Can a blog spread virus ?

I came from those days where a text file will NEVER spread virus.

Most probably, a text file viewer will also NOT trigger any virus.

If I do NOT click or respond anything while viewing a file, I am quite sure I will NOT be infected by virus.

A blog is just a special type of web pages. A web page is basically just a text file on a server. You are viewing the content of the 'file' now using something like a text viewer called internet browser.

Unfortunately those simple days are long gone. Because internet browsers are also your file browser. Most often than not, the browser is the No.1 key element in your computer. Usually the First and Most important thing how your computer and you communicate. Without a browser, you literary can't use your computer. So your browser allows you to do almost Everything that can be done on the computer.

When you are just browsing a blog, you may be just reading of viewing some stuff. But your browser has done tons of other stuff you may never realize or will ever find out. So yes, virus could be spread in a blog even if you are just viewing it.
