Mac Security

Despite the famous claim that Mac OS are resistant to malware, here comes Mac Security – a fake antispyware program which appeared in early May. This software is distributed using the tactics called “blackhat SEO”. It means that the creators of Mac Security use the most popular search trends in their hacked sites, to make them appear at the top of result list. Therefore, if a user searches for something as simple as “Father’s Day” on Google Images, there might be images appearing in the results, which links the user to a hacked site, no matter whether his operating system is Mac OS X or Windows.

Just like that, the next second the user faces a fake online malware scanner which indicates there are errors in the computer and performs system “scan”. After the scan Mac Security is downloaded automatically whether the user likes it or not. Upon the installation this program performs changes in the operating system so that Mac Security would load every single time the user boots the Mac.

When Mac Security turns on, it fakes a system scan again and insists that there are many malware infected files which need to be fixed. But the rogue does not allow removing the threats, because it wants the user to pay for the license. The Control Center window also indicates the security status as “At Risk”, saying “Unfortunately, your computer is infected”.

Mac Security is a program which is very hard to close unless the user uses Activity Monitor to terminate the process. Otherwise it might be impossible to remove this malware from the computer.

There is a list of fake security notifications which should be ignored as well as the scan results. These messages are as follows:

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

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.

Even if the user ignores these messages and the scan results, Mac Security has a way to force him into paying for the program. This program is able to launch the web browser automatically and load various pornographic sites. This way Mac Security terrorizes the user trying to make him think that there is no other way out of this situation, except for paying full price for the program. However, nothing good can come out of purchasing this application and the user must remove Mac Security together with all of its related files.
