How seriously should I take these PUP.Optional.Startpage detections?

Recommended Posts

For whatever reason Malwarebytes has warned me about three of these in Firefox. I'm not really sure what's changed as I've download no new programs, nor have I altered anything in the browser itself, whether that's an extension or an add-on. In fact, nothing much has changed in my computer at all. I've run a full scan with Norton, and no threats are detected. I've noticed no odd behavior in the browser, nothing has been redirected, nor are there any popups or ads. Nothing's odd about my computer either. I'm not even sure this is a threat, but I figured I'd ask anyway as the Malwarebytes results aren't terribly detailed. Could this just be a false flag? Because there's almost no information to go on here, just the results saying that something's weird and that's it. Thanks in advance for any assistance.

Hello  and  :welcome:    @BxMary


My screen name is AdvancedSetup and I will assist you with your system issues.

Let's keep these principles as we proceed. Make sure to read the entire post below first.

  • Please follow all steps in the provided order and post back all requested logs
  • Please attach all log files to your post, unless otherwise requested
  • Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans have been completed.
  • Temporarily disable Microsoft SmartScreen to download the software below if needed. Make sure to turn it back on once the scans are completed.
  • Searching, detecting, and removing malware isn't instantaneous and there is no guarantee to repair every system.
  • Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
  • Do not run online games while the case is ongoing. Do not do any free-wheeling or risky web-surfing.
  • Only run the tools I guide you to use. Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • Cracked, Hacked, or Pirated programs are not only illegal but also can make a computer a malware victim.
  • Having such programs installed is the easiest way to get infected. It is the leading cause of ransomware encryption. It is at times also a big source of current Trojan infections.
  • If there are any on the system you should uninstall them before we proceed.
  • Please be patient and stick with me until I give you the "all clear". We don't want to waste your time, please don't waste ours.
  • If your system is running Discord, please be sure to Exit it while this case is ongoing.


I do see a few issues that need to be resolved. Don't worry though I can assist you in cleaning up the computer and getting things fixed up.

Currently you're running the following version of Windows 10


Platform: Microsoft Windows 10 Pro Version 2004 19041.264 (X64) Language: English (United States)

From the following link Microsoft no longer supports this version of Windows 10



As you can see, your version is on the very bottom of the list here as far as age.




I'm not sure there is a valid easy update from this version but we'll do some clean up first and I'll check on the best path to try to update to the latest version of Windows.

Give me a moment to put a fix together for you to run
