Need help in cleaning my PC of MALWARE

I have a piece of Malware that is telling me that for 50 bucks I can clean my PC of W32/blaster.worm. Problem is this malware is blocking all attempts to download or execute anything. I can not download valid anti-malware or virus software because I think it is being blocked by this Malware. At a total loss. posting.php?mode=post&f=11#

What type of Operating System are you using (XP, Vista, Windows 7, Windows 8) ???

Win 7

In that case, we should be able to run a scan from Recovery Environment, since your infection should not be active in that mode, and therefore should not interfere with things.

• If using a 32 bit version of W7 ... Download FRST to a USB flash drive.
• If using a 64 bit version of W7 ... Download FRST64 to a USB flash drive.
  
• Plug the USB drive into the infected machine.

Boot your computer into Recovery Environment

• Restart the computer and press F8 repeatedly until the Advanced Options Menu appears.
• Select Repair your computer.
• Select Language and click Next
• Enter password (if necessary) and click OK, you should now see the screen below ...

• Select the Command Prompt option.
• A command window will open.
  
  • Type notepad then hit Enter.
  • Notepad will open.
    
    • Click File > Open then select Computer.
    • Note down the drive letter for your USB Drive.
    • Close Notepad.
• Back in the command window ....
  
  • If using the 32 bit version of FRST type e:/frst.exe and hit Enter (where e: is replaced by the drive letter for your USB drive)
  • If using the 64 bit version of FRST type e:/frst64.exe and hit Enter (where e: is replaced by the drive letter for your USB drive)
  • FRST will start to run.
    
    • When the tool opens click Yes to disclaimer.
    • Press Scan button.
    • When finished scanning it will make a log FRST.txt on the flash drive.
• Next
  
  • Type services.exe;explorer.exe into the Search: box in FRST
  • Click the Search Files button.
  • FRST will scan your machine once more, this time looking for files.
  • When finished scanning it will make a log Search.txt on the flash drive.
• Close the command window.
• Boot back into normal mode and post me the FRST.txt log and the Search.txt log please.
