OK, there are a few things you can check out considering you're on Windows 10 and it appears to survive reboots.
Check to see if Deepbot is listed in background appsAs you mentioned that the Deepbot process is in a "suspended" state it could be possible that it was added to the background apps list somehow either automatically by Windows due to the amount you use Deepbot or by you accidentally. Any applications that are added to this list are run on startup in a suspended state (I believe) until they are needed. This in theory allows for quicker startup of programs as they are already in memory. In the case of Deepbot as the application checks to see if another instance of it already exists this won't quite work as intended due to the blocking nature of this check. You can find this list by going;
- Start Menu -> Settings -> Privacy -> Background Apps
If Deepbot is mentioned in this list flick the switch to off and restart your PC. This should then make the process disappear.
Try a different Task ManagerAlthough the Task Manager is great for basic day to day stuff sometimes something with more brute force is required to get the job done. Luckily Microsoft released another task manager which is more for the power user. This version of Task Manager, Process Explorer, can be found here
https://technet.microsoft.com/en-us/sysinternals/processexplorer.aspxDownload the program above, unzip the folder and run "procexp.exe" as an administrator. You should get a similar window to the following image.
Order it by Process name and search for Deepbot.exe. When you right click you will get a similar menu to what you'd get on the normal Task Manager but also a couple of other options as well, namely "Restart" and "suspend".
From here we have a couple of options. You could try pressing "Restart". This will kill the process and then attempt to start the program back up. Due to the process already being suspended the suspend option could be "Resume" instead. If this is the case try pressing this instead and it should, in theory, start the program back up.
