ok recently i went away on a trip and i come back and my mom messes with my computer and my comp started to lag on games it diddnt used to (lag really bad) and not because my internet connection, and avg takes up a lot of cpu so i uninstall it and then i try to go to control panel and i cant, i try like 30 things and finally i redownload avg then install it, it grabs 60 so viruses but doesnt fix my problem. every time i log into my user it says this "Windows cannot find ‘C:\WINDOWS\shell.exe’. Make sure you typed the name correctly, and then try again. Yo search for a file, click the Start button, and then click Search." , it appears on the taskbar as a folder named C:\WINDOWS\shell.exe so i click ok and im at desktop. also when i click the picture of my user to get into settings or when i right click the desktop and click properties it says this "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator."

First update and scan your computer with your security products such as antivirus and antispyware applications in Safe Mode. If your computer comes up clean after running your resident security products, you may want to consider running a System File Checker (SFC). This can also be run in Safe Mode should you prefer.
To get into Safe Mode, reboot and then either hold down or tap the F8 key repeatedly while the computer is starting up. To run SFC, close all applications such as Office, Messenger, Email, etc, and go to:
- Start
- Run
- Type in sfc /scannow (include the space before the " / ")
What SFC does is that it attempts to fix or replace critical operating system files. Sometimes this can be done without the installation disk, however it may prompt you for the appropriate operating system installation disk. If that is the case, then you know that you definitely have major file corruption or something missing. Insert the disk if prompted. Also you should run SFC using the Administrator account.
If you have the Vista operating system, the steps are a bit different due to the UAC. See the link below.

Don’t surf, play games or do anything while SFC runs. After it is completed, reboot your computer.
One of the major culprits in missing or corrupt operating system files is running a registry cleaner or optimizer. They can flag important shared files for deletion or cleanup. Another cause is malware.
