At first,fsp will report"Incompatible application detected“,but it wont happen another worse conflict when you ignore this
i think run two antivirus at the same time maybe will play a complementary role

Generally you should never install multiple antiviruses on the same computer. It can lead to problems such as slowdowns, the Windows desktop freezing, or even, as you've experienced, BSODs. In some cases you will get a BSOD during boot, so Windows won't be able to load and in other cases Windows will boot and BSODs will happen randomly. There are rare cases where an antivirus has been specifically designed to be able to used alongside other antiviruses, with Malwarebytes being one example, but aside from cases like this, you should never install more than one antivirus.

It's best to install one good antivirus and if you feel you're not adequately protected, do occasional scans with a second option scanner such as Malwarebytes, Kaspersky Virus Removal Tool (which of course you can't use anymore if you live in the US), or Norton Power Eraser. You could enable the realtime protection in Malwarebytes if you want. But it may cause slowdowns if you have two antiviruses scanning files in realtime.

Good,now i use kaspersky standard in my real computer,there are agents in china, and it is very convenient for me to buy,i only want to run 2 antiviruses to increase my protect,i remenber hitmanpro is a scanner too,and better than norton or malwarebytes
 
Installing Malwarebytes alongside any other AV is okay, conditioned you disable realtime protection of the other AV while scanning using MB.
Any other AV can be installed after Kaspersky with two conditions, disable K autostart with Windows and exit, and before starting K for on-demand scan, turn off realtime protection of the other AV.
Although Kaspersky antiransomware tool is marketed as an additional tool alongside any other AV, using it with Avast free ended by crashing Windows and reinstall.

HitmanPro has issues with false positives and based on posts here, it would seem that NPE has better detection rates.

I doubt that is the case. Disabling realtime protection usually will not prevent issues.

Use of K for on-deman scan is temporary (max for a couple of hours), if realtime protection of the other AV is off, no conflict is expected.
Of course turning off the other AV while scanning with K is the optimal solution; unfortunately, only K is providing this nice feature.

You will get conflicts, even if realtime protection is disabled. Because even if it is disabled, there are still drivers that are loaded which often will conflict with the other antivirus.

That is why K ability to turn off completely is the best solution; I wish other AVs could provide.

No recommend using two AVs at the same time. But if you want to test it, do it this way. No conflicts or BSODs and no impact on the system. :)

Even if you do that, there will still be some components loaded in RAM, which can cause conflicts even if they're not being used at the moment.

After checking running processes in task manager, I did not find any.
Actually, I have K free installed and turned off with AVG free running, and facing zero problems until the present time.

You won't always have issues, but you certainly can. As an example, once many years ago, a computer I was working on got a random BSOD. I installed BlueScreenView to see if I could find the cause. It was caused by a conflict between a Kaspersky driver and a driver for PC Tool's Spyware Doctor. Spyware Doctor had been uninstalled a few years previously. But, as is often the case when removing security software, some drivers remained.

I am not encouraging installing two AVs at the same time.
The reason for such a situation I have had K installed, but after installing Vivaldi as the main browsr, I was missing sufficient web protection by K as encrypted connection scan is disabled and K extension is incompatible with Vivaldi.
As you kindly mentioned, even uninstalling K will not completely remove its drivers; so I installed AVG free after disabling K autostart and exiting, keeping it as a second opinion scanner.
 
@roger_m & @Parkinsond MA only tracks the file being accessed, while K reads files dynamically. So if you copy malware and leave it in a folder or place it on another partition, MA will not detect anything, but K will detect and remove it because it performs dynamic scanning of the files on the computer. On a malicious or phishing web page, MA will block the page first, because it has access first, unless MA does not detect it passing through it, in which case K will block it. To make it easier to understand, remember that Comodo setting in the antivirus module that you change to scan on access and dynamically track? So, MA only scans on access and K dynamically tracks the files, in a few words, as if it were about execution that MA detects.
