Getting Rid Of A Virus Or Malware On A Mac
Many Mac users think they cant get viruses, spyware, worms, or other malware. This isnt true, even though there are fewer viruses and malware targeting Macs than there are for Windows PCs and laptops. We’ve got an in-depth guide to Mac security, but we’ll give you a quick rundown here.
Some well-known examples of malware for Mac computers include:
These names give the impression of being antivirus products, but they are all actually malicious and designed to fool Mac users into submitting their credit card or Apple ID account details. Do not download them.
The two main risks Mac users face are false alert messages and previously installed malware. If you see any kind of message while browsing the internet along the lines of a problem has been detected with your Mac, this is highly likely to be an attempt to get you to download malware. Instead, make the following tips part of your daily Mac habits.
As with a PC, it is a good idea to equip your Mac with strong protection. AVG AntiVirus for Mac is a free and comprehensive cybersecurity tool that detects and blocks malware, spyware, ransomware and other security risks in real time. And its updated automatically to safeguard your Mac against the latest online threats.
What Is The Difference Between Malware And A Virus
Malware, or malicious software, has become a catch-all term for several different types of infections. Some install themselves and create a simulated infection, corruption, or hardware failure, therefore tricking you into purchasing their product to resolve the issue. This type is known as hostage-ware, ransom-ware, orscare-ware. There are malware infections that redirect your browser to sites that the creator has chosen. Alternatively, they redirect to a website that they are compensated for, based on the number of hits the site receives. Sometimes these infections can hide your entire root drive and all your subdirectories. Sometimes they capture your personal information and communicate back to the creator of the infection.
A virus, which has become a subset of malware, is a program that replicates and attaches itself to services or specific applications. Many malware payloads contain a virus file, such as a Trojan or a Worm, to help root the infection. Viruses were once an exclusive type of infection, but now they have been combined into infection packages of malware. Many malware packages incorporate rootkits to embed themselves into the kernel level of the OS, making them stealthy and more difficult to remove.

Scenario #: My Homepage Has Changed And I Dont Remember Doing It Myself
If you spotted this unusual behavior or a new toolbar is showing out of nowhere, or youve been redirected to a different web address different from the one youve initially accessed, these could be signs of malware infection.
It usually happens when you visit a website and you accidentally click on a link or a pop-up window.
This triggers the unwanted software to download and install on your device. The effects are not only annoying but also malicious and can compromise your data.
What to do?
You can always manually change your homepage address from your browsers settings.
But the actual cause of this behavior can be, unfortunately, rooted much deeper, and be a sign of a more serious malware infection.
Monitor Your Computers Performance
- Check the activity of your hard drive: If you arent running any programs and your hard drive light is constantly turning on and off, or you can listen to the hard drive as still working, you may have a virus that is working in the background.
- Examine how long it takes your computer to boot up: If you start noticing that your computer takes significantly longer time than usual to start, a virus may be slowing down the startup process. If you cant login to Windows, even with the correct login information, a virus has most likely taken over the login process.
- Look at your modem lights: If you dont have any background programs running and your modem transfer lights are constantly blinking, you may have a virus that is transferring data over the network.

How To Remove A Bitcoin Miner Virus
Illegal cryptocurrency mining is cybercrime and could be fought with by familiar means like various antivirus programs or complex manual removal. However, Bitcoin Miner Virus is a fileless malware. This means it does not leave traces and is especially difficult to detect.
Manual removal of the Bitcoin Miner Virus requires in-depth technical knowledge and is a far more sophisticated process than simply deleting the infected files. The process involves engaging with sensitive registry entries where the incorrect approach could cause irreparable damage and the device can no longer function.
An efficient antimalware software would be a much better option. Keep in mind that not all traditional antivirus software options can identify and remove Bitcoin Miner Virus.
Keep in mind that not all antivirus software options are capable of identifying and removing the Bitcoin Miner virus. This malware is fileless and programs that seek for malware based on the definitions of a virus can not detect it. To eliminate crypto-mining malware, scan your computer with legitimate security software like Comodo Antivirus, SpyHunter, or Malwarebytes that removes all types of malware including the fileless one.
Recover Or Reinstall Any Damaged Files Or Software
Assuming the scan detected and removed the virus, you might need to reinstall any files or programs that were damaged.
This is where backups come in handy, and we strongly recommend you make them regularly, at least once a week. That makes it easy to restore deleted files on Windows and Mac devices. For optimal results, make sure to get an external hard drive.

How To Scan Your Computer For Viruses
By default, Windows 10 is always scanning your PC for malware with the integrated Windows Security application, also known as Windows Defender. You can, however, perform manual scans.
On Windows 10, open your Start menu, type Security, and click the Windows Security shortcut to open it. You can also head to Settings > Update & Security > Windows Security > Open Windows Security.
To perform an anti-malware scan, click Virus & threat protection.
Click Quick Scan to scan your system for malware. Windows Security will perform a scan and give you the results. If any malware is found, it will offer to remove it from your PC automatically.
If you want a second opinionalways a good idea if youre concerned you might have malware, and your primary antivirus doesnt find anythingyou can perform a scan with a different security application, too.
We like and recommend Malwarebytes, which pairs well with Windows Security to provide an extra layer of protection for your PC. The free version of Malwarebytes will let you perform manual scans to check for viruses and other malware on your PC. The paid version adds real-time protectionbut, if youre just looking to test a computer for malware, the free version will work perfectly.
Windows 7 doesnt include built-in antivirus software. For free antivirus, you can download Microsoft Security Essentials and run a scan with it. This provides similar protection to the Windows Defender security software built into Windows 10.
