Unable to open any antivirus programs, includingHijackThis

Hello, I have a problem with my laptop. It was recently infected with the Security Tool virus, so a window will pop up onscreen every 2 minutes or so telling me I have been infected with malware, and to remove it using Security Tool. At the same time, I also got infected with the Antivirus 2010 virus, which does basically the same thing. I followed instructions online to remove these viruses, with little success. I was able to delete a few files, but was unable to find the registry entries mentioned in the specified locations. I am now unable to run HijackThis, or run the installer for the program because it says i do not have the appropriate administrator powers, even though this user account has administrative privileges. I am also unable to run Malwarebytes' Antimalware. I have also tried both HijackThis and Malwarebytes' Antimalware in safe mode, with no success as they did not run. Any help would be appreciated.

We understand that you are having difficulty running certain programs, including HijackThis. However, in order for us to help you it is necessary that you provide us with a HijackThis log, and it is possible you may be able to trick the malware into letting you do this. First, download HijackThis to a clean computer, then rename it from HijackThis.exe to any other name you want, using an .exe extension, for example... YourLastName.exe. Once you have done that, burn it to a CD (preferable to using a flash drive that may easily become infected) then transfer the renamed file to the infected computer and run a scan, then start a new topic and include your HijackThis log.

If that does not work, try the following:

Download/run Rkill:

Please download Rkill from one of the following links and save to your Desktop:

One, Two or Three

• Double click on Rkill.
• A command window will open then disappear upon completion, this is normal.
• Please leave Rkill on the Desktop until otherwise advised.

Note: If your security software warns about Rkill, please ignore and allow the download to continue.

Next, please follow the guideline at the link below to start a new topic and post your HijackThis log. If you are unable to create and post a HijackThis log, then your only option may be to reformat your computer and reinstall the operating system.
