What to do if you think your mac has a virus

These applications are much safer to use than applications from unidentified developers. With some types of malware, such as adware, you will notice immediately that your computer is infected. However, other forms of malware are more stealthy and operate so they cannot be detected by the user or operating system. The goal of these types of malware is to stay hidden while it continually infects as many computers as possible by using your computer as an entryway.

I will briefly describe the most common types of malware that can infect your Mac. Since there are many forms of malicious software, I will stick with the forms that you may be most familiar with and the most popular forms of attacks reported on Mac computers.

That is exactly the case when it comes to viruses and worms infecting your computer. A virus will hide itself inside another application, program, or file in an attempt to enter your computer undetected by you or the operating system. Once the virus is in your computer, it will replicate itself until it destroys or corrupts the system.

A worm will also multiply itself when it enters the system and continue to do so until it has destroyed the computer or destroyed all the data on the drive. The worm does not enter the computer the same way that a virus would. Instead of hiding within another file or application, a worm is its own program and is much more dangerous in how it infects your computer. The worm can replicate and multiply itself without requiring the user to interact with the program.

The best prevention against viruses and worms is to be careful which files or programs you download onto your computer. Emails that contain spam are common to have these types of links or files that can enter your computer. Always verify where you are downloading from, and keep your security preferences set to downloads from the Mac App Store and identified developers. A trojan horse attack can holster other forms of malware within to get past your security and infect your computer.

More commonly referred to as a trojan, this type of malware is created to lure the user into downloading the file by appearing as useful or needed. Instead of getting what you expected, the trojan will release a form of malware that can spread or destroy the computer. Prevention tactics to deal with a trojan would be similar to viruses and worms. Most malware will piggyback on files or software to enter your computer undetected. This goes hand in hand with malware statistics.

The studies only show malware that has been found. There is still other malware that has not been detected yet.

A rootkit is designed to be able to access your computer without the operating system detecting it, and release another form of malware that it will hide. The goal of a rootkit is similar to a trojan attack in that it will infect your computer with a form of malware by hiding it.

The difference in a rootkit is that it will actively modify the operating system using functions that make the rootkit and malware it carries remain undetectable by most anti-malware software. A rootkit can also be hidden in the form of a trojan attack and this method is seen the most often since it is the most discreet to the user. A rootkit enters your computer like other malicious software do. Some of the most common ways are through suspicious emails that contain attachments, or websites that say you need a specific plugin to be downloaded in order to view the webpage.

These attacks are meant to scam you, so make sure that you do not open or download anything that you do not recognize. You can always do a google search to find more information on the safety of a specific file or application that is unknown to you and Apple.

A ransomware attack is only noticeable after the attack has finished. Once this malware enters your system, its goal is to remain undetected by the system or any anti-malware software. It will typically use either a rootkit or trojan attack to accomplish this. While hidden, the ransomware encrypts all of your files stored on your hard drive.

The malware then locks your computer and displays a terrifying ransom message to get you to pay money for your data back. Ransomware will hold your data ransom and say that you can get it back if you pay the money. But this is not always the case. Most of the time the hacker will not decrypt your data after you pay the ransom and there is nothing the user can do to get their data back. This is a very unfortunate attack and can only be avoided through strict computer security. As with most malware, you will want to take any precautionary method you can to keep your computer safe from an attack.

This includes having an anti-malware software that can detect and remove any infected files. Also, since anti-malware will not be able to recognize every type of malware, it is up to the user to be aware of files and software that are downloaded to the computer. Even attachments from emails can be dangerous to open. Since the primary goal of this malware is to lock your information, the best defense a user can have is a safe backup of all their data.

Keeping multiple backups of your most important files is the best way to prevent a data loss scenario. As I mentioned before, these are only a handful of the most common types of malware that can infect your computer.

Other applications can get corrupted or infected too, especially if they have particularly weak security systems.

Another example could be an email app you use or an open-source application that is behind on their patch upgrades. If you think one of your applications is infected, a typical knee-jerk reaction would be to delete the whole thing and redownload it. Often, this will do the trick, but there are simpler solutions available. Clearing the application's cache should always be your first step, and, if there are optional hidden files, consider removing them as well.
