All notebooks I purchased and owed since 2013 (the 2 Toshibas and the new Vaio) came with default McAfee antivirus. Better said: they came with a 60 days trial McAfee. The point is McAfee is a commercial antivirus: as the trial period expires, we need a subscription to go on using the program. But I didn't find the default and free Microsoft defender worse than McAfee, this latter even well known to catch false positives. Combining defender with free standalone virus removal tool and free standalone antispyware, it worked very well all these years long. To remove McAfee (and so avoiding the conflict with defender), I always used MCPR free tool. This is the main tool to remove all McAfee products, avoiding records left in the registry (it usually happens after a control panel removal). MCPR used to resolve McAfee removals even in 2013 or 2014, when Windows system resulted unable to remove McAfee antivirus (and many users were desperate about that issue).

Such tools are very useful. Often Programs are uninstalled and entries still persist in the registry (regedit).

Yes, I know, I too had again and again the need to modify the registry opening regedit and deleting codes (not suitable for beginners, if the wrong code gets deleted, they may need a new pc, as the wrong deletion may transform the pc in a paperweight ).
