Lab.kaizenet.com pop-up windows will repeatedly and randomly redirect your browser to the huge variety of other websites. Some of them may be quite acceptable, whereas the large portion of these domains will be extremely dangerous. Lab.kaizenet.com domain is therefore used as an intermediary between your browser and plenty of other third-party resources to which you may be forwarded. However, occurrence of these pop-ups and subsequent redirections doesn’t take place by itself, without any reason. Most likely your computer is infected with adware or PUP (potentially unwanted program) that currently spews out such pop-ups on a permanent basis.
