Avast is blocked by Group Policy...

[Bluehotdog5]

This is really starting to tick be off. The antivirus software I've been using for the last couple of months doesn't want to open. Whenever I try to open it, it say's
"This program is blocked by group policy. For more information, contact your system administrator"
I've disabled windows Defender, rebooted, and the problem persists. I can't contact windows Support either, since I'm using an OEM copy.

Any idea what this problem could be?

EDIT: Also, I'm using Home Premium, so the Group Policy Editor doesn't work for me

Then you have a major issue that cant be resolved without a format. Sorry to tell you but you got infected and they added your PC to a group policy. There is no way to undo that unless you know the Admin password that they had set to remove yourself.

Here's something that may help you out:

1. Click Start, Run and type regedit.exe and press Enter

2. Navigate to the following key:

HKEY_LOCAL_MACHINE \ Software \ Policies \ Microsoft \ Windows NT \ SystemRestore

In the right-pane:

* Delete the value DisableConfig
* Delete the value DisableSR

3. Exit the Registry Editor.

In Windows XP Professional, you can accomplish the above using Group Policy Editor as well.

1. Click Start, Run and type GPEDIT.MSC

2. Navigate to this path:

-> Computer Configuration
--> Administrative Templates
---> System
----> System Restore

3. Set Turn off System Restore to Not Configured

4. Set Turn off Configuration to Not Configured
More Information

Turn off System Restore corresponds to DisableSR registry value. With this Policy is turned ON, the System Restore tab may be missing in My Computer Properties. Also, when you run System Restore (rstrui.exe), you receive this message:

System Restore has been turned off by group policy. To turn on System Restore, contact your domain Administrator.

Turn off Configuration corresponds to DisableConfig registry value. With this Policy turned ON, the System Restore tab will remain displayed but the user cannot configure the SR options. It reads disabled by Group Policy.

Or perhaps you can review this Control of System Restore function has been disabled by "Group Policy".

How to regain control?

Go to Start>Run, key in gpedit.msc and hit ENTER. Under Computer Configuration, expand Administrative Templates, expand System, then click on the System Restore folder. In the right-hand pane, double-click on Turn off Configuration and, under the Setting tab, click in the radio button beside
Not Configured. Click on Apply then OK.
