Hello! I'm sorry that nobody posted a reply to your thread until just now.
If you are unable to download, run, or install any programs, I would suggest that you boot your computer into Safe Mode with Networking, which you can do by restarting your computer and pressing F8 while it's booting up. From there, you should use the arrow keys to select "Safe Mode with Networking" and then press the Enter key.
Once you've booted your computer into Safe Mode with Networking, I would suggest that you try running another antivirus scan, as well as an antispyware or antimalware scan, in order to try and remove this virus or other malicious file or program.
If you would like to try using a different antivirus program, I would recommend that you try using Microsoft Security Essentials, which is a free antivirus program that was created by Microsoft and can be downloaded from the link below.
If you need a free antimalware program, I'd suggest that you try using MalwareBytes, which can be downloaded from the link below.
Also, perhaps you should try using Mozilla FireFox, which is a free browser that is safer than Internet Explorer and can also be customized with a variety of free add-ons and themes. If you'd like to try using Mozilla FireFox, you can download it from the link below.
Just so you know, I would suggest that you have more than one antivirus program installed on your computer at the same time, as they may end up conflicting with each other, which may cause false positives, as well as other problems. However, it is alright to have both an antivirus program and an antispyware or antimalware program installed on your computer at the same time.
Please let us know what happens!
