unTabs Virus Extension -How Did I Get It

The primary method which unTabs uses to spread is to be silently installed on your computer along third-party program installers. Usually these may be freeware programs that you are looking to download on your computer. These programs could be your free media player, codec pack, file converter, torrent downloader or any other app you have googled for. There are some suspicious websites that spread modified installers of freeware programs and unTabs may be bundled within those installers “as a free useful extra”. You can usually encounter the unTabs application in one of the steps of the “Custom” or “Advanced” installation modes in the setup of the program you may have recently installed.

Other methods by which unTabs may have been situated on your computer is if you have visited a suspicious website and approved it as a browser extension on Google Chrome.

→ %System32%\GroupPolicyUsers
%System32%\GroupPolicy

In addition to creating files in the system directory of Windows, the suspicious application also creates multiple different Windows registries in the Windows Registry Editor. These value strings include attacking the following sub-keys:

• Google Chrome
• Run

After the unTabs virus has already modified your computer, the suspicious extension may collect the following information from it, in order to display it’s targeted advertisements:

• Your IP address and location.
• System language.
• Browsing history.
• Online clicks.

Although this information is not known to be shared with third-parties, the unTabs extension may display you advertisements based on what you have searched online to get you to click on them. And this cannot be good in any way, because some of those advertisements may lead to third-party websites that may be tech support scams, phishing sites or even malicious web sites that may infect your computer.

How to Protect Yourself in the Future

Cyber-crooks have become very smart in both developing viruses as well as methods of infection of users. Both home users and enterprises should beware and always apply the following advises to the PCs in their networks:

• Make sure to use additional firewall protection. Downloading a second firewall (like ZoneAlarm, for example) is an excellent solution for any potential intrusions.
• Make sure that your programs have less administrative power over what they read and write on your computer. Make them prompt you admin access before starting.
• Use stronger passwords. Stronger passwords (preferably ones that are not words) are harder to crack by several methods, including brute forcing since it includes pass lists with relevant words.
• Turn off AutoPlay. This protects your computer from malicious executable files on USB sticks or other external memory carriers that are immediately inserted into it.
• Disable File Sharing – it is recommended if you need file sharing between your computer to password protect it to restrict the threat only to yourself if infected.
• Switch off any remote services – this can be devastating for business networks since it can cause a lot of damage on a massive scale.
• If you see a service or a process that is external and not Windows critical and is being exploited by hackers (Like Flash Player) disable it until there is an update that fixes the exploit.
• Make sure always to update the critical security patches for your software and OS.
• Configure your mail server to block out and delete suspicious file attachment containing emails.
• If you have a compromised computer in your network, make sure to isolate immediately it by powering it off and disconnecting it by hand from the network.
• Make sure to educate all of the users on the network never to open suspicious file attachments, show them examples.
• Employ a virus-scanning extension in your browser that will scan all the downloaded files on your computer.
• Turn off any non-needed wireless services, like Infrared ports or Bluetooth – hackers love to use them to exploit devices. In case you use Bluetooth, make sure that you monitor all of the unauthorized devices that prompt you to pair with them and decline and investigate any suspicious ones.
• Employ a virus-scanning extension in your browser that will scan all the downloaded files on your computer.
• Employ a powerful anti-malware solution to protect yourself from any future threats automatically.
