Error Message; Windows - No Disk

[lancsman]

Since installing F-secure on my system I keep getting the following error message

Exception Processing Message c0000013 Parameters 75b6bf9c 4 75b6bf9c 75b6bf9c

for about 10% of all Bot checks.

Any ideas?

Hello,

Please have a look at this link:

This is a known problem which can occur in Windows.
Plug & Play devices could cause wrong drive letter assignments in Windows.
So please try to reassign the drive which cause the error.

The error message does not state which drive is missing. How can I find this out? and why did it start after installing software (F Secure). I did not have any issue when I had Norton Installed.
