys, pop-ups, and so on) that are displayed using tools that enable placement of third party graphical content on any site. Therefore, they conceal underlying content of any visited website. When clicked, they usually redirect to untrustworthy websites. Clicking these ads can allow download/installation of other unwanted applications. Many PUAs also collect browsing-related data such as IP addresses, search queries, URLs of visited websites, geo-locations, etc. This might also include personal details. Developers continuously share the data with third parties (potentially, cyber criminals) who misuse it to generate revenue. Thus, having potentially unwanted apps of this type installed can result in privacy/browsing safety issues or even identity theft.

'Your OSX 10.11 El Capitan Is Infected With 3 Viruses!' is just one of many scams of this type, and very similar to Your System Is Infected With 3 Viruses, This Mac Is Not Secure, Your MacOS 10.12 Sierra Is Infected With 3 Viruses, and a number of others. These scams are displayed on websites designed to trick people into purchasing unnecessary applications or pay for services. Unwanted apps that cause redirects to deceptive websites are usually very similar. Most are installed unintentionally, cause unwanted redirects, collect data, and deliver advertisements.

How did potentially unwanted applications install on my computer?

Some potentially unwanted apps have official websites from which they can be downloaded, however, most users install them through intrusive advertisements or when they are bundled with other (usually free) software. 'Bundling' is a deceptive marketing method used to trick people into downloading and installing unwanted apps by hiding them in 'Custom', 'Advanced' and other options/settings of the download/installation set-ups. Developers avoid disclosing information about the inclusion of unwanted apps in set-ups. Many users skip download/installation steps without checking the aforementioned settings, and developers use this to their advantage.

How to avoid installation of potentially unwanted applications?

Download software using official/trustworthy sources and avoid using third party software downloaders, installers, and other similar channels. Never skip software installation steps without studying them first. Check all available 'Custom/Advanced' (and other similar) settings/options and deselect offers to install unwanted applications. Note that intrusive ads may seem legitimate, however, many redirect to untrustworthy websites (such as gambling, pornography, adult dating, etc.). If you experience these ads or redirects, check the list of installed programs on your operating system and extensions, add-ons, plug-ins on your browser. Remove any unwanted/suspicious entries immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
