Would you know if your computer was a zombie?

It would go "coin Coin COIN!"...just kidding, bit of Scooby Doo humor never hurts.

Run a malware scan on it. Like from malwarebytes.org or trendmicro.com.

If your computer is grinding, especially when you are on the internet. If you receive tons of spam or popups, then you can be reasonably sure you are infected with malware. Just because you pay annually for a product like McAfee doesn't mean you're safe. I recommend a routine scan with a free tool like the ones I mentioned above to stay as clean and secure as possible.

Are you sure that's all it takes? I've never gotten a good answer as to how to detect if you are zombified.

I was worried that one of my computers was owned, because occasionally I get an error message saying something like there are two IP addresses on my computer. But I routinely do the spyware checks.
