3) If you have downloaded a file or setup and after clicking it, if you notice that it is taking very long time to install or is responding weirdly stop the process right there, if it is not closing use task manager to close it and delete the file permanently, it was probably installing a backdoor in your computer.

*If you are downloading a file and you open it and then you see it much time to open and install then you should stop it, If it  is not then you should close it by task manager and format this file permanently because it may be installing backdoor some trojan in your device.

.If any software suggest you to check this thing or suggest you to deactivate the antivirus then yo should check this point *

That software should must be very famous 
you check all the comment about that software by which you can get to know about that software 
Download from official source only. 

If you check all the thing is right then you should download the software with the antivirus and then see what happened if you download that software with enable antivirus then it is clear cheat. If you get any trojan like adware,virus and backdoors and worn then you shouldn't download this software..

It is not necessary that hacking software is detect all the security or trojans but you have to take risk.....*
