I post this here because it's not AH related, so here it goes.  This morning I went to use the computer and it's all jittery, the cursor stops moving sometimes and it just feels "laggy" or "jittery".  Also, there is a larger than normal number of programs listed in the Control+Alt+Delete menu, and many with abnormal names such as "F9hyh" and "Itzakpr".  When I went into to Add/Remove Software in the control panel there are new third-party programs that are for help in searching (definitely not needed).  The day before, something changed my homepage and I went to this sight where somehow I got a virus.  Norton quaranined this, but I wonder if it really did not?  I ran the virus check and there's no problems also.  Thanks for the help.
