After running a virus, should you instantly shut off the pc?
I recently run some malicious exe and my reactions were to quickly shut off my pc via the psu switch after realising the virus was acting too fast for me to try to manually stop it. Then I booted up, quickly went to safe mode, did anti viruses, manually reviewed files etc etc

But is this a good idea?
My thinking is, a virus needs some time to intialise itself. If it doesn't have that time, perhaps it would be unable to "upload" it's virus code to my computer or something. So shutting off the pc gives me time to think and help prevent the virus from doing much damage -- but these are my uneducated thoughts.

Binary code within a virus can act as fast as your computer and can unpack all its potentially harmful files and take-over your computer (and its permissions) before you even consciously think to react appropriately. Think to remember well that the human-mind does not operate as fast as a computer so what has happened has likely already happened before you could of reacted.

What I would do is run a full security scan before shutting it down as it might lock you out from the system depending on how powerful and well-designed the virus is. After you've done a full security scan, then I would shut down the computer and run it in safe-mode and do another full virus-scan.

If there's anything on your system that is acting out-of-place or has any unusual and persistent issues that the virus scanner couldn't identify then you either have to resign and do a full-factory reset which will make you lose all your files however fully remove the computer of all its contents (including the virus), or take it to a computer shop unless you think you can identify the virus and deal with it yourself (which I wouldn't advise).

I haven't dealt with any viruses in a long-time as I tend to be very conservative and careful with what packages I download and to what permissions I give it. Be wise next time to test any programs on a virtual machine before downloading it through your computer and don't give it full administrator permissions unless you're absolutely certain that its contents are perfectly safe and are fully trustworthy to deem with those special admin-granted permissions.

Do not plug in a USB and try to save any files. Your private files might already be corrupted by the virus and harbour a possible infection-risk to any USB or external hard-drives that you have connected to the machine. That's why it's a good idea to backup your files.

Just for the sake of clarification, allow me to make a remark--

I do genuily think a .exe takes some seconds to get itself fully initialised, like when I go to open steam for example it takes some seconds to launch. When I launch a game it may take a while before I see the loading screen.

Steam and games contain way more instructions and more data (especially games). Simple malware can cause an exponentially larger difference much more quickly, since a lot of harm can be done in a fraction of a second with minimal instructions. In any case, it varies about as much, since ransomware can take an entire day depending on the hardware, for example.
