|Try running these free trials and remove all they find:|
1- Trojan Remover
2- Hitman Pro
I also noticed you didn't run tdss killer. You should run rkill.exe and then run Tdss Killer, you may still have an unwanted rootkit installed.
Also you didn't say which browser your were using, maybe try an alternate browser and see if you still can't use the problem sites you mentioned.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
