F-Secure Internet Security 2011 Beta, download is available
here
At 1st, I uninstalled avg anti-virus free edition, and installed f-secure.
Looking at a glance, it's very easy to handle and configure anti-virus policy for end users. I appreciate that user friendly interface anyway. I also like its alert. Every time I try to activate server (i.e. sshd on CygWin or something), it warns me in the way like "you are going to run server which allows the access from the Internet. Is it what you want?". So, I can easily determine if I should allow that service or not.
Unfortunately, when I run VMware Server Version 2.0 which had no problems with avg, any vm (i.e. ubuntu, xp, w2k) couldn't start running. Deactivating all f-secure functions in status console didn't solve the problem. Event viewer of win7 didn't give me easy work around. All VMs didn't run until I uninstall f-secure.
I reported it to bug report.
It's still running on virtual XP without any problems so far.
I hope the problems will be solved in the near future.
