Is this the result of a virus?

Also, is there any way to make it so that when you open a new tab in Firefox, it opens your home page instead of the "New Tab" screen?

ADWcleaner shouldn't have been a shortcut, should have been the program itself. Just redownload it anyway as it updates at least once a week and you have download it as it doesn't update itself. No antivirus is fullproof, even paid antivirus. You have to be careful where you go online. Use Web of Trust addon to keep you from visiting bad websites.
