Help a newb

Okay, I'm not a complete newb. I know enough to know I hardly know anything. I use my computer mainly for online gaming. Yesterday, my wife went to a site Vintagesociety.com (I think that was the domain) from a link to a fashion site. This site appeared to do something with adobe acrobat. The next thing I know Mcafee firewall is saying that a couple of new programs are trying to access the internet. I blocked these. The new programs trying to access the internet were go.exe and 12345.exe. I believe these were just randomly named files by hijacker

My browser has been hijacked. Links are redirected to random sites. Also I'm blocked from real anti-virus/malware site. I'm either blocked or it pulls up some b.s. antispyware site. The computer also started running very slow. I ran mcafee virus scan. It didn't detect anything.

I went to add/remove programs and I saw one that said simply, "otto", which seemed unfamiliar. I clicked on the "change" button and it seemed to lock up and not do anything. I suspect this may be part of the changes. It may not be.

I'm using my work computer right now. So my questions:
How do I determine what I'm fighting?
How do I get rid of it?
Anyone brave enough to go to vintagesociety.com and see what I got? (I think I got the rogue domain name right. If that's not it, let me know and I'll ask the wife again. I'm certainly not visiting it on this computer).

If I have to download anything, I'll have to do it from this computer (work computer) and take it home to install.

Thanks in advance for your help. I'm at a loss.

Thank you for the starting point. I'll go through this and report back what I find or can't find.
