Haute Secure is a security service developed by 3 former Microsoft security specialists. It’s designed to filter the web pages you browse and it blocks any websites known to contain malware.
It’s free for people to download and install on their computers. If you run a website they charge money so they can scan your website and alert you if it gets hacked and infected with malware.
Most of the good antivirus packages have had this feature for a long time, and it’s a good idea to invest in one of these.
If you really believe it’s not worth spending money to keep your computer secure and you insist on using free antivirus programs, then this will make a good addition since free antivirus programs don’t usually filter web sites.
