Tezllc.us

The Tezllc.us website appears as a third-party independent technical support service provider that you can trust to help you with problems related to your AV, router and printer. However, that is just a cover for a fake computer support company named Tez LLC. that is associated with a browser hijacker. The cyber threat associated with Tezllc.us may show pop-up windows loaded with a fake BSOD message from the Tezllc.us domain. The pop-ups by Tezllc.us are titled 'Security Error Code 0x80073afc' and claim to be a security warning from Windows. The 0x80073afc error may be associated with problems with the Windows Firewall and may be displayed with a system dialog box–not a pop-up window in your browser. Less experienced users might trust the messages from Tezllc.us and call 800-378-7722 and lose money on repairs they do not need.

Security analysts note that the developers of browser hijackers may use legitimate error codes and native Windows visuals in the design of fake alerts to convince users to call uncertified technicians. Moreover, the Tezllc.us pop-ups may redirect users to untrusted pages and invite them to download rogue security tools like Ad-Ware Pro and WiniShield. The browser hijacker linked to Tezllc.us is not perceived as a severe threat to the user's data but might convince less tech-savvy users to call uncertified computer support agents who might install harmful software on their computers without notice. The messages by Tezllc.us are displayed with JavaScript and users that have Java enabled in their browser may have difficulties closing them. BSOD error messages from Windows prevent users from using the computer properly while fake BSOD messages that are generated by a browser hijacker prevent users from using their browser properly. You can protect your computer by installing a credible anti-malware shield that can recognize browser hijackers and stop their advance into your system.
