What Could Be the Symptoms of Having a Mac Virus?
Usually the symptoms of infection with the so-called Mac virus vary, based on the type of malware that has infected your Mac. Here is a list of the types of malware usually targeting Macs:
- Rogue Antivirus programs.
- Mac adware and hijacker viruses.
- Trojan horses and other spyware.
- Ransomware and screen-lockers for Mac.
- Cryptocurrency miner viruses.
Based on these Mac 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 a Mac virus is the performance issues the machine experiences. Usually, some Macs tend to slow down when a lot of programs are opened all at once or if their memory is full. But if your Mac 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 Mac. 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 Mac 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:

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 Mac means that it may be affected by absolutely anything, ranging from an adware program to a Trojan or a Spyware directly residing on your Mac.

Viruses, such as Apple Scan Macbook Live, Weknow.ac, Adobe Flash Player date scam, TuneupMyMac, #friend E-Mail virus and Auto Mac Speedup Pro are from the less harmful type and they are considered potentially unwanted programs. Then again, there are more harmful viruses 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.
