Thanks John.
Pcflank is a site dedicated to security and testing software.
You are welcome. 
Here are some URL Scanner Reports for those two URLs:
The first was detected as possibly malicious by a few of the scanners.

The second one as well.

Probably one or more websites hosted by these had some malicious content within the last month; hopefully the Comodo Team will research this for you.
Good luck.
Thanks :-TU
You are welcome.
Hi. I’m blocked out of http://www.cityoftempest.net/ and I believe it is safe because its a simple game forum and other players don’t have any problem with it.
So far it does look clean according to these URL scanners, so hopefully the Comodo Team will look into this for you, good luck.

Can you please add www.xa.yimg.com to the safe list.
This is the site that yahoogroups uses for it’s online documents. I haven’t had a problem accessing it via Trend Micro but since installing Comodo I can’t access. I am going to have to uninstall Comodo if I can’t sort this out as I need the site access for work.

For now you could try another DNS Service, which may or may not block it.
Norton DNS

The following sites have been giving me trouble for about a month now. They almost always fail to load and I get a browser error (not a CSD error) “server not found”. This happens with IE, SeaMonkey and Firefox. If I set my system to automatically select a DNS server, the pages load fine. I flushed my DNS cache, but the problem persists. They’re the only sites I’m having trouble with, while using CSD (which I’ve been using for quite a while).

Interesting, I am currently using Firefox and Norton DNS, and that URL works for me; sounds like a Comodo DNS issue possibly.

Yep! It’s a Comodo DNS problem! I changed my DNS to Norton DNS and the sites load fine! Thanks for the tip on the Norton DNS. I’ll use it until Comodo fixes the problem. 
You are welcome, good luck to you and the Comodo Team, hopefully they will fix the problem soon.
Hi I can not access the pictures in yahoo groups. An example element for the image is
so I think the site that is OK is http://xa.yimg.com/kq/groups
Hello,
That website and/or a URL associated with it has been detected as possibly malicious by a few URL Scanners:
http://www.urlvoid.com/scan/xa.yimg.com
http://www.virustotal.com/url-scan/report.html?id=aa2f2b8e1552826747a3d877f89624b0-1305717925
http://www.avgthreatlabs.com/sitereports/domain/yimg.com/
http://siteinspector.comodo.com/public/reports/34613
Maybe somehow that could be part of the problem and/or a website issue and/or a Comodo DNS issue; I am not sure, I did not go to the website to test it myself, since it may/might possibly be malicious.
I know I sound like a broken record, but if you feel like experimenting, you can try accessing the website using Norton DNS and see if you have the same problem; that can help you figure out if it is a Comodo DNS issue or not, possibly.
