  1. What You Don’t Know Will Hurt You Spyware and Computers in Public Libraries Aaron Schmidt, Thomas Ford Memorial Library www.walkingpaper.org

  2. Outline of Talk • Assumptions • What’s the Problem? • Explanation of Spyware • Removal • Prevention • Further Study

  3. Assumptions • You have some PCs with an Internet connection • You have inexperienced patrons browsing the web • You want to serve them well • Comfort downloading and installing simple programs

  4. Keeping your Computer Clean?

  5. What’s the Problem? Popups Hijacked homepages Redirected searches Slow Operation Search bars

  6. More signs you have spyware Your phone bill includes expensive calls to 900 numbers that you never made—probably at an outrageous per-minute rate. You enter a search term in Internet Explorer's address bar and press Enter to start the search. Instead of your usual search site, an unfamiliar site handles the search.

  7. More bad signs A new item appears in your Favorites list without your putting it there. No matter how many times you delete it, the item always reappears later. Your system runs noticeably slower than it did before. If you're a Windows 2000/XP user, launching the Task Manager and clicking the Processes tab reveals that an unfamiliar process is using nearly 100 percent of available CPU cycles.

  8. Task Manager • Control-Alt-Delete

  9. Signs of spyware A search toolbar or other browser toolbar appears even though you didn't request or install it. Your attempts to remove it fail, or it comes back after removal. You get pop-up advertisements when your browser is not running or when your system is not even connected to the Internet, or you get pop-up ads that address you by name.

  10. Even more signs you have spyware When you start your browser, the home page has changed to something undesirable. You change it back manually, but before long you find that it has changed back again. Everything appears to be normal. The most devious spyware doesn't leave traces you'd notice, so scan your system anyway. http://www.pcmag.com/article2/0,1759,1522648,00.asp
