Vista - Missing A Bunch of System32 Files (Virus Attack)

I am a student in college and I left my vista disk in my storage. So I'm on summer break without it (big mistake). and so i was attacked by a virus and now i cannot update and all these pop-ups keep coming. i finally defeated the viruses but it took stuff with it. "system restore" didnt help because something is missing, cant update something is missing, etc.

please help how can i reload my system without a disk... is that even possible? please please help me!!!!

My System:
Vista Home Premium 32bit
AVG Anti-Virus Free

Try running System Files - SFC Command, and maybe try running a full scan with one or some of these to see if there still maybe some infection left.

but what about the corrupted/missing System32 files? are they ok and the viruses are just blocking it? when i try to hibernate or go into sleep mode it just takes me to the log in area and does nothing... im just confused about the system32 files... are they deleted or are they just being blocked off.

If you're missing system files, running sfc/scannow from an elevated command prompt, as in that tutorial, should replace and/or fix any missing/corrupted system files. Did you run it as per the tutorials instructions?
