Computer infected. Cannot do anything including get into email or on internet

Hi. Whenever I try to get on the internet or check my email I get an error message that says "Application cannot be executed. The file wuauclt.exe is infected. Do you want to activate your antivirus software now? When I close the error message it just pops back up and will not allow me to do anything. When I click yes to activate the antivirus software it wants me to buy the program. Another thing that happens is that a porn website keeps popping up. My 10 year old son uses my computer as well and is pretty trustworthy and has assured me that he has not been messing around with anything like that. I do believe him because he basically just plays games on the computer. He did admit to going ahead and trying to download games that were deemed as being potentially unsafe for the computer. I am sending this email from another computer because I cannot get on my computer to access email or anything. Please Help. Thank you.

Hi, Welcome to GeekPolice.net!

Please download and run RKill.

Download mirror 1 - Download mirror 2 - Download mirror 3

• Save it to your Desktop.
  
• Double click the RKill desktop icon.
  
• It will quickly run and launch a log. If it does not launch a log, try another download link until it does.
  
• Please post its log in your next reply.
  
• After it has run successfully, delete RKill.

Note: This tool only kills the active infection, the actual infection will not be gone. Once you reboot the infection will be active again! Please do not reboot until instructed further to do so.
