“Security Update Error” is a fake message that might pop up on your browser that informs that Zeus virus[1] detected on the computer. We want to point out that Windows Defender or any other anti-virus programs do not provide security alters on the browser. Therefore, it’s a pure scam, and you should not call “technicians” to get help.

Users are usually redirected to the malicious website by an adware program. However, some shady sites may trigger such redirects as well. This site delivers a security update error pop up
which says: is requesting your user name and password. The site says: “Security Update Error 0xB6201879 Help Desk: 44-800-090-3820 (TOLL-FREE)”


A username and password are being requested by The site says:
“Security Update Error 0xB6201879 Help Desk: +1 (888) 944-5714 (TOLL-FREE)”

Supposedly, users have to call the provided number and get necessary user name and password, as well as eliminating the infamous banking Trojan. The website itself warns that users should not shut down or reset the computer. If they do so, they are said to lose access to the computer “to prevent further damage to our network.”

Moreover, “Security Update Error” scam warns that user’s privacy and the computer might be at risk too. Due to the spyware, riskware[2] and Zeus attack, users may have lost financial data, Facebook and email logins, credit card information, pictures and other documents stored on the computer.

However, we want to remind that this alert is fake. Authors of the “Security Update Error” tech support scam wants you to call them. Why? They might have numerous reasons, for instance:

  • trick you into purchasing suspicious security software;
  • get your personal information, such as full name, credit card information or home address;
  • convince you to agree to install remote access tools to “fix the problem quicker”;
  • install additional malware or spyware on your computer.

It goes without saying that you should not make the call. Just close the browser. However, if redirects to the scam website continue, you should take care of your computer’s security. These redirects might be triggered by an adware program. Thus, you may need to put extra effort to remove “Security Update Error” virus.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
