Admin rights

I have an users who had a virus called cheap-o.ex. I removed the virus and removed it from the registry. Now my user who had admin rights can no longer remove or update software. If i log into the computer using my domain account that has admin right, i get the same error message saying i need admin rights to remove or update a software.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try running Windows 7 Repair Install. You need a working recovery partition or the Windows 7 DVD. Here is a Seven Forums tutorial to assist you.

In all likelihood the damage appears to be sufficiently bad that you should back up everything and reinstall Windows 7.

Have you tried to delete the windows profile for this user and have them log back in and create a new profile? Sometimes the profiles can become corrupt. If it was a virus it is possible that there are still remnants left on this machine.

Viruses also can corrupt or destroy core windows files. I would also try running sfc /scannow to try and repair the System Files.

Open the Control Panel, User Accounts, Change user access control and change it to the lowest setting and reboot.

The lowest UAC setting turns UAC OFF and should never be used.
The first thing to check is of course: are your accounts still inside the admin group!
...maybe that malware has removed them from that group.

You may need to temporarily enable the hidden "Default Administrator" account, as described here .....

Be sure to disable it again when you have fixed any rights/permissions issues.
Treat it only as an emergency account.
