SCAN THE COMPUTER FOR SPYWARE —If you are experiencing slow computer performance, you
frequently receive pop-up advertisements, or you are having problems connecting to the Internet, your
computer might be infected with spyware. Use an anti-virus program that includes anti-spyware
protection (your program may require an upgrade) to scan the computer and remove spyware. For more
information, go to support.dell.com and search for the keyword spyware.
RUN THE DELL DIAGNOSTICS FROM YOUR DRIVERS AND UTILITIES CD — If all tests run
