Defense+ / Sandbox Help - CIS / Re: Testing HIPS blocking
« Last post by futuretech on Today at 12:46:51 PM »
I don't think using the clipboard was ever prevented in the past but if you can point to a version that it did work then it can be considered a regression bug that would need to be fixed. I do know that reading clipboard data is protected/block when you set block on direct keyboard access HIPS alert. But you can test using either comodo leak test or spyshelter test.

Build 6644 was supposed to fix this issue and was believed to work as others who had this problem with build 6606 said it was fixed in newer beta builds. So if you still have the issue using the latest beta version then it would be helpful to collect and share those dumps generated from the latest version so they can further look into it.
AntiVirus Help - CIS / Re: CIS virus signature can not update
« Last post by Metheni on Today at 11:23:39 AM »
Welcome to the forum thliang,

The base size variation during direct update and manual update is common because it downloads "*.z" file during direct update. So, base size difference mentioned here is not a problem.

For update issue, please try to locate "cavsedb" folder of CIS on your OS.

If the folder is hidden, please unhide using folder option. Refer enclosed images.

(For your reference: On updated WIN OS it is located at C:\ProgramData\Comodo\Cis\wpTemp\cavsedb)

Please check if there is any files in folder "C:\..\Comodo\Cis\wpTemp\cavsedb". If yes, delete them and try to update CIS and report if it works or not with error snapshot, if any.

Firewall Help - CIS / Re: Error during updates (COMODO Firewall 11)
« Last post by JitzyJT on Today at 10:31:10 AM »
Same here

Sometimes it updates successfully and sometimes it doesn't.

Also I'm getting a lot of "Unrecognized Files". The count keeps increasing even after I selected them all and looked it up in the cloud.

Also when I take a look at logs "Event Summary" I see update has never been performed.
Hello tesl and thank your for your bug report. Unfortunately this issue is related to a download manager or an video download extension and not to the browser itself. Please try to disable any extension that you might have installed for video downloading or any download manager and see if the problem persists.
Defense+ / Sandbox Help - CIS / Testing HIPS blocking
« Last post by sinclair on Yesterday at 11:58:18 PM »
I think that an action that should be blocked by HIPS is not being blocked. Is there a way to test HIPS like how antivirus scanners can be tested with dummy virus files? More specifically, I am able to use copy and paste to copy information into my web browser even when direct keyboard access is blocked. In a previous version of Comodo if I blocked direct keyboard access then I could not use copy and paste to copy information into my web browser.

1. uninstaller in safe mode

2. Delete all files others programs (zonealarm or others)

3. try install comodo internet security

Just finished.

 - ZoneAlarm isn't installed, I removed it months ago.
 - I uninstalled NetLimiter, even though the firewall was disabled - it's the only other security-related software I have.
 - I do have Hyper-V enabled on my PC, this is the only other network-related thing (attaches to adapters) I have that isn't standard - but it's out of the question for me to remove that.

The result has been the same as every other time I've uninstalled and re-installed over the past few days - the tray icon loads fine when I reboot after setup, but only once. If I reboot again, it doesn't appear and I need to reboot 5-10 times before it decides to load once.

I've tried to analyze the CisTray.dmp files with Windows debug tools but I don't know how to do that with non-Windows dumps (it lacks the symbols).

I'm going to just ignore it and go back to NetLimiter firewall for now. Hopefully I'm lucky enough that a Comodo developer can investigate the memory dumps eventually.

Bug Reports - CIS / CisTray.exe fails to start ~90% of the time
« Last post by cosmicdan on Yesterday at 09:40:00 PM »
A. THE BUG/ISSUE (Varies from issue to issue)
Can you reproduce the problem & if so how reliably?:
Somewhat. Happens ~90% of the time.

If you can, exact steps to reproduce. If not, exactly what you did & what happened:
1: Starting the PC and logging-in, OR;
2: Manually attempting to run CisTray.exe from the COMODO Internet Security folder
3: Only happens 90% of the time. I have to keep restarting the PC until it decides to work.

One or two sentences explaining what actually happened:
All worked fine for a while. Suddenly today I notice that the CisTray process fails to start, and I had to restart 5+ times before it would work.

CisTray (notification area icon) fails to start. Windows event log generates an Application Error similar to the following with every attempt:

Faulting application name: cistray.exe, version:, time stamp: 0x5b27c6d8
Faulting module name: ntdll.dll, version: 10.0.17134.228, time stamp: 0x6d15b6d7
Exception code: 0xc0000374
Fault offset: 0x00000000000f4d1b
Faulting process ID: 0x3dfc
Faulting application start time: 0x01d438eb47d13e62
Faulting application path: C:\Program Files\COMODO\COMODO Internet Security\cistray.exe
Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll
Report ID: 30a6b25c-0a55-49aa-8c38-43a88ecd837b
Faulting package full name:
Faulting package-relative application ID:

Note that the Exception code (heap corruption, apparently) and Fault offset are always the same.

Also note that I can still run cis.exe fine (the main GUI).

One or two sentences explaining what you expected to happen:
CisTray to work

If a software compatibility problem have you tried the advice to make programs work with CIS?:

Any software except CIS/OS involved? If so - name, & exact version:
Not that I know of

Any other information, eg your guess at the cause, how you tried to fix it etc:
- Made a new Administrator-level user profile to test in - same result
- Tried a RAM underclock. I have four sticks of 8GB RAM, which I know can give some instability in the CPU memory controller in special cases but didn't help.
- I will shortly try updating to the latest beta (.6644) to see if it helps.

Exact CIS version & configuration:
 - Exported config attached

Modules enabled & level. D+/HIPS, Autosandbox/BBlocker, Firewall, & AV:
Firewall only

Have you made any other changes to the default config? (egs here.):
Yes - I have added many firewall rules

Have you updated (without uninstall) from CIS 5, 6 or 7?:
     if so, have you tried a a a clean reinstall - if not please do?:

Have you imported a config from a previous version of CIS:
     if so, have you tried a standard config - if not please do:

OS version, SP, 32/64 bit, UAC setting, account type, V.Machine used:
Windows 10 Pro 1803 (build 17134.228), 64-bit, UAC enabled, Administrator account, not a virtual machine

Other security/s'box software a) currently installed b) installed since OS, including initial trial security software included with system:
a=NetLimiter 4 (using Limiter mode only, Blocker/Firewall function disabled).
b=I tried ZoneAlarm some time ago
No bundled software - custom build PC.

Note - the generated ZIP report is too large for attachments - it contains many CisTray memory dump files - so I've uploaded it to Google Drive instead:
