When I came to log on to this site web security guard warned me that doubleclick.net website had been reported as a phishing site. Web guard allowed me to block it and I have been able to access my account with no problem. Has this site somehow got linked to plusnet ? Please advise.
doubleclick.net is an advertising host. You see their ad's on thousands of sites across the net. They track clicks on their banners before directing you to the site that they are advertising, using the track logs as a method for charging the advertisers. Examples can be seen at this online tech newspaper, for example in the story about Fasthosts (hover your mouse over the banner ads above and to the right, and you'll see that they are doubleclick ads - check the status bar on your browser) Not neccesarily bad, and it does make it easier for those who don't want the ads to block them - one simply has to block the urls via a host file, or firewall rule. (or browser plugin) Nothing to do with PN at all.
