RSS is a family of Web feed formats used to publish frequently updated content such as blog entries, news headlines, and podcasts.An RSS document (which is called a “feed” or “web feed” or “channel”) contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with web sites in an automated manner that can be piped into special programs or filtered displays.RSS content can be read using software called an “RSS reader”, “feed reader” or an “aggregator”, which can be web-based or desktop-based. The user subscribes to a feed by entering the feed’s link into the reader or by clicking an RSS icon in a browser that initiates the subscription process. The RSS reader checks the user’s subscribed feeds regularly for new content, downloading any updates that it finds and provides a user interface to monitor and read the feeds.RSS feeds can now be used to deliver viruses,Trojan horses, worms and other types of malware.
