Possible virus or corrupted chrome plugin on my mac. Need Help!

I made this post late last night that got 4 comments and then burried: http://news.ycombinator.com/item?id=4739517

It was titled 'Websites i've never visited are in my Chrome history. Mac virus? Corrupt plugin?'. Since posting it, the only plausible/reasonable situation was that i had google chrome syncing my history between devices, but...

1) I didnt watch hulu.com on any other devices

2) I havent been logged into chrome in a week: http://imgur.com/WmrAS

3) I'm the only computer to be logged into my account all month: http://imgur.com/NeL01

I'm thinking I either have a virus or one of my plugins is corrupted. That's the only thing I can think of. If it's a virus, well... a new mac virus in the wild would not be good. If it's a corrupted plugin... I only have 3 pretty popular plugins installed on chrome, so that would also not be good.

The device in question is an Early 2010 MacBook Pro running Mac OSX 10.8.2. My Google Chrome version is 22.0.1229.94

I am using the following Chrome Plugins:

- Reddit Enhancement Suite 4.1.3

- Hacker Face 5.8

- PageSpeed Insights (by Google) 2.0.2.2

I would really like to get to the bottom of this. Any ideas HN?
