Hello, I've followed all the steps in the preliminary removal instructions. Attached are my HJT, AVG anti-spyware, and ComboFix logs. (I can add the other logs -- VBG etc. -- if it will be helpful.) AVG anti-rootkit indicated there were no installed rootkits on my computer. (I can see from the AVG log the probable root of my problems. Ugh. I've learned my lesson in that department...) Thanks in advance for your help!
