Slowly dieing

I got a virus from I don't know where this morning and now my laptop is a wreck. It's not an online thing, since I can still post here but Internet Explorer is the only thing I can use now. I think it's a CPU thing, since it reports that I have a low drive memory or something and Windows Explorer is to full capacity. That thing is like a time bomb, overcharging by the second or something... and I think no one understood a thing that I said.



Argh, the point is, if someone even remotelly knows what I'm talking about or knows a good Anti-Virus or Online Virus Scan page, can you please help me??? Pleaseee... yeah, I got to the point of begging, sorry. :(
