What Are the Symptoms of Having Mac Malware?

Usually the symptoms of infection with the so-called virus vary, based on the type of malware that has infected your device. Here is a list of the types of malware usually targeting macOS:

  • Rogue Antivirus programs.
  • Adware and hijackers.
  • Trojan horses and other spyware.
  • Ransomware and screen-lockers.
  • Cryptocurrency miner malware.

Based on these malware types, there are several very important symptoms that you must be aware of:

Symptom #1: Poor Performance

One of the main symptoms of having such malware is the performance issues the machine experiences. Usually, some devices tend to slow down when a lot of programs are opened all at once or if their memory is full. But if your machine is generally freed up of space and is still lagging this may be a sign of a type of malware that is utilizing the resources of your CPU, so identifying the source of the CPU usage is the key to removing the malware related to this.

Symptom #2: Toolbars or Add-ons on Your Browser that You Did Not Remember Adding

If you see a new browser extension or toolbar, be advised that it may have been added by a so-called PUP (potentially unwanted program) that may currently be residing on your computer. Here is how to remove browser extensions and toolbars manually for different web browsers. You can see the instructions underneath as they can help you remove all toolbars and browser add-ons.

Symptom #3: Ad-supported Search Results, Pop-ups and Redirects

This type of symptoms are usually characterized by having a very aggressive browser hijacker that takes over the spaces of your search engine by replacing them with sites that lead to some site you have not even seen before. These types of fake search engines are cleverly disguised to appear like the original search engines (Google, Bing, Yahoo search, Ask, etc.) and they often lead to harmful, scamming and even phishing websites.

Another symptom of having such a hijacker is the browser redirects on your Mac. These redirects often appear randomly while you are browsing. They often lead to harmful pages and may even lead to tech support scam sites, the aim to deceive you that your computer is infected:

Such sites often aim to get you to either download a suspicious program such as fake antivirus software or call a tech support number, which leads you directly to the scammers themselves.

To make sure to remove these scams, you should clear up your web browser out of absolutely any cache and also perform any removal of browser extensions as mentioned in the step above. Here is a list of several annoying redirect “viruses” and ad-supported programs that are currently plaguing Macs:

We have also prepared a separate article that is specifically designed for the removal of unwanted ads. If you wish to learn how to remove ads, just click on the link.

Symptom #4: A Hoax Antivirus for Mac

Sometimes, when users Google a random fix for the problems on their Macs, they often end up downloading programs that only pretend to fix device Issues. We have been gathering more information concerning such programs and so far the main ones that are downloaded by victims according to our research are the following:

These types of fake optimizing programs and fake antivirus programs usually aim to get victims to pay their licensed versions in order for them to fix any issues that they have detected. The bad news here is that not only they run aggressive start-up scans that always tend to detect issues, but most of the issues detected by these fake programs are often issues that do not even exist and are completely made up.

Symptom #5: Suspicious Processes Running as Administrator.

This symptom is likely the most dangerous one, because having it on your device means that it may be affected by absolutely anything, ranging from an adware program to a Trojan or a Spyware directly residing on your macOS. Usually, these processes tend to be ran with administrative privileges and they are very invasive.

List of Suspicious Processes:

  • Your files may be stolen from your macOS.
  • The malware may have access to your Apple ID and passwords.
  • Your social media and other accounts may be hijacked.
  • Some malware can activate your Microphone and camera to monitor your activity.
  • Your device may become crippled by a rootkit or other destructive malware that may attack your drive.

In some cases, some devices even become infected with screenlockers, asking the user to type in a password, like the Padlock malware we have seen loose earlier this year:

There are many different malware for macOS. Malware, such as Apple Scan Macbook Live, Weknow.ac, Adobe Flash Player date scam, TuneupMyMac, #friend E-Mail malware and Auto Mac Speedup Pro are from the less harmful type and they are considered potentially unwanted programs. Then again, there are more harmful threats for Mac out there, like OSX.Trojan.Gen, Kaseya Agent, KeRanger Mac Ransomware, Padlock Ransomware that can be very harmful to both your data and your Mac.

Distribution methods for such a threat can be the following:

  • Malicious e-mail attachments.
  • Malicious documents, containing Macros.
  • Malicious files, disguised as portable programs, installers, key generators or any other software uploaded on websites with low reputation.
  • Malicious web links that either lead to a direct JavaScript infection or a drive-by download infection.
  • Infection as a result of another infected device on the network (worms).

Be careful when downloading and install software especially freeware from informal sites. It is suggested to avoid installing third-party apps from undependable websites too. If you do, make sure to inspect all details available in the Custom/Advanced setup option. There you may discover a method to opt-out the installment of additional deals as well as at some point maintain your device clean from potentially undesired/harmful programs.

Most Common Virus Threats on Mac

The most common issue with such a threat is, when the reputation of one, or more, prominent search engines, is misused as a disguise for the procedures of numerous unpleasant potentially undesirable programs like internet browser hijackers and the following threats:

SafeFinder, Akamaihd.net Virus, .Goldraiven Redirect, Yahoo Search Virus, Bing Redirect Virus,
Search Pulse Virus, Feed Chunk Redirect, “Adobe Flash Player is Out of Date”, Your Computer Is Low On Memory

So when your recommended online search engine Google, for example, maintains rerouting your searches to Bing it is most likely that your computer is contaminated with a potentially unwanted program.

Yet another problem that may be noticed when your device is infected with some kind of malware, spyware or an undeisred program like browser hijacker is unsolicited data collection. By turning on different modern tracking technologies like cookies, web beacons, javascript, and even Trojans, the nasty application may obtain a lengthy listing of sensitive information including:

  • Web browser’s web page.
  • Search queries.
  • Browsing activity.
  • Running system type.
  • IP address.

  • The domain of current Access provider (ISP).

Data records are likely to be utilized for the launch of targeted ad campaigns based on your preferences. They could be released on dark internet markets.
