My Laptop will not detect any disks! Help!

I have an Acer Aspire 5738 and I am using Windows 7.

A few weeks ago I downloaded some software and I noticed afterwards that when I opened my itunes a warning messagae would pop up and still does waarning me that the burner on itunes won't work and that it could have been caused by me installing otehr burning software, I hadn't been using any disks in my laptop at the time and never noticed that my laptop will not detect any disks either - my problem is that I cannot remember what software it was that I downloaded.
When I put a disk into my laptop nothing at all happens like that drive doesnt even come up in my computer.

So I just went in to my devices and my CD-rom device is showing a warning message - when I click for the device status this is what I get:

"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

I really am lost as to what to do next - any advice?
Thank you

 

This may be a malware issue. I would post a new thread over in the Malware Removal Forum and if your logs are clean, come back here and someone will help. Do you remember what software you installed?
