Hi Naga,
Tested and reproduced it on Win7.
I bet you'd see this in any many personal FW / Antivirus, to prevent
a malicious software from manipulating it via the mouse (and disable
it, for example).
I'd try with ZoneAlarm
(http://www.zonealarm.com/security/en-us/zonealarm-pc-security-free-firewall.htm#)
for example, which I know has such protection.

Seems you are right. So the only option we have is (auto)fallback to
server mode / usbtablet for such apps?
If you can do it automatically, I guess so.

I don't have a patch yet for solving it, but you comment out the
line:
//ret = _running = false;
so vdagent won't exit, although mouse will not be effective on such
apps.
If it's a must, meanwhile you can always switch back to server mouse
mode by stopping vdservice.
You can also use usbtablet in case you don't need vdagent
functionality
(multi mon, c&p etc.)
I'll update you when I have a patch ready (currently not top
priority).
Regards,
Arnon

Hi Arnon,
Have you checked installing kaspersky trail version? Here is the
eror that causes vdagent.exe to be terminated abruptly.
VDAgent::send_input::SendInput failed: 0
VDAgent::run::Agent stopped
I've checked integrity level of Kaspersky UI process and it is
lesser than VDAgent.exe
Thanks/Naga.

Hi,
VDAgent in Windows 7 guest gets terminated when mouse hovers on
some applications like Kaspersky Anti-virus tool. Noticed
SendInput Windows API fails whenever any mouse operation performs
on this tool. "handle_mouse_event" method returns with failure
due to this and causes VDAgent to terminate.
what's the error logged in %windir%\temp\vdagent.log? look for
"SendInput failed: ...")
Initially, I thought it is UIPI ie., Process Integrity Level issue
and observed as follows:
VDService with SYSTEM a/c creates VDAgent with SYTEM a/c
Kaspersky tool is service-based app with SYSTEM a/c creates
process to handle UI with logged-on user and with 'Medium'
Integrity level.
Don't understand why SendInput API fails even VDAgent with higher
integrity level than Kaspersky tool?
Is there any other way to make VDAgent works for all applications
installed in windows guest?
will give it a look and update you accordingly.
Thanks\Naga.
