During startup, your ESET product will scan all the programs by default. When a conflicting program starts to run during the startup, your system scan takes longer than usual. You cannot cancel the startup scan once it has begun. When your system startup scan hangs or if it takes a longer time than expected, you may consider disabling the ESET startup scan. Disabling the ESET startup is not advisable, as it may expose your computer to risk. And it is advisable to uninstall the conflicting software from your computer.
It’s always advisable to disable the startup scan temporarily. Enabling the startup scan gives your system enhanced security.
