Where the Sismscoldne.xyz pop-ups comes from
These Sismscoldne.xyz popups are caused by misleading ads on the webpages you visit or adware. Adware software presents unwanted advertisements on your computer. Some of these ads are scams or fake ads designed to trick you. Even the harmless ads can become really irritating. Adware can be installed accidentally and without you knowing about it, when you open email attachments, install freeware.
Adware software usually gets onto computers by being attached to another application in the same installer. The risk of this is especially high for various freeware downloaded from the Net. The developers of the applications are hoping that users will use the quick setup method, that is simply to press the Next button, without paying attention to the information on the screen and don’t carefully considering every step of the installation procedure. Therefore, it’s very important to read everything that the application says during setup, including the ‘Terms of Use’ and ‘Software license’. Use only the Manual, Custom or Advanced installation mode. This mode will allow you to disable all optional and unwanted programs and components.
