My browser have been hacked.. or?

I just looked over my blog today and discovered a problem with my comment form. I've already installed and activated the Akismet anti-spam plugin so I don't actually receive the spam comments, but my comment form has been pre-filled with the following:

name: "Buy free viagra" email: "buyyouviagra@here.com" website: "http://www.freeviagra.com"

I have absolutely no idea as to how it happened. I haven't noticed any other strange use of the site. I only have two other pluins installed, which is published directly from Wordpress.org and I have checked the theme for modifications, but found nothing.

Now this is where it gets really odd. I tried checking my blog using Internet Explorer and Firefox but nothing wrong with those - it only happens when I look at it using Google Chrome. Now has my browser been hacked or something like that? I have only installed Chrome extensions from the Chrome Extension Gallry, so I suppose it should be okay?

My blog is www.simon-smith.dk by the way (in danish) - the problen occurs only when the comment form is visible (http://simon-smith.dk/teknik/programmering/backup-af-mysql-database-113#comments)

Hope someone can help me out with this..

How about other, similar sites? Or does this happen with this site only? – None – 2011-05-24T08:16:38.710

It must definitely be a problem at your end as the form is not pre-populated in any of the browsers I have tried including Chrome. Don't know how or why it is happening or what to do about it. – None – 2011-05-24T08:17:43.667

I've just checked a few other blogs, but didn't seem to happen on those.. – None – 2011-05-24T08:20:30.483

A bit unrelated, but Akismet can be rubbish in that it often allows spam through, and blocks legitimate comments. You might want to try a ReCaptcha plugin instead/as well. – Spectre – 2011-05-24T09:11:09.803

If Simon's PC/browser has indeed been compromised as he is asking then is that not on-topic? – James P – 2011-05-24T11:49:54.477

@James it is, reopened. – Sathyajith Bhat – 2011-05-24T12:03:51.803

There's a typo in your most recent blog entry title ;-) – Daniel Beck – 2011-05-24T18:41:43.490

I've created a commment on your blog - no problems so far. You might have some malicious extension installed.. Try to remove extension by extension or reinstall chrome.

Well I haven't installed any plugins recently and I've just deleted the one I had installed later than the last time I checked my blog.. – None – 2011-05-24T08:23:13.757

Try other browsers, or your browser in safe mode? – Spectre – 2011-05-24T09:11:44.047

I would suggest a virus scan of your computer with whatever anti-virus program you have, and maybe a re-installation of your browser... That's pretty much the standard thing to do, but it works most of the time.

And i really like your blog by the way. ;)

It's possible that this is malicious javascript coming from an ad (it could even be targeted specifically at Chrome).

Check out this SU question for some background and more possible answers. The asker had an issue very similar to yours.
