Yeah, and every company in the world has a complete copy of their systems in a test environment. GET REAL!!!
I have done work for many companies some as small as 10 users, others with as many as 1000. None have had full test environments, most have had no test environment, this included a Fortune 400 company. I even have a friend who works for a Bank that has one of the largest running Microsoft Networks in the world, and he does not even have a full test environment, he has 1 server to test on and a couple of computers.
I agree Kaspersky does catch things, but I think they (Kaspersky) are the ones who need to do the testing. It is OBVIOUS that they don't. They send out updates and then suddenly there are tons of postings here how things are now broken for MANY MANY users. Not just me, many!. Their documentation (or lack of) is also a problem. If it would have simply stated somewhere that this version is NOT supported for 2008 server, then I would not have installed it. Even the "2008 supported" version of Kaspersky does not say that is runs on 2008 server. I found that information here in the forum...
I have better things to do in my day than to test someone else's products for them. I compare this to Microsoft. Kaspersky has the same mentality, send it out now, we will fix it later. We are their beta testers, they are the ones using production environments for testing, not me. One thing that should have clued me in to this is how often Kaspersky updates. A recent article gave Kaspersky high marks because they averaged nearly an update every hour. Trend Micro (what I used to have) only updated on average once per day. Trend's reasoning of this was because they put every update through rigorous testing before release. I get the feeling Kaspersky does not do this.
As far as my testing goes, I did test this product on a sampling of my computers, about 5%, and installed it on one of my lesser important servers. It just happened to be a 2003 server, not 2008. And the computers I tested seemed to run fine and the 2003 server was fine too.
The issues with the computers now are mainly when they update they freeze (check the forum, there are MANY with this problem) and many of my power users have Kaspersky crashes often when using Firefox or IE. The 2003 servers are fine, my problem is 2008 servers. You would think they would update their installer to NOT install on 2008 server. That would be a simple fix. I have now installed the "supported" version on my 2008 servers and it seems to be fine.
Consider yourself lucky that you have not had issues yet. I bet you will someday.
We all dream of having a true test environment, but at this point in the real world, we are all just lucky to have jobs...

Ironic, my company is moving away from McAfee, because the protection it provides is absolutely worthless when compared to Kaspersky. We've been outbreak free since moving from mcafee, and I'm so glad we switched products. Haven't had any major issues since we switched, and the minor issues are all fixed in 1 phone call to support. Couldn't be happier.
About your 2008 woes...it's really your fault for not testing in a controled environment. Every single company in the world is going to tell you to test in a controled environment, because they don't want the liability of you screwing up your network/computers. When you find a company that tells you *not* to test products in a production environment, let us know so that we can all stay away. Even McAfee tells you to do product testing before deployment. I mean that's just good Networking...
