How many minutes after starting/turning on the PC does Avast Free look for new virus definitions updates?
Here Avast updates already while I login into Windows.
I don’t mean streaming updates but signature updates.
I don’t believe there is a set figure but it is meant to happen soon after the system start, as it may depend on a number of things system load, etc. Since I rarely do system restarts on this laptop it isn’t something that worry about.
I very, very long time ago (way back many, many years ago) there was a way to delay this - I have no idea if this is even possible or necessary now (.ini file and or location, plus self-defence module).
intsup.exe - this is the avast installation and update process - it runs very early on and does consume CPU activity as it checks for updates and applies them. Once this is complete it closes.I have delayed the instup.exe update function to start 5 minutes after boot, by modifying the avast5.ini file.
For a start you could try this, though it shouldn’t give that much relief - avastUI > Settings > Troubleshooting and enable the Load Avast services only after loading other system services.
I would warn against doing such modifications even if still possible (different file name and update process) users own risk.
