Mac Shield

Mac Shield is a fake security program, which is a clone of Mac Guard. It targets Macbooks despite the common opinion that Macbooks are resistant to various types of malware. Generally, Mac Shield works as any rogue antispyware, by pretending to be a security program which detects numerous errors in the computer. However, protecting the computer is not the main purpose of Mac Shield. In fact, it does not have an ability to do that. Instead, it wants to make the users cough up their cash as soon as possible by offering a completely worthless product.

The main mean of Mac Shield’s distribution is through hijacked sites and faked search results. It is easy for the creators of this rogue to use the most popular search keywords, and make their site, which distributes Mac Shield, appear at the top of the result list. Then if the user clicks one of these links, a prompt appears saying “Windows Security has found critical process activity on your PC and will perform fast scan of system files”. The only way to get rid of the notification is to click “OK” button. However, the fact that the user is being prompted about Windows Security when he is running on Mac OS should be suspicious already.

Once the “OK” button is hit, a Windows OS interface window appears and a “fast scan” is performed. This is where the user should realize that the whole thing is a scam already. Needless to say, that after the “scan” the infection will start downloading a ZIP file for Mac Shield automatically, and after the installation the program launches automatically.

Mac Shield performs a fake system scan at once, at the same time sending various fake security notifications, which say things like:

Unregistered Copy
Sorry, the copy of your program is unregistered. Register to have an ability to cleanup your system.

Virus Found
Infected file detected:
Virus: Malware
File: SelfTest.dist

The system is infected
Your system is infected. It's highly recommended to cleanup your system to protect critical information like credit card numbers, etc.

Virus Found
Infected file detected:
Virus: Spyware
File: Terminal

Since Mac Shield is a malicious and fraudulent program the user must ignore all the messages and the scan results, because in the end, the only thing that this program wants is to rip the user off. It offers a lifetime protection for $79.95, but that would never work out. The only way out of this situation is deleting Mac Shield for good. No good can come out of allowing this program to stay in the computer, so one must remove Mac Shield as swiftly as possible.

Right click on it, and choose “Move to Trash option from the menu. If Mac OS asks you for our password, type it in. Afterwards MacSecurity should be deleted from the system.
7. Now click on Apple Menu and select System Preferences. When the menu opens, choose Accounts under the System category. Not click on the Login Items.
