I'm receiving a windows explorer error when I start windows

Every time I start windows I get a windows explorer error asking if I want to send the error to Microsoft. My wireless internet won't work on the computer, I can't even search for the signal. I have Malwarebyte's anti-Malware but it wont let me start it. Symantec anti-virus does not come up with any thing and it keeps disabling the auto protect. I am running windows xp. If anyone has any ideas it would be appreciated.

Thanks
Robert
