After updating to CIS 3.10.102194.530 I can not execute command.com. It fails with “Attempt to access invalid address.” Trying from the CMD promt the message is “The system cannot execute the specified program.” Before updating CIS it worked flawlessly. Both my systems are affected.
My main system:
Dell Dimension 8400, 32 bit CPU
OS: Windows XP Professional SP version 2002 SP3
Virusscanner: Avast 4.8 Home edition
Logitec, Soundblaster software
Dell Photo AIO Printer 922 software
D+ and firewall running in safe mode
Problem is the same for administrators and limited users.
I too seem to be having the same problem, after updating to 3.10.102194.530. Have run a virus scan in safe mode, came up with nothing. Will run a rootkit detection later. Hopefully it is due to comodo.
XP Pro SP3
Here is another thread about it. So am guessing it is Comodo.
I put in a bug report because of the similar problem in running “16 bit” applications (XP SP3, COMODO 3.10.102194.530), I can run cmd and get to virtual DOS window. When running old dos files, they come back with “the system cannot execute the specified program”.
I noticed that ntvdm.exe becomes a task, but wowexec.exe & opware16.exe did not start.
Also, when running FireFox I would have more than one instance in processes (task manager) and after closing the browser, firefox.exe remained as a running task. Even happens if FireFox is opened in safemode with all add-ons and plug-ins disabled. (It hogs about 95% of CPU time, requiring manual stopping of all firefox tasks). Same when using IE8.
I did shutdown COMODO, then stopped its services (Task Manager), but the faults remained. Next I went to msconfig and stopped the comodo services from starting, rebooted and still had the same problems.
Last step was uninstalling Comodo, reboot, and try opening, closing browsers, try running 16 bit applications. Guess what, they all work as should be. (and no more processes having to be stopped).
Was fiddling around, I can observe similar things happening as NeilG Now have four instances of ntvdm.exe running, I cannot kill any of them. Firefox lags for me, browsing is a problem. However, I can shut it down properly. Am running FF 3.5.
