[UPDATE] Is Windows Defender Enough Security? - Comments Page 2

Security essentials, real time protection will not "turn on" on my win 7 PC. No explanation, just a window that says can't be turned on. Remedy? I have malwarebytes premium.

This is to follow up what I wrote yesterday about using MSE but, taking Bob's advice, I see I also have WD on my W7 Pro desktop. Well, today in reading an article about W10, It mentioned WD as an important tool to use. The screenshot in the article looked soooo familiar. Ha! It's the exact screen shot of MSE! So whatever WD is on my machine, I guess I just don't need it.

Regarding Microsoft patch for the latest CPU flaws (Meltdown/Spectre), here is a partial quote that may convice some to stick with Defender:
"Kevin Beaumont created a constantly updated online spreadsheet listing AV software compatibilities with the Windows patches. As of this writing, Beaumont says, Kaspersky, ESET, Avast, Symantec/Norton, F-Secure and, of course, Windows Defender work with the updates. Sophos, Trend Micro, McAfee, Bitdefender and Webroot don't as of yet (https://arstechnica.com/gadgets/2018/01/meltdown-and-spectre-heres-what-intel-apple-microsoft-others-are-doing-about-it/?comments=1)

Extract part#2:
...During testing, Microsoft found that some anti-virus software tries to do undocumented, unsupported things with kernel memory, and these things break when dual page tables are used...

Kaspersky AV, anyone????
