Hues of sepia that were in .NET Framework v3 and are missing in v3

[Guest six-h]

Not sure if this is the correct arena for my problem, but I would appreciate

any help, even if it is just to direct me to another reliable source of

knowledge.

 

I have had the most horrendous problems trying to remove a trojan infection:

- "trojanspy.banker".

It had trashed my Operating System to the point that I (a total novice)

undertook a factory re-set, which placed me back in late 2003!!!

 

Having surmounted several difficulties along the way back to 2008, I find

that "fings ain't wot they used to be" as the old song goes!

 

First time around, I installed the Microsoft .NET framework version 3, after

which Word, Internet Explorer, Photoshop and other software took on very

fetching background hues of sepia!

 

I immediately liked the effect as it made working with these programmes a

pleasure and was very easy on the eye.

 

Since downloading the current .NET Framework (version 3.5), this delight has

been denied me!

 

Does anyone know how I can restore it??
