What is fassurun?

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 common symptoms include:
- Random web page text is turned into hyperlinks.
- Browser popups appear which recommend fake updates or other software.
- 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.
- Web pages become extremely slow to download due to the multiple ads.
