Sorry your having trouble, let's see what we can do to get you back up and running.
What product are you running?
Might you have any scan logs, that would show was has been detected, and what action taken on them?
There are several tools we could use, just need to better understand the state of your system, so we can pick one.
What symptoms do you currently see?
Dell 10.1" Netbook purchased May 2009.
Didn't print off scan log and can't obviously access anything
I power on, can't get safemode to work
Logon screen comes up
I tried logging on via each user listed (total 5 of us)
Acts like it's going to go on and set user settings, but no task bar or icons appear
