any risk of getting infected or attacked?

I just received an obvious junk mail and I foolishly clicked on their link of "unsubscribe"

I reached their page and it looks strange then closed it immediately.

Any risk of getting infected my computer??

Some said there are a kinds of virus that possibly clear all your files on your computer

 

Technically yes, but infection from this requires them to attack your browser with an unfixed vulnerability that does not require further user interaction. As long as your software is up-to-date that's quite unlikely.

 

This is precisely the time when a VM is great. Not sure about a dodgy link? Load it in a sandboxed VM. Once done, just restore from a previous, clean snapshot and you're good. I actually do a lot of web browsing this way - when run fullscreen, you only lose a small section of screen estate when using VirtualBox and the performance is the same - unless you're short of RAM.

I only include this as a side note because I can't really add to what Mr.Koala has already told you.

 

You can turn off all the hud elements in a VirtualBox window.

 

As it happens, I just worked this out, barely 5 minutes before I read your post! I'm loving the minimalist look it gives with the VM client's taskbar set to auto-hide.

 

Not all of these types are virus attacks. Some of these are just phishing for valid email addresses. Since you clicked it, you just validated your email address is real and someone is probably adding your email address to a list to sell to some spammer.

 

Sometimes those unsubscribe links are a trap to confirm that the e-mail address is still being used which will usually mean more spam. Best thing to do is never click any links in any of these spam e-mails.

 

And if you use a mail service with a spam filter, always click the "this is spam" button. It helps.
