Kozaka
What is Kozaka?
This is a variant of the Web Cake/Lucky Leap adware. It is a web browser extension that will modify the user's home and search providers as well as display contextual and popup advertising in the browser. This adware program injects advertisements with its affiliate ad providers in order to serve a number of ad types including banner, inline text links and popups. These ads are aimed to promote the installation of additional questionable content including web browser toolbars, optimization utilities and other products, all so the publisher can generate pay-per-click revenue.
Once infected by this program, common symptoms include:
- Random web page text is turned into hyperlinks.
- Ads with red click here button will pop up when those links are hovered on.
- Other unwanted adware programs might get installed without the user's knowledge.
- Browser popups appear which recommend fake updates or other software.
- Web pages become extremely slow to download due to the multiple ads.
