If your computer is acting slow, why not do the Tango? Go to
www.securitytango.com and click the "Let's Dance!" button on the left. Print out the instructions and follow them
exactly! Don't skip any steps and make sure you do everything in safe mode. The process will take several hours or longer. It works on both PC and MAC platforms. Just make sure you select the correct platform for your computer.
If you are uncomfortable doing this on your own, contact someone in the computer club for help.
