andrewduckerI decided to set up my development environment on my laptop, so I can play with stuff while I'm on holiday for the next two weeks.
And for some reason, unzipping Eclipse was being incredibly slow. Like, 300kbps slow. Which is about 100 times slower than it should be (SSD, i5 processor). So I checked what the resource monitor, to see if something was hogging the disk, or using all of the CPU.
And found that Windows Defender was pegged solid at 25% of CPU. Which, as I have four cores, meant that it was using all of one of them. This was annoying for two reasons: (1) 100% of a CPU and it still couldn't manage more than 300kB/s of scanning? (2) Only using one CPU? What is this, the 20th century?
As it happens, I have a Norton license with 3 devices available on it. And Norton underwent a major rewrite a couple of years ago which meant that it was actually pretty efficient (and easy to install/uninstall, which used to be hell). So I logged onto their site, grabbed a licensed copy, and installed it. Which took about three minutes in total, and worked seamlessly.
I then ran a quick scan (which removed 29 tracking cookies), restarted my laptop (to be on the safe side), and unzipped Eclipse again. Which got me about 30MB/s, while using almost no CPU at all.
I normally recommend Microsoft's own anti-virus to people, on the grounds that it comes with the OS, and seems to score reasonably well on effectiveness. I think I'll have to stop doing that (or at least offering caveats).

Yet I've seen a couple odd things on the Windows Defender window, so I guess I'll check it again a few times to see if it is really running right.
Perhaps disabling it would speed up my computer.

Date: 2015-07-07 11:06 pm (UTC)"In Windows 7, "Windows Defender" is an anti-malware application that's part of the operating system; it's not the same as "Microsoft Security Essentials", which is a stand alone antivirus that's manually installed, or the same as "Windows Defender" in Windows 8, which is basically the old Windows Defender and MSSE combined and actually is a fully-fledged antivirus application."
"Windows 7 Defender doesn't conflict with antivirus software because it isn't an antivirus application. ... The Windows 8 defender will automatically disable itself if another Windows-aware AV is installed. Neither require manual intervention to live happily with any modern AV app."
My computer is Win7, so that is why my security program didn't disable Defender.
