Suldo dot click Attempts Fake Scares to Push Ads
Suldo dot click is a misleading website of the "fake virus warning" variety. Similar pages will display outrageous and scary but always very fake warnings about virus infections or potential issues with your system.
In the case of Suldo dot click, it will display images styled to resemble the interface windows of a popular antivirus application. Of course, this is a fake, just like the messages inside those fake windows.
Similar sites will try to scare the user with misleading threats about half a dozen viruses found on their system or some sort of imagined dangerous website that they visited.
Remember that those warnings are always fake and the website is trying to trick you into doing something you would not want to do. A web page cannot know the protection status of your system. Simply close similar misleading websites when you run into them.
