I would like to share what I have checked out on internet. This is about software that can pre-check the sites from any threats of virus, spywares and the like. It is very useful before you enter into the chosen sites from search list you will be given a status code if it is safe to explore or if there are some reports about the site’s spyware, virus, and malwares.
I am not promoting this site but I believe this will be of great help especially if we do not have good anti-virus software or nothing at all. You can search other known anti-virus software online with similar services offered as well.
Check this link and it will do the rest for you : http://www.siteadvisor.com
Should you have queries please do not hesitate to leave a message.
This is how the software works after you have downloaded it. It is free.
