Malware Warning (resolved)
I have been informed that my site was producing malware warnings from Google. Google web tools reported that some malicious ads were possibly being served through my OpenX ad server. OpenX has been removed and the database deleted. You would have only encountered the infected sites if you had followed one of malicious ads and landed on a site delivering the malware. But since openX is gone for now, tuxmachines.org is completely safe as are the google ads that remain.
I just hope google will remove the warning with their next crawl. I have requested a review. Until then you can safely add tuxmachines.org to list of safe sites to avoid the warning.
