BleepingComputer.com: Please Help - Whats Wrong With My Comp?

Hi all, this is my 1st post and I'm hoping someone can help me, as I dont know what else to do. I bought my computer in August its on Vista 32 bit and everything was fine until yesterday. Now I keep getting all kind of errors. It started saying I couldn't access the internet as the Apphelp.dll was missing, now its saying failed to connect toa windows service. Also when I try to access other things it will not allow me, for example when I try to go into my firewall it says error loading firewall cpl, the specific module could not be found. Please help, I dont know what else to do, its seems like my computer just wont respond to anything I do.
Thanks in advance

Sounds like virii and spyware to me.

Boot into Safe Mode With Networking, try to connect to the Internet. If you are successful, update your antivirus and spyware programs and run full scans. Get rid of whatever they find and reboot.
