Virus Removal Guideline

‘Every time I'm on yahoo.com or in my yahoo email accounts I get a pop-up disguised as something I've downloaded (or maybe I did download it??) and says:
Do you want to open or save get-user-id.js from ad.yieldmanager.com?
I have looked at a lot of posts dealing with this issue, but I'm thinking that I need to ask specifically for my computer. I've done all that I know to do which is running a scan through trend micro and deleting temporary internet files. I also tried something I found on ehow which was blocking ad.yieldmanager.com.’ – quoted from one of its victims.
