I can’t get rid of this Trojan- and I’ve tried all the suggestions made by users in previous posts!

I have:

Scanned with Malwarebytes Anti-Malware
Scanned with AdAware SE
Scanned with XoftSpy SE
Scanned with Spyware Remover

Attempted to scan with SuperAntiSpyware (I already had this program) and even re-installed it but it just won’t open for some reason! (I think the trojan has somehow hacked into ti?)

Also attempted to scan with Spybot Search & Destroy but got the same result as above.

In addition I’ve run smitRem a program suggested somewhere…

I’ve run this in normal mode. AND in safe mode…

AND NOTHING WORKS!

Please help! Any other suggestions!?
P.S. Reformatting I consider only to be the very last option in this! It’s a bit difficult since I don’t have the original windows CD- unfortunately I’ve moved 3 times over the past 2 years since I bought my PC and somehow it’s got lost along the way!

So if there’s some way I can delete it manually from the registry, that’d work too!
Again, I stated that I already have Spybot Search & Destroy, installed it- now twice- and it won’t even start
- I’ve also used Smitfraud, sorry I called it SmitRem in my original post. That didn’t work either!
