Google, You And Me In Front, Better Call Your Doctor

Somehow Google must hate me. In the past two days they have blocked around 10 to 15 sites of mine for “suspecious activity” and/or malware distribution.
I got some emails like this one:

Dear site owner or webmaster of gamesatfive.com,

We recently discovered that some of your pages can cause users to be infected with malicious software. We have begun showing a warning page to users who visit these pages by clicking a search result on Google.com. Below are some example URLs on your site which can cause users to be infected (space inserted to prevent accidental clicking in case your mail client auto-links URLs):

http://gamesatfive .com/
http://www.gamesatfive .com/

Here is a link to a sample warning page:
http://www.google.com/interstitial?url=http%3A//gamesatfive.com/

We strongly encourage you to investigate this immediately to protect your visitors. Although some sites intentionally distribute malicious software, in many cases the webmaster is unaware because:

1) the site was compromised
2) the site doesn’t monitor for malicious user-contributed content
3) the site displays content from an ad network that has a malicious advertiser

If your site was compromised, it’s important to not only remove the malicious (and usually hidden) content from your pages, but to also identify and fix the vulnerability. We suggest contacting your hosting provider if you are unsure of how to proceed. StopBadware also has a resource page for securing compromised sites:
http://www.stopbadware.org/home/security

Once you’ve secured your site, you can request that the warning be removed by visiting
http://www.google.com/support/webmasters/bin/answer.py?answer=45432 and requesting a review. If your site is no longer harmful to users, we will remove the warning.

Sincerely,
Google Search Quality Team

I am now trying to get some answer why this happened and how to get unblocked by Google because all users with Firefox 3.0 will be warned about this site and this could mean a loose not only in traffic now but also in trust. But please rest assured, I am really doing all I can to protect my websites. And I have no idea how this could happen.
