Security Plus: Sometimes it's hard to say whether a link to a website or a domain is secure or not. While the url of the site may sometimes give you clues, you can never be sure even if you have visited thousands of times the same link.
What you can do in this case is to check the site in databases malware. There are many services available online that can do this, such as Web of Trust.
Many of these services have one thing in common: they provide you with a result. But if you prefer more results, as they improve the chances of a correct assessment, then you can use services like Virustotal.
Just visit the service, and paste the url in the box. Wait for the results to appear on your screen. Although this service is quite useful, the process takes a lot of time especially if you check connections regularly.
Here's where comes an add-on for Firefox. The Security Plus is an extension of the program browsing Firefox adding a new entry to the menu of right click. Registration allows you to check a link directly on the Virustotal service.
This of course is done without having to leave the site after the results appear on the same page with a small overlay on your screen.
The results show whether the website you are connected to is pure or not with all 64 services supported by Virustotal. The extension will scan all selected links.
The main advantage with the Virustotal page is that the results appear on the same page and not on a new page that opens when you start the scan.
If again useste Chrome you can see it VTChromizer. Internet Explorer users can try it out Internet Explorer VTExplorer. Both last extensions open the scan results on a new page.
