What is SerialTrunc?

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.

- Random web page text is turned into hyperlinks.
- Ads with red click here button will pop up when those links are hovered on.

- Browser popups appear which recommend fake updates or other software.

Once installed the software will add a number of unwanted features to the web browser including inline text and multi-site searching, comparison shopping, related search results, additional offers and coupons as well as website ratings and reviews. It does this by analyzing the content of the web pages the user is visiting as well as tracking the URLs and navigation.
