I would like to share my experience with you and talk about viruses created for Mac devices and how to deal with them. You may say that there are no Mac viruses as Apple does not allow it. However, I may say that there are plenty of nasty malware types like adware that open new tabs in your browser, redirect you to irrelevant pages and show numerous popups.
Yes, these are not real viruses. Adware like Search Marquis cannot clone itself and infect other connected devices. It cannot encrypt your files or cause any other harm. Its activity is related only to web redirects and excessive advertising. At the same time, who knows which rogue websites adware may land you on next time. It may happen that you end up on a phishing website where cyber crooks harvest personal information that leads to identity theft.
I strongly recommend removing all adware that penetrated your device. But there is a problem here. If you want to get rid of Mac adware, you cannot quickly find a solution. If you go to google and search there how to get rid of Mac malware, you will see that all top results offer you to buy and install some shady software. In reality, these Mac antiviruses do nothing, as we know that the Apple ecosystem does not allow apps to access other apps' data. No antivirus can really scan and check your files.
How to remove Mac malware
If your system is infected with adware and you do not know how to get rid of it, you may try to call Apple and ask what to do. You can find their phone number here: support.apple.com/en-gb/HT201232#us-ca.
Another option is to try your luck on Apple communities. Thousands of tech enthusiasts help uses with their problems there. Here is a sample thread: discussions.apple.com/thread/8226644.
There are other options too. Apple operating systems are not very difficult to use, and any person can remove adware manually by going through step-by-step guides posted on numerous malware removal websites. Here is a guide by BitAdvisors.com on how to remove Search Marquis malware.
Most rogue software works by exploiting bugs and vulnerabilities in your computer's operating system. And macOS has its own bugs too. To fix these vulnerabilities, Apple periodically releases operating system updates. To date, macOS has not proved attractive enough for cybercriminals and evil developers to flood it with malware.
To stays away from any surprises, it is recommended to update your OS as well as all apps installed regularly.
You should never install apps from unofficial app stores not controlled by Apple.
One of the ways for adware to penetrate your Mac computer is through bundled installs. You download and install a very useful app that is often free, but in reality, you get several apps. People never read user agreements written in small print. There it can be noted that you agree to install additional tools and provide some rights to them. Whenever you install something, be careful and read user agreements, and do not miss additional unnecessary software.
Do not install any software without urgent necessity. Any additional software widens the attack surface.
To be able to do bad things, current Mac malware requires users to perform some actions – grant rights. So, be careful with allowing any app to access your data, change settings, etc.
One more wise move is to make backups. iCloud or ordinary flash drives will help you not lose your data in case of a system glitch or malware attack.
Final advice - do use VPNs. Your connection will be encrypted, and attackers will not be able to find where you are actually located or what data your traffic consists of.

The COVID-19 pandemic brings heightened awareness to the importance of a robust and stable communications network. Zyxel Communications is helping service providers across the globe ensure that their networks provide the necessary connectivity and cyber security for their communities to function during these difficult times. As more people are forced to work and study from home, the impact on the network is quite profound. OpenVault reports a 41% increase in bandwidth consumption during normal business hours. This health crisis points to the importance of good network connectivity wherever you live. COVID-19 brings the true nature of the digital divide into real context.

Cyberattackers continue to seize on the dire need for information surrounding the novel coronavirus. In one of the latest examples, adversaries have created a weaponized coronavirus map app that infects victims with a variant of the information-stealing AZORult malware.
The malicious online map, found at www.Corona-Virus-Map[.]com, appears very polished and convincing, showing an image of the world that depicts viral outbreaks with red dots of various sizes, depending on the number of infections. The map appears to offer a tally of confirmed cases, total deaths and total recoveries, by country, and cites Johns Hopkins University’s Center for Systems Science and Engineering as its supposed data source. Malwarebytes issued a warning about the map last week, and Reason Cybersecurity this week has followed up with its own blog post, reporting additional details on the scam, gathered by Reason Labs researcher Shai Alfasi.

Over the last year, the education delivery model has changed rapidly. Universities have learnt to operate entirely remotely and now that learning may resume in person, a hybrid education model will likely continue. The transition from physical to online models happened so quickly that it left many IT networks exposed to serious harm from outside forces. With a hybrid model, there is likely a widening attack surface area.
A recent spate of attacks suggests that cyber-criminals are taking notice of the seemingly infinite weaknesses in learning centers defenses. But why?
One of the primary reasons is that universities operate large corporate-sized networks, but without the budgets to match. Add to that, teachers and students aren’t given training to use and connect their technology in a safe way.
To avoid falling victim to devastating cyber-attacks which often have dire consequences, we share three lessons universities need to quickly take on board.
Your Research is Valuable to Cyber-Criminals
There is a hefty price tag on some of the research conducted by universities, which makes it particularly attractive to cyber-criminals. The University of Oxford’s Division of Structural Biology was targeted in February by hackers snooping around, potentially in search of information about the vaccine the university has worked on with AstraZeneca. It’s not just gangs of cyber-criminals targeting research facilities, last year Russian state backed hackers were accused by official sources in the US, UK and Canada of trying to steal COVID-19 vaccine and treatment research.
With world-leading research hidden in the networks of universities, its unsurprising that last year over half (54%) of universities surveyed said that they had reported a breach to the ICO (Information Commissioner’s Office). The research conducted by many UK universities makes them an attractive target for financially motivated cyber-criminals and state-sponsored hackers in search of valuable intellectual property.
To add insult to injury, ransomware attackers are doubling their opportunity for pay off by selling off the stolen information to the highest bidder, causing a serious headache for the victims while potentially increasing the value of their pay-out.
Personal Information of Students and Staff Can Easily Fall into the Wrong Hands
Based on tests of UK university defenses, hackers were able to obtain ‘high-value’ data within two hours in every case. In many cases, successful cyber-attacks are followed by not only a ransom note demanding payment for the recovery of frozen or stolen data, but also the added threat of sharing any sensitive stolen information with the public.
