Has my Google Chrome gone scareware?
Solution 1:
You could check the handy box and click "Proceed anyway"... But I recommend you figure out why the site was blacklisted first.
The site could have been the victim of a hack and may very well be serving malware that the moment or the recent past. Such blacklists are usually cleared quickly once the site is restored.
If your DNS resolution has been messed with (like by malware you may have already contracted) you may not actually be going to the site you think you are. Try using a web based lookup service to resolve the IP and compare to the one you get from the nslookup command on your box.
Solution 2:
It's not your Chrome, it's the Google safe browsing database which contains an entry for opengl.org:
Of the 22 pages we tested on the site over the past 90 days, 1 page(s) resulted in malicious software being downloaded and installed without user consent. The last time Google visited this site was on 2010-09-23, and the last time suspicious content was found on this site was on 2010-09-23.
Malicious software includes 1 exploit(s). Successful infection resulted in an average of 2 new process(es) on the target machine.
Malicious software is hosted on 1 domain(s), including hthexhe.co.cc/.
1 domain(s) appear to be functioning as intermediaries for distributing malware to visitors of this site, including dbkzbkz.co.cc/.
This site was hosted on 1 network(s) including AS21844 (THEPLANET).
Solution 3:
I'd like to add that Google's warning is not nonsense. Yesterday I was navigating opengl.org on an XP machine (via Chrome), when suddenly I got two alerts from my antivirus (Avira) about malware being found in the browser's temporary directory. I wasn't visiting any other websites at that moment.
