Constant crashes and complete freezes

thanks for the help in advance

computer keeps crashing or freezing sometimes without kernel panic

It freezes or crashes every few minutes so i try to be quick

Before it just shut down often, now it constantly freezes

i run the latest version of EtreCheck and can show it here too

I already reset SMC and PRAM

Also it is good to note, that i have this problems for a 2 weeks now. The problem is that i need it right now till about a month time, when i could do some stuff to repair/ wipe etc it. I hoped to fix the issue and when i didn't watch anything fullscreen it nearly never freezed or crashed. But today it is freezing after a few minutes all the time. I gladly managed to upload my work files to the internet so i can potentially work from another device, but it is really Really uncomfortable as ill need to install many programs and so on there.

REport

While writing this thread it actually froze 3 times.

Also: both antivirus systems where installed after the shutdowns began and they found a spigot adware.

I also made a test and went manual fans on stat menu (that i installed to check weather my mac overheats) and realized that after the freeze the fans still work but my trackpad is not reacting, neither is anything else.

About the temps: although it can reach temperatures of 90 celsius on CPU and GPU I have never seen it higher and at least the freezes show me the last frame that the mac is stuck on being about 40-60 celsius overall.

Also it is interesting to note, that after running my mac in Safe Mode now about 20 Minutes passed without a freeze or shutdown
