Just updated to Big Sur on my 2015 MacBook Pro and it keeps shutting down after about 1 minute First update. Is it fixable?

Are there any AntiVirus, Disk Cleaner, Optimizers, Defrag, VPNs etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation.
