I recently encountered a popup that directed me to the link polystore9-servicebucket.cc. I'm really concerned it might be malware. I've already performed a clean install of Windows, but I'm not sure if that's enough. What steps can I take to confirm whether my computer is infected and how can I effectively remove any potential threats?

The nature of the popup matters. If it was just a Chrome notification, it might not be serious. However, if it appeared as a new tab and constantly showed up in the background, that’s more concerning. You're right to be cautious, especially since it's persistent.
If the popup wasn't from your browser and appeared solely in the background, it could indeed be harmful. Since you've done a clean install, you should be mostly safe, but keep an eye out. Running a full system scan with reliable antivirus software wouldn't hurt.

It was definitely like a tab—nothing else would load, and it kept popping up. I'm booting from USB to reset everything now.
