I've been messing around on PC since the Counterstrike days in highschool. For gaming i never owned a console, was always into custom PC. I always enjoy learning new things regarding research, new hardware.
On GAW I have learned how to archive, meme, scrutinize more strictly and find better primary sources among many other things. I would like to learn more from my brethren here.
I will share a few. Keyboard shortcut basics:

We are all thirsty for knowledge!
Oh, re: antivirus.
In 97% of use cases, an antivirus is pointless at best and at worst sucking up RAM, compute time and storage speeds.
2% of those use cases are business antiviruses where you don't have a choice of using it.
1% are throwing it on elderly PCs that somehow have 390 taskbars and a massive porn collection from sketchy sites with Windows Defender turned off.
If you're on Windows, Defender does a really good job (surprisingly) when combined with common sense and things like uBlock Origin or other adblocking plugins.
Most malware nowadays ends up being through downloaded .exes that are pretty easily avoided unless you irresponsibly download and open every program you come across without knowing what to look for and how to handle it.
