StartFenster virus is the search platform that contains a few features and provides a few fields, categories of searches for the visitor. The main search box and all the additional functions may resemble a legitimate search engine, so people continue using the shady domain as their online searching tool. However, that is not a good idea because the more shady pages you click on and visit the more exposed to possibly malicious content you get. 

All those redirects, pop-ups, banners, and other content reroute the user to advertising pages and sites with questionable material, possibly involving malicious scripts and direct malware downloads. StartFenster virus developers are not responsible for the content you end up visiting because once a redirect is triggered the website that appears on your web browser is not associated with the PUP developers – Aller media. The company has not so great of a reputation because many users blame the marketing agency for distributing PUPs and obtaining control over browsers with those shady tools.

Unfortunately, there are tons of malicious pages you may end up visiting, and this is how your machine can get more affected by the serious infection. StartFenster hijack itself is not dangerous, but the more time you give this PUP on your machine the more malicious content you get exposed to and can infect your machine further without even noticing.
