This site will look much better in a browser that supports web standards, but it is accessible to any browser or Internet device.
This page was getting *too big* so I've split the information to make it easier to find.
The most useful links are the Prevent browser hijackings, General troubleshooting advice and the Spyware, malware and problem software links to the left of screen.
Whatever you want to call it (Adware... malware... spyware... foistware ...) such software has the potential to generate very large incomes, not only for the creators of this plague, but also for the authors of freeware/shareware who become distributors. I don't expect the problem to go away any time soon - too much money is involved. Knowledge is our best defence.
Good luck.
