⚜️ The hard truth is that you can never fully prove your computer is malware free. But you can still stack the odds in your favor. I'll discuss why, the simple habits that keep you safer online, and what to do if something slips through.
⚜️ Knowing you don't have malware
It’s impossible to prove you don’t have malware on your PC — you can’t prove a negative. No anti-malware tool is guaranteed to catch all malware. Stack the deck instead:
- Make it difficult for malware to arrive by following security best practices.
- Make it likely that malware will be caught quickly by running up-to-date security software.
- Make it possible to recover, by having a backup strategy in place.
- May the odds be ever in your favor.
