Deepguard blocks games silently without whitelist option

Ewout

I've been using f-secure for years, never had this happen. I play games through Steam and lately it keeps giving me error 51, which means something killed the game .exe other than Steam. After a bit of experimentation I found that it's deepguard doing the blocking, turning on compatibility mode or disabling it allows games to run normally. But when I went to look in the list of monitored applications there was nothing and I can't whitelist programs that aren't in that list. That to me looks like some kind of bug.

 

I'm on windows 10 with the anniversary update. Affected games so far for me are Grim Dawn and Starpoint Gemini Warlords. Very different games which makes me think it's something that both games share that causes deepguard to act.

This is just a suggestion, as I'm not a gamer so I have no experience of this, but is there any difference when you use Gaming Mode in F-Secure?  You can access this from the system tray icon.

 

Unfortunately, you can't 'whitelist' applications through DeepGuard, unless it blocks them or asks for a decision.  That's a feature, not a bug.    Possibly submitting the games' .exe files to the labs for analysis might be of some benefit?

Hello,

 

Sorry for my reply.

 

Maybe there is not really "silently blocking"

 

Spoiler

I think that main trouble can be: "protection" under the games. Or like "steam"-design for protect this games (like against cheats/other).

 

And if it like that... basically DeepGuard do not block game (silently).

Just because DeepGuard (like HIPS-protection also) can to use hooks (for process).... so game at execute-action can to think that there is "modifications" and launch is broken.

 

Usually there is tips for use "compatibility mode" (which work in your situation also).
Maybe you also can to re-check about just "exclude"-list of real-time scanning (for some of designs.... this exclude-action valid for DeepGuard too). And to add there main .exe file of game.

But anyway.. probably most helpful step also is Support Ticket or just F-Secure SAS (for their re-check situation about).

Gaming mode makes no difference.

 

I have actually submitted the Grim Dawn .exe a few months ago when it did show up in the monitored list. At the time the problem was solved in a few days so I guess that false alarm was fixed. Now it doesn't show up in that list so I doubt submitting it helps.

 

Perhaps something in Steam is being blocked but then it would probably block all games and it doesn't do that. I'm out of ideas here.
