Can't open any programs, says restricted by system administrator

This morning, I was able to log in fine, but when I tried to run Firefox, I got a message that said the System Admin restricted access. This happened to most programs (I haven't tried them all). The start menu became completely reconfigured, now showing in an older style and displaying no shutdown buttons. I am able to access all files and was able to copy and paste my personal ones to a flash drive in case I need to reformat. I have Vista Personal Edition (i think). Does this look like anything you've seen before?

PS.

Running Norton Anti Virus (came with computer)
Logs said that it blocked a few Trojans last night and they picked three up on scans I started this morning.
Also blocked incoming traffic to unused ports (complete logs to come)

EDIT:

Firewall blocked connections at 69.121.43.27 @ port 26418
Programs accessing internet during remote connection attempts:

C:\Windows\HelpPane.exe
C:\Windows\System32\wermgr.exe

Trojan info:

Auto Protect

C:\Users\Jake\Appdata\local\temp\arcf8b4\ca.exe

Could not pull info on Trojans detected by the scan

ask the adminastrator if they messed with your acount

I am the admin, but thanks for replying. Turns out that my hard drive went faulty along this path, and HP is shipping me a new one. This should take care of the problem. Luckily it was under warranty, or I would have to pay for a $50 charge for calling them, 500GB hard drive, and Vista Home.

Correct me if I'm completely misinformed, if the hard drive goes, then the problem goes? It can't reside anywhere else (Besides removable media?)
