Hi there,

I'm having a lot of trouble which I recently obtained on my computer. Whilst visiting a cinema's website in Google Chrome (www.hoyts.com.au) and doing nothing else on my computer, I received a popup from my taskbar saying:

"Windows Security Alert: Windows reports that computer is infected. Antivirus software helps to protect your computer against viruses and other security threats. Click here for the scan your computer. Your system might be at risk now."

Immediately after, an icon came in my taskbar of a red and yellow sheld with a green stripe running through it, and a fake antivirus program popped up, labelled "Antivirus Action". It started performing a "scan" of my computer. I immediately tried closing everything that came up, turned off my internet and went straight to AVG and Malwarebytes to see if there was anything I could do. Upon trying to open AVG, I received the following error message:

Title: Security Warning
Message: "Application cannot be executed. The file avgui.exe is infected. Do you want to activate your antivirus software now?"
Options: Yes or No

Clicking Yes attempts to open the following URL in Internet Explorer: http://antispyroad.net/shop?abc=cGdpZD03JnI90C4x
Clicking No closes the pop-up, but then continues another fake scan in the toolbar.

The exact same thing happened when trying to open Malwarebytes, as well as Google Chrome, Mozilla Firefox and Internet Explorer.

I am now on another computer and have tried running both DDS and GMER on the infected computer (by transferring by USB stick) but get the same error message I have been getting of "Application cannot be executed. The file conhost.exe is infected. Do you want to activate your antivirus software now?" so unfortunately I can not do any preliminary scans on the infected computer.

I'm not sure what other details to provide, other than I am running Windows 7 Home Premium.

Thank you so much in advance for any help you can offer!
