Cannot download from IE9 or open windows defender

Hi,
I've recently encountered a problem with my computer, whenever I attempt to download or even save anything from internet explorer I get the message "(whatever I try to download or save) contained a virus and was deleted". so for example if I were trying to download the latest Microsoft security essentials it would read "mseinstall.exe contained a virus and was deleted". I immediately thought to switch on security essentials and windows defender to check for a virus only to have this message pop up for both instances "windows cannot access the specified device, path or file. you may not have the appropriate permissions to access the item" any help would be greatly appreciated. I am running windows 7 Home Premium 64bit. Thanks

Click on type Internet Options inside Search programs and files search box and press <ENTER>

Click on the Advanced Tab

Scroll down to Security section

Uncheck Do not save encrypted pages to disk

Click OK

Then open up IE9 and try to download something

do not save encrypted pages to disk was already unchecked when I opened the window.

razzledazzle94,

Let's hope I am wrong, but, this looks like the new variant of the ZeroAccess malware.

Please go to the Farbar Recovery Scan Tool Download

Select the 64-bit version.
Save it to your Desktop.
Double-click the downloaded file to run it.

When the tool opens click Yes to disclaimer.
Press the Scan button.

FRST64 makes a log (FRST.txt) in the same directory from which the tool is run (Desktop).

Please provide the FRST.txt in your reply. <<---
The first time the tool is run, it also makes another log: Addition.txt
Also post the: Addition.txt <<---


Next, download Farbar Service Scanner

Save to the Desktop

• Make sure the following options are checked:
  
  • Internet Services
  • Windows Firewall
  • System Restore
  • Security Center
  • Windows Update
  • Windows Defender
• Press: Scan
• FSS creates a log, FSS.txt, on the Desktop.

Please provide the FSS.txt in your reply.

I cannot download this because as I explained in the OP, whenever I try to download or save from IE I get the error message

i've run both applications and it has saved the FRST.txt, FSS.txt and addition.txt but it wont let my ad an attachment to this post so I don't know how i'll show you them. there is a line in the FSS.txt that reads

Windows Defender Disabled Policy:
==========================
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender]
"DisableAntiSpyware"=DWORD:1

do I need to remove this?
