Computer trouble

I've been having computer issues as of late. A virus apparently attacked my computer so I ran Norton Antivirus...it looks like it cleaned it all up but now I cant log into my blogs to update them. AAARRRGGGGHHHHHHHHH!!!!!!! So I've hijacked my hubby's laptop to ask for computer help. It says I need to enable cookies and java script...I enabled my cookies but I can't even find java script on my puter now. Someone please help!
