Mt wife's employer, Grassroots Spa, called me today with this problem. Whenever the computer boots or attempts to run a program, an error pops up saying "Error" in the top bar, then displaying the file path of the program which has been blocked. This applies to any and all programs run. With most, when "Ok" is clicked, it pops up two more times. Some programs will then run, most will not. McAfee is disabled and cannot be re-enabled, Add/Remove programs will not open, and any .msi files are blocked by an administrator setting, "The system Administrator has set policies to prevent this installation" Opening gpedit.msc and looking at the group policy, Local Computer Policy->Computer Configuration->Admistrative Template->Windows Components->Windows Installer->Disable Windows Installer is set to Not Configured. I attempted to re-install McAfee, and it will not re-install due to Java being out of date, and Java updates are also not able to run. Malwarebytes cannot install, HijackThis and DDS are also blocked. The attached .jpg is the error shown when running DDS. As with any other program, the error pops up 2-3 times, certain programs run afterwards. Most do not. I was able to update Firefox, but not install Chrome. I have attempted to install and run Avast!, and Spybot with no success on either. RootRepeal was able to generate a log, included at the end. I noticed it found a rootkit, which finally gave me a title for the post. Not being able to do any scans left me with no idea what was going on. I have tried everything I can think of, and now must ask for assistance. If I have left anything out, please let me know and I will attempt to get you the information as quickly as possible.

Neither Ad-Aware nor SUPERAntispyware will install, same error.
