What is Looker extension

Looker is an unwanted browser extension that alters browser settings to install its own homepage address. Software of such is notorious for promoting fake search engines – which oftentimes display results provided by legitimate engines like Google, Yahoo, or Bing. The Looker hijacker is no different, as it redirects all search queries to Microsoft Bing. Developers in charge of such modifications use such a scheme to generate illegal traffic and gain money on various ads. It is also worth noting that some browser hijacker extensions may be able to control permissions, which prevent users from disabling or removing the add-on. The list of permissions may stretch even further and allow suspicious extensions to monitor browsing data (e.g., passwords, IP-addresses, history, geolocations, etc.) and collect it for selling purposes. Based on the clarifications above, we, therefore, advise you to remove the Looker extension and its residual files from your system. Use our guide below to do it fast and without traces.

How Looker extension infected your computer

Users may often be pulled into installing unwanted extensions while clicking on ads, hidden buttons, or hyperlinks. As a result, people end up on suspiciously looking pages that claim such extensions/programs are useful and should be installed. Alternatively, a similar infection scenario can occur when downloading free software installers from third-party websites. The installers may contain barely visible information about additional offers inside “Advanced”, “Custom”, or similar sections. Extensions like Looker could be offered as a useful addition to the main program, which some users agree on. However, even if a user ignores such offers, he or she will still be infected due to installation selected by default. This is why it is important to be careful and double-check the software you install for unnecessary additions like possible sponsored products.
