Although it's a bit late for you
You COULD have run HJT as soon as you were happy with your set up.
That way, at least you would have had something to compare against in your quest.

[always remembering to use HJT as and when you add / remove programmes]

As it stands, the bad guys use the SAME extensions as the good guys
so, you have to look at the whole name to begin the task of cleaning.

Macecraft have an easy to use cleaner that has a 30 day trial period.

Use it to clear out your registry, at least all of those marked as none existant / obsolete etc, this will give you a starting point. When the trial runs out, if you like it, you could always buy it, or just re-D/L ?

I've used it on dozens of PC's [mainly XP] and just clearing out the above mentioned has never resulted in a PC dying on me ..............

THEN you can Google for the remaining FILES........................
