Hi, this is my first post and any help would be greatly appreciated. 
My daughters laptop started generating a number of error messages yesterday including Bitdefender which is now constantly generating Crash Information File Logs.
The main error messages appear when the PC is booted up "C:\Windows\System32\WINTRUST.dll is either not designed to run on Windows or it contains an error"
Various other error messages appear which include Bitdefender "Bitdefender Security Centre has encountered a critical error" the Crash Information file details "C:\Programdata\Bitdefender\Desktop|temp|BDCH_FJGFOKDBFFNGLIEPKPGMAODCLCMKNING_seccenter1353841891.dmp"
I have tried to use Windows Update to see if this would help with the system files but I get error messages when this option is selected and it wont allow Windows to update.
Various other reviews of the Internet imply this could be Malware infection. I did manage to undertake a full system scan using Bitdefender last night which found around 34 errors which appeared to be a variety of tracking Cookies.
Having looked at other posts I have undertaken a BDYS scan and uploaded it to Sendspace, I'm not sure if I'm supposed to post the link here or not so this is available if required.
As I noted above any help would be greatly appreciated.
