Omg. Everyone get out of this topic. Your all giving her bad advice. Stop trying to help, and just let the professional take over.
I am almost positive you do not have the same virus. There is over a thousand fake anti-virus virus's out there. Each one works, and acts differently. I know how to remove them. I've removed them a million times.
Thanks for being helpful, but at this point what she needs is real solutions that will work, not hopeful guessing based upon past experience.
Since I will be going to work in 10 minutes and cannot help you with your various error messages. I'll just do it all now.
If you remove the proxy server, and still cannot get online in safe mode. Download the file from another computer and transfer it over.
If the program will not run (Your doing this in safe mode). And you dont get a message from combofix telling you why it will not run. Right click the file and rename it to 1337.exe and then try again. It should run now.
If Combofix says it cannot run on your system being its 64bit or an unsupported operating system. Download and run

If Combofix gives you a time error, run it in reduced functionality mode first, then run it again after it removes stuff.
Post back your results. I get off work in 10 hours, and I can help you then if you need more assistance.
(Also. Googling it is stupid. You will most likely download another rogue antivirus in trying to download a removal tool. Just follow my steps.)
