System Security might trick users that their computers are infected with viruses

Examples of System Security

System Security is the name used for describing three different cyber threats: rogue anti-spyware software,[1] adware programs, and technical support scam. All of these malicious applications might be distributed with freeware or shareware and enter the system without asking user’s permission.

Nevertheless, these cyber parasites are different, all of them targets Windows OS. Any versions of the operating system are immune to them. However, it doesn’t matter which variant of the malware affected your PC or laptop; you should remove System Security immediately. The best way to eliminate cyber threats is to use malware removal tools, such as Reimage.

System Security virus pretends to be a legit anti-spyware

System Security is a shady anti-spyware program that acts like a scareware.[2] This rogue software is spreading in freeware packages and questionable file-sharing sites since 2008. Once it gets into the system, it starts running system scans and providing fake results.

The purpose of the System Security virus is to trick users into purchasing program’s license. The free version of the software works as a scanner that detects numerous cyber threats on the computer. However, the program might identify legit system process, such as C:\Windows\System32\svchost.exe dangerous.

Additionally, it might provide numerous security alerts that warn about detected viruses, such as Spyware.IEMonster or Lsas.Blaster.Keyloger. These notifications redirects to the website that offers to obtain program’s key to clean the computer. However, it’s not needed because detected infections are not real.

If suspicious security alerts started popping up on the screen out of nowhere, you should uninstall System Security. It’s a useless program that does not bring any benefits to the users and cannot protect or clean your PC.

Nasty adware program delivers fake system security alters

Another version of the virus works as an adware that displays fake security alerts in pop-ups. System Security tool also spreads in software packages and can get inside inattentive users’ computers unnoticed.

On the affected device, System Security redirect virus makes several changes to Windows OS and targeted web browsers in order to display misleading pop-ups. The message tells that computer has been infected. As a result user’s device and privacy are at risk. Victims are supposed to call fake technical support staff via 1-800-754-3403 and tell the error code 0x000007c.

Cybercriminals might trick users into purchasing useless security software, trick them into revealing personal and banking information or install remote access tools. Therefore, making this call might not only increase your phone’s bill but lead to malware attack, money loss or identity theft.

Do not get tricked by Microsoft-themed System Security scam

Similarly to the previously discussed version of the System Security malware, this one also operates as technical support scam. Redirect to “Microsoft System Security Alert” scam website might be triggered by an adware program or potentially dangerous sites, for instance, adult-themed or gaming.

The “Microsoft System Security Alert” virus delivers a pop-up that tells that one of the recent visits to a particular website may have ended up with malware installation:
Microsoft System Security Alert
Oops!! Something went wrong with your Windows
Dear Windows User,
The Website you have recently visited may have downloaded the Malware and Virus on your Windows system.
Microsoft Defender is Suspicious about your Windows System Security.
Your TCP Connection was blocked by Your Windows Security System. Your Windows and Chrome has been locked until we may hear from you to immediately fix this issue. Please contact Microsoft Windows Help Desk Customer Support: +1-866-317-8835 (TOLL-FREE)

Computer users are advised not to fall for such scams and bear in mind that Windows Defender does not deliver security alerts in the browser, and Microsoft does not have phone support line for Windows users. However, if you are repeatedly redirected to technical support scam website, you should scan the device with anti-malware to remove System Security notification created by cybercriminals.

Distribution methods of the malware

Even though System Security has several version, all of them spread using the same bundling method. This software marketing strategy is widely used by developers of potentially unwanted or dangerous programs. It allows taking advantage of inattentive computer users.

The malicious application might be included as an optional component in software packages and hidden under Quick or Standard installation settings. These setups do not openly disclose about third-party apps. However, if you rely on them, you give indirect permission to additional apps to get installed.

To avoid System Security hijack and other undesired apps, you should always opt for Advanced or Custom setup and follow the instructions carefully. If you see pre-selected programs, unmark them all. Security experts from Bedynet[3] point out that most of them will not do any good to you and your PC.

Uninstall System Security entirely

The best way to remove System Security is to obtain a reputable security program and run a full system scan. It will identify if you are dealing with rough anti-spyware, adware or other suspicious application and stop its activities.

Of course, you can try manual System Security removal too. However, you will have to investigate the system and uninstall malicious programs, files and other components yourself. Virus-related entries might be not only installed to the system, but web browser’s as well. For this reason, you should reset them too.

You can remove System Security automatically with a help of one of these programs: Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, Malwarebytes Anti Malware. We recommend these applications because they can easily delete potentially unwanted programs and viruses with all their files and registry entries that are related to them.
