Even though many Mac users long believed their computers were at less of a risk of viruses than others, that doesn’t mean they can’t get them at all. In fact, people who have owned both Windows and Mac computers have found themselves the victim of vicious malware on both. The following viruses are more common than you might think on many device types, and there are some telltale signs that you need to take action sooner rather than later.

Trojan Horses

Without the best Windows or Mac security measures in place, you may find yourself the victim of Trojan horses. This virus type affects Macs and PCs and looks like legitimate software. It finds its way into your computer before unleashing a virus once installed. One of the worst Trojan horse viruses is the MacDownloader. This virus works quickly to try to steal data from Apple Keychain.

Adware

Adware looks like a virus that’s designed to annoy you, but it has become more than just annoying. Adware on Android, iOS, and other systems can also bring spyware with it, which can record typing with keyboard sniffers and keyloggers. These can steal your passwords and, subsequently, your personal data.

Ransomware

Ransomware used to affect Windows PCs more than Mac, but both have been victims of attacks in recent years. Ransomware is malware that can publish and steal a victim’s personal data or even block access to it unless a ransom is paid.

One of the most famous ransomware attacks in recent years involved KeRanger. This ransomware would hibernate before issuing a .txt file with decryption instructions in return for Bitcoin.

Macro Viruses

One virus type that is perhaps one of the most violating is the macro virus. It attacks your computer by running an executory code to perform a variety of functions. These might include file corruption, hard drive formatting, and even accessing your microphone and webcam. People typically trigger such a virus when they open a file infected with a macro virus.

When Is It Time to Act?

Not every virus type will present itself right away. In fact, some of the common virus ‘symptoms’ can also mimic general computer hardware issues. However, there are a few telling signs that upgrading your computer security and undertaking virus removal processes are necessary now.

Your Computer Is Slow

Whether you have a Mac, PC, or something else, a slow computer can be a common sign of a virus. While many other things can also be to blame, viruses running in the background can impact your computer’s ability to operate at its usual speed.

You See Many Pop-Up Ads

Pop-up ads are not uncommon on computers not affected by viruses. That is why many people install ad blockers – so they can see as few ads and pop-ups as possible. However, ads can also be a sign that you have adware.

If you notice more pop-ups than usual, run a virus scan to rule out or confirm the presence of a computer virus that requires your immediate attention.

Your Browser Isn’t Behaving

Regular crashes, problems with responsiveness, and a spontaneous homepage change can all be some of the most common signs that your computer is affected by a virus.

It doesn’t matter what operating system you run or device you use; you may be susceptible to some of the most common computer viruses. However, by investing in superior security systems and being aware of the signs, you may be able to take a proactive approach to your online safety.
