Security Tool sounds like a software designed to protect your computer and guarantee your computer security.
But it is not true.
SecurityTool is a fake anti-virus software.
Once you are cheated by its name and install it in your computer, you would get lot of trouble and risks without knowing what is going on your computer.
Security Tool, contract to its name, is not safe.
Users always receive fake scanning report that identifies those safe files and programs as dangerous ones.
Moreover, Security Tool convinces users to purchase some software by providing you a list of viruses which have been found in your computer.
Your privacy seems to open to others in such situation.
All you should do is remove this fake antivirus program from your computer right now and keep it away from your computer for ever.
However, it is not that easy to remove.
Here are some useful instructions and hope they would be helpful for you.
You can remove Security Tool manually.
But it is not realistic, because manual removal will still leave part of the program data in your computer, that is to say, manual removing this fake anti-virus program is not thorough.
The remained data will do harm to your computer, such as slowing down your computer or even affecting other software.
The common way to uninstall a fake anti-virus program is with the help of an uninstaller.
The same is the case of Security Tool.
But there is still one more problem, that is many uninstall tools can not automatically remove registry entries completely.
In such circumstance, you can try a uninstaller providing force uninstall function.
Here I can tell you a trustful one, Best Uninstall Tool.
Using its force uninstall function you can uninstall the Tool thoroughly and also remove all the other unwanted software.
