Certainly no one knows for sure what you yourself may be spreading, and if one does send a malicious link, it is likely that it directs one to a Linux server since most servers run Linux. Yet Windows is more vulnerable to infections mainly due to it being the most popular aside from mobile devices and servers. But as for me, your insinuation is baseless if not paranoia. No one has ever sent notice of any infection coming from me, and in 20 years of extensive Internet use by me alone I have only had 2 viruses (easily removed), one being W/98 and the other about years ago, and scans since always come back clean, by the grace of God, and I do not send executable files and only rarely a PDF I made myself. And I can keep tabs on what is running and set to run, and must sanction installations and have software that alerts me new attempts to run such things as Google updates and run once entries.
No, this does not mean some trojan, malware, spyware etc. can get past such unnoticed, but neither does it mean I am likely spreading stuff to others and that warrants using Linux with its restrictions (for me).
And while Linux malware etc. is less common and the system less vulnerable, yet, Don't believe these four myths about Linux security - Sophos ...
The main reason for infections etc. occurring is not because of a lack of Linux "vaccination" but how one uses hardware. (And you even have Kali Linux being used to bypass Anti-Virus safety.) According to TitanHQ analysts Top Blocked categories are :
1. Spyware and Malicious Sites >>> 60,000+ a day blocked!
2. Pornography/Sex
3. Nudity
4. Online Ads
5. Phishing/Fraud
6. Gambling
7. Illegal Drugs
8. Web-based Email
9. Social Media
10. Videos
These domains among others are to blame for at least 95 percent of the websites that pose a potential threat to visitors. - https://www.titanhq.com/safe-browsing-are-your-users-internet-habits-harming-your-corporation/
I use none of the above except for a rare use of 9, as in Twitter and FB (ugh!) and sometimes some worthy videos on Tubi.tv (see some of my recommended ones here) and YouTube.
And as explained, I would like to use Linux but for me it means a loss of functionality unless perhaps I take the time to learn a lot. I presently do not see the warrant for it.
I’m just saying that the biggest security threat with any OS is running default as an admin account. Same for Windows, same for Linux.
The wisest security prevention a Windows user can do is sign in with a guest account rather than the default admin account with admin privileges.
But most are not customizing as much as you do... :)
