How to kill Lazarus under Windows 10?

[domasz]

Lately Lazarus and Avast are not cooperating nicely and every one and then Lazarus freezes. Then I just kill it, all windows close, but one process "lazarus.exe" is still running in the background and is unkillable in Task Manager (access denied).
Because of this process I cannot start Lazarus again and I need to restart Windows to use Lazarus. But I don't want to restart Windows every time this happens.
How to kill that lazarus.exe?

Better ask how to report a false positive issue to Avast....
(I still wonder why people are using extra virus protection when Windows comes with at this point in time the best one for free...) Hey, it is 2023!

I doubt Windows has a good protection. I have used Avast since Windows XP and it saved me many times.

I don't use avast, but it should be an exception/exclusion/white list somewhere in the settings. Add lazarus/fpc folder to the exception list. Lazarus will run much faster and without any issues.

It fails and show this message: "Error terminating. Access denied."

I did. Didn't help.

Well, congratulations to your antivirus program, he's still an asshole, I haven't seen this in practice for a long time.

I agree. I detects every compiled exe as a potential threat. And now it did something to Lazarus and I cannot kill it. Even "taskkill /F /PID 20544" doesn't work.

Generally Windows internal Defender comes out on top of the tests. Anyway, maybe simply exclude the relevant directories in Avasts'  configuration?

I also used lazarus along with avast, although it triggered for projects,but it did not detect as viruses

Not sure how to get to the locked process...

But, if you can use Lazarus 2.3 (the git main branch), then you can start lazarus with

Code: Text  [Select][+][-]

1. --skip-checks=SingleInstance

The option can be specified in the "lazarus.cfg" file, instead of being passed as argument.

And it will not mind the running instance.

Lazarus has settings in Tools > Option, if to allow more than one instance. But even if allowed, it still creates the lock. And if that lock is hold by a dead instance, then no new instance can create another lock.

The above options prevents even the creation of the lock. But it's 2.3 only.

In attachment is a "Lazarus.exe" killer program.
Beware, when you run it, Lazarus will be terminated without asking to save or such.

It is based on ZwTerminateProcess
