I am being told I need to install adobe 10 flash player, but it won't install. The download manager pops up and says it is but the sites still tell me I need it
Which Browser are you using? which sites?
If it's a "download manager" then it's possible that all you had done was download the Flash 10 installer, but not actually install it. you would need to run the installation program if that is the case. (this will require you to close all browsers and their windows).
It probably isn't very likely it's a residual infection- if you followed all the malware experts suggestions to the letter and followed through to the end, and they said you were clean- then you were clean. Also, this sort of symptom doesn't sound like something that malware would do.
