When I was installing CIS 5 on my computer, (Win 7 Home Extended, 32-bit version) I had Avast 5 already. After installation of CIS (I’ve used web-installer) and reboot, programs in autorun were working properly, but no other programs (e. g. Firefox, Foxit Reader, Total Commander etc., even Task Manager), except explorer, could be started by user. Trying to start them led cursor to go to “background mode” and – nothing. System continued to work, D+ made no notifications, but applications were unreachable.
I’d uninstalled Avast 5 – no changes. Turning off D+ and/or Sandbox and/or execution control and/or monitoring left everything unaffected.
The problem is solved only if deactivate the defence + permanently (even without reboot).
I think that CIS has conflict with internal windows security settings. But i don’t know what should be changed.
Had somebody encountered with similar problem? Help, please! O0
look if you have blocked files and if thereare files that are always sandboxed.
CIS —> Defense+ —> Computer Security Policy. you have to check blocked files and always sandboxed
Can you tell me how big your file vendor n file? this is how you check the vendor files (they should be some kb) Now do these steps: desktop —> My computer —> program —> comodo —> comodo internet security —> database.
and if you have problem with the vendor list then look below.
Hey all!
here is how you solve this how you solve you “Trusted Software Vendors was lost” problem.
Download the attached and extract it on your desk (so that you have it visible).
restart the computer and press F8 and select safe mode.
Now do these steps: desktop —> My computer —> program —> comodo —> comodo internet security —> database. Keep database window open, now you delete all files besides the files that are called pending, now copy what’s in database_CIS in database.
The attached folder has the database from a clean Win7.
It is since second reinstall of CIS. Previously I removed Avast 5, but it was of no use. So I decided to install it again, that’s the source of the second warning.

Thanks again for advice, I tried it and my Trusted Software Vendors became much bigger, but the situation remained unchanged
Never mind, I like COMODO for innovations and bugs necessarily come along. The point is that I can contribute to make it better (even without coding skills ;D )
as for uninstall/reinstall – I’ve done twice – no result…
P. S. I’m really sorry for troubles that I make, but I’ve used CIS with D+ for almost 3 years and like it…
It looks like there is another program or left over from previously installed security programs that may be in the way.
What are the security programs you have running in the background now? What security programs did you have in the past? May be left overs of previously uninstalled security programs are acting up. Try using removal tools for those programs. Here is a list of removal tools for common av programs: ESET Knowledgebase .
Otherwise do a Google search with terms “removal tool” and * name of product or vendor*.
So… My system was installed in September and since then Avast was the only anti-virus/anti-malware soft. Using half an hour and these instructions I’ve done the following (++ means reboot):
Avast uninstall ++
Cleanup with avast cleaner ++
Manual & CCleaner cleanup, D+ enable ++
No use. D+ disable, uninstall of CIS ++
Manual & CCleaner cleanup ++
CIS install ++
After reboot all files in “Startup” worked properly. D+ added them to “Trusted files” list. When I tried to launch Total Commander, the warning appeared, that app was sandboxed. After clicking “Don’t isolate it again”, warning disappeared and nothing happened. No other programs except explorer could be launched (and no warnings about them were seen). BTW, CIS added TC to “Trusted files” list, but obviously it had no effect.
I still think that it is conflict between CIS and Windows security settings…
No, I hadn’t made any changes.
May it be conflict with UAC?
Should I post appropriate logs here (for UAC) ? Or, generally, should I post any system info for You to see if my suspicions are right? If so – what info and how to get it?
Many thanks
we caused this by a dodgy update…really sorry
