Is that website safe to go to?

6/14/2017

 
Have you ever wondered if a particular website that you're going to is safe?  Could it be a phishing site, or could the site download a script to your computer?  Before you hit that "enter key" and connect to the site, there's a tool that you can use to check out the safety of the site.  I don't recommend using this tool for every site that you go to, just the odd one that you might be suspicious about.  Open this website https://www.virustotal.com/  and copy the URL of the suspicious site that you want to check.

 That's all there is to it.  If you get a favorable detection ratio result, then you shouldn't be worried about going to that site.  You can also scan a suspicious file on your computer in a similar way.  (There's an add-on that can be installed to your web browser called WOT (web of trust) that automatically notifies you of a dangerous website. I don't recommend this, as there has been some questionable things that the website owners have been doing with data extracted from the computers using this add-on.)
