Not according to Norton and McAffe(sp).
Our younger relative, our IT guy, told me to wait until Windows 10 comes. Then see how that works on my old computer.
If the HP doesn’t speed up, then buy the HP Mini Stream with Windows 10 and only use it for word processing, spreadsheets, bill paying,financial stuff, and to print from that computer and my Chromebook and Androids,
Then, continue to use my new Chromebook for web surfing and dropbox for photos to avoid viruses and other bs.
He hopes that with Windows 10, MS will get out of bed with the companies which want to use us for our data and develop a long healthy relationship with users like me/you. He thinks that Apple and Google have made MS wake up.
There’s a lot of stuff that Norton and McAfee don’t catch, because they mainly look for viruses. So, if you accidentally installed some software that loads you up with spam or something, they might not even look for that. Try this, the free version is very good at finding bad stuff like that:

Just be careful because they try to trick you into enabling the “free trial” of the premium version if you install the free version. That one will expire in 30 days so just decline that.
