Krakenfiles uses aggressive advertising to pay for its servers. If you manage to navigate the "Download" buttons (there are usually 5 fake buttons for every 1 real one), you might accidentally download a download manager or a browser extension. Many files labeled "sims 4 updater" on these hosts are actually just adware installers.
: A common mistake is selecting the "Documents" folder (where saves and mods are) instead of the actual game installation folder in "Program Files". sims 4 updater krakenfiles
