I just tried to open www.pcd.co.th for the first time this year and I get a Reported Attack Page! warning.

Both my laptop and netbook are dual boot Ubuntu so would it be safe to open in Ubuntu?

It's www.pcd.go.th

I get a Google warning too, this what they say here http://www.google.co...cd.go.th/&hl=en :-

I suspect you'll be just fine in Ubuntu and for that matter Windows if you have decent antivirus and anti-malware applications installed.

I was geting this same warning message for a couple of weeks back in January. Then the warning went away unil this past week when it suddenly appeared again. The data (at least for Chiang Mai) has not been updated since January 31st 2012.
