Avast "This program is blocked by group policy."

“This program is blocked by group
policy. For more information, contact your system administrator” comes
up. I was able to scan avast by creating a guest accout and opening by
the small icon on the bottom of the screen. I also was able to scan, I
found the following:

-C:Users.…\BetterInstaller.exe
(status)Win32-Ezula-AGE

-C:.…\websChamberSquishy.Class Java:Agent-CLW

When I tried to move them to chest in avast nothing happend, the result is an error.

I have ran Super Anti Sypware, Rogue KIller and ad-aware. I also can not uninstall avast because of this.

Please advise.

have you tested the file(s) at www.virustotal.com ?..if tested before do a new scan
post link to scan result here

follow guide and attach logs AdwCleaner / Malwarebytes / OTL / aswMBR http://forum.avast.com/index.php?topic=53253.0

I cannot find the files to test. I only saw them in the scan log. I have tried 8 online virus scans.
