I always suspect a kind of spying me via internet. It's not very safe place, you know. I've received mails telling me to fill in my personal dats to get a money prize and so on. So i read something about viruses, fishing, scam every day, something like that https://www.safetydetective.com/blog/what-is-phishing-and-how-to-protect-against-it/ (I recommend this author, she knows what she writes about). But I wonder if there are some tricks applicable exactly to my Dell 3500 to improve its security. Any ideas?
