How do I know if my PC has malware?

[TheRock]

Bit paranoid about this.

Are there clear signs that a system is infected, or can malware just sit there quietly?

Trying to figure out if I'm overthinking or if I should take it seriously

Both can happen.

Some malware is obvious:

Popups
Browser redirects
Unknown programs

Other types are silent and just use your system in the background.

Things to watch:

Unusual CPU usage when idle
Unknown processes
Slower performance for no clear reason

Three major tournaments, nine games, one win. The Tartan Army will remember the magic nights of qualifying forever. They will also remember feeling like tourists at the tournaments themselves rather than genuine competitors
