Has there been some time recently you were enjoying the Internet only to be asked if you would like to place a bet on next year’s World Series? Or maybe to buy a timeshare condominium in south Florida, or even a $2000 chair massager? Have you ever had half a dozen popups block your use of a web page, and not be able to turn them off? If any situation like this has ever happened to you, then you know full well what it is like to have adware infect your computer. Adware blocks your enjoyment of the net and slows down PC performance to a crawl. Worse, it can even be an early warning of still worse things to come. Wherever there is adware, spyware and viruses are likely soon to follow. Some spyware might only report back to some software vendor how you are using their program. But other spyware might also email your credit card numbers to a criminal’s office half way around the world. Viruses and worms can destroy your computer altogether. Even if you avoid the very worst damage these most common types of malware can do to your home computer, the odds are high your hard drive will slow down to a crawl for even the simplest of applications.
