MAC virus and its damage

 As the top level products of computer industry, MAC computers definitely have higher security than other kinds of computers. For MAC users, they don't worry about being attacked by virus or malicious programs, causing serious damage. But this situation has only kept for a short time when MAC computers are firstly released. With the constantly developing of MAC computers, more and more hackers are coveting MAC operating systems. Therefore, MAC security has been challenged. The fact has proved that MAC computers are likely to be attacked as well. Let's get to know about MAC viruses in recent years.

l         In 2004, a piece of worm virus named "Renepo" aiming at MAC OS X spread very widely. This virus tried to invalidate system security settings of MAC, and then download a remote control tool in order to let hackers perform damage. It is very dangerous.
l         In 2006, Leap-A virus (also named Oompa-A virus) emerged. It spread through iChat program. Once a MAC computer is infected with this virus, it will automatically search the contact list and send messages to contacts with a broken jpeg file.
  
l         In 2007, a new form of Trojan, OSX.RSPlug.A, broke through a big security defect of MAC OS. When users click on the images of an illegal website to watch the videos, there will be a message telling users that QuickTime Player needs updating. At this time, Trojan will download and install itself automatically according to users' computer configurations. This Trojan will install it with root permission (the highest level permission) so that it is not limited by account passwords. It changes DNS server settings of Mac system with scutil order to attract users to phishing sites.
l         In 2010, OSX/Pinhead, also named "HellRTS", pretended as a component of iPhoto to spread. It tried to open the back door so that hackers could remotely control and inject malicious code.

These are only a few examples of MAC virus in recent years. You can figure that MAC is not as secure as you imagine. MAC computers are not that strong against viruses and will be attacked by viruses as well. Data loss is the most common result of virus attack, and data loss brings users economic losses. You will never want to bear the losses.
  
In fact, facing data loss caused by virus attack, we still have many good solutions to reduce the loss. As long as we own MAC data recovery software, we can realize MAC data recovery easily. But choices of professional MAC data recovery software are really few. Some kinds of MAC data recovery software are so expensive that not many users are willing to choose them. However, with the constant development of software industry, professional MAC data recovery such as MiniTool Mac Data Recovery that is specially designed for MAC data recovery has been released. It provides users with free MAC data recovery service.
  
At last, I want to remind MAC users that we should do perfect virus defense work as well. In addition, keeping a professional MAC data recovery software in MAC is still rather necessary.
