Tec-smartphone.com has nothing to do with either tech or smartphones, despite what its name may suggest. Instead, the website is a vehicle for conducting a popular browser-based tactic. What it aims to do is display a misleading and deceptive fake alert or error messages that all try to convince the unsuspecting visitors to click the 'Allow' button. Doing so will grant the tactic website all of the browser permissions required for it to start executing its true function - the delivery of unsolicited advertisements to the affected device.
The tactic chosen by Tec-smartphone.com is to pretend to be conducting a bot captcha check. It would display to its visitors an image of a confused robot accompanied by a prominently displayed message that states:
'Click Allow if you are not a robot'
Following the instruction will result in the delivery of intrusive advertisements that could start to interfere with the normal browsing done on the affected device. Furthermore, the displayed advertisements could redirect users to shady or even compromised third-party websites. Various offers for dubious applications or suspicious software updates could be presented to the users. The offers applications could be adware, browser hijackers, or other types of Potentially Unwanted Programs (PUPs), but they also may have malware threats lurking inside them. That is why it is recommended to abstain from clicking on any of the displayed advertisements and take suitable actions to stop the Tec-smartphone.com website's activity.
