System Security Tool virus: everything you need to know about this computer threat

Adware creators today are getting even more twisted and gather ever-increasing amounts of revenue with the help of programs like System Security Tool virus. This particular adware is capable of generating legitimate-looking ads which claim that the computer’s system is in critical condition, and encourage users to contact the remote tech support in order to solve this problem. In reality, there is no actual threat on your computer. Furthermore, if you call the number provided in the fake security notification, you will not be connected to the technician but merely to a salesperson waiting to sell you unnecessary security contract or offer other services. The scare tactics that these security support scammers use often work and the victims purchase the supposed security support contracts. However, we have to warn you not to try contacting the given number, not to mention buying the suggested products, because you may simply be scammed. The first thing you should do, if you notice such ads occurring on your computer is to scan your system with a reliable antivirus tool, such as Reimage. It will detect and remove System Security Tool and any other suspicious components from your PC.

There are also other ways of distinguishing fake ads from the legitimate system notifications if you suspect you have been a victim of System Security Tool hijack. First, you can try closing your browser and see if the notifications still appear on your screen. Even better, you can disconnect your device from the network and monitor your computer’s activity. If the notifications stop appearing you can be sure that they were simply System Security Tool ads, and you should not worry about the safety of your computer too much. However, as mentioned before, you should make sure that the system is virus-free by scanning your computer with some reputable virus-fighting utility. Finally, you should specifically examine to the content of the notifications. It varies minimally throughout the different ads; therefore, it is easily recognizable. Take a look at the following example:

Firewall Detected Potential Threads on Your Computer
Warning. Windows Security Essentials wasn’t able to block the threats. Windows detected several threats that will compromise your privacy and harm your computer.
Error Code: 0x000007c, Windows couldn’t install the definition updates.

If you notice ads featuring similar content occurring on you computer you most likely have an adware residing your PC. It is essential to take care of the System Security Tool removal if you want to keep using your computer safely and uninterruptedly.

Example of System Security Tool virus

How can this adware infiltrate my PC?

Even though some features of this program slightly differ from other programs of this particular category, the ways through which it is distributed are virtually the same. System Security Tool adware is distributed through a deceptive marketing method, also referred to as “bundling”. “Bundling” occurs when two programs are added to the same software package, and the user downloads them both in one go. You can imagine how useful such feature can be to the creators of the potentially unwanted programs. Their malicious creations can enter the users’ computers unnoticed and silently carry out the questionable activities. But this stealthy hijack can as well be avoided if you spare some more time to the new software installation process. Firstly, choose your source of downloading programs wisely. Secondly, before heading straight to the installation process, let you antivirus scan the downloaded application to determine its reliability. Finally, always opt for the advanced installation settings to monitor and manage all the optional installs.
