Security Warning (Fake) is a fake message from tech support scammers

Security Warning scam

“Security Warning” is a fraudulent alert that may appear on victim's computer screen. The message provided by the alert may state that victim's computer has been compromised by Zeus virus, hacked by criminals, or used for illegal activities. This scam is designed to scare the victim and encourage him/her to call technical support for help. Unfortunately, the number provided on the said alert belongs to tech support scammers[1].

The deceptive “Security Warning” error message is usually caused by a malware installed on victim's computer. It causes repetitious redirects to phishing websites which display the the bogus pop-up and usually play an audio message reading its contents loudly.

The fraudulent website might trigger never-ending pop-ups and prevent the victim from closing them. Obviously, urgent Security Warning removal is required to stop the process that initiates these unpleasant activities. The alert type might differ, but usually scammers use such lines to attract victim's attention:

Security Warning (Fake) malware is related to OS Firewall software (OSFirewall.exe), which is a rogue and deceptive program that belongs to ‘malware’ category. To be more precise, it acts as a scareware type software, because once it slithers into victim’s computer system, it immediately starts to send frightening pop-ups that look like real system alerts.

These warnings claim that a suspicious and possibly malicious virus was found on your PC and that OS Firewall could not remove it automatically, so to save your computer, you need to call a number provided. Sounds ridiculous, right?

However, many computer users get cold feet when they see statements that their credit card information, login information, Facebook chat history, bank login details and Skype chat information are at risk. 

Some facts about Security Warning scam:

  • The malicious process that sends you these warnings is named OSFirewall.exe. You should not believe what this delusive program says to you.
  • Do not fall for its intimidatory tactics and do not call the number provided (0-800-260-5674 or a different one). Otherwise, these frauds behind this fake tech support number might attempt to talk you into providing personal details, including banking information or just ask you some details about your computer that will help them to access it and take control over it.
  • Plus, this scam tech support number may be a premium rate one, which means it will rip off a large sum from you for a single call.

Please, do not fall for the artifice of frauds[2], and do not let them take advantage of you. The good news is that you can stop these fake alerts for good by removing OS Firewall malware. We recommend you to remove Security Warning virus with a professional malware removal tool, for example, Reimage.

Protect your computer from tech support scam malware

Malware like OS Firewall can be spread in several different ways. According to ZonderVirus.nl[3], in most of the cases, the virus can be installed via fake software updates provided on high-risk websites on the web. We are sure you saw some fake proposals to install Java updates already.

You can identify scam offers to install software updates easily – they usually appear in intrusive pop-up windows or show up as ads or banners on untrustworthy web pages. Bypass such offers. You should install software updates only from verified and secure websites or from official developer’s site only.

What is more, OS Firewall threat can come in so-called bundled software packs, which can be downloaded from insecure download sites. To avoid installing dangerous or infectious programs, you have to check whether the software that you have downloaded has some additional applications attached to it or not. For that, opt for Custom or Advanced installation option.

If this configuration provides an extra window including a list of ‘recommended programs,’ it means you have downloaded a software pack. Therefore, you need to deselect the agreements to install these ‘recommended’ apps.

    Ive been getting these pop-ups for a while… Updated SpyHunter and it discovered this threat. Guys, remove it immediately. I believe it has installed several other threats to my computer, because SpyHunter found about 15 more threats besides this one!
