Tech Support Guy System Info Utility version 1.0.0.4
OS Version: Microsoft Windows 10 Home, 64 bit
Processor: Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz, Intel64 Family 6 Model 158 Stepping 9
Processor Count: 4
RAM: 12196 Mb
Graphics Card: Intel(R) HD Graphics 630, 1024 Mb
Hard Drives: C: 918 GB (846 GB Free);
Motherboard: Dell Inc., 07KY25
Antivirus: Windows Defender, Disabled

My post is going to be twofold! After running the SysInfo utility I see Windows Defender is disabled. Could that be because McAfee is running? If not, how do I enable Windows Defender?

Then my next question is can I run two versions of Thunderbird on the same machine? I ask that because my old computer crashed making the need for a new one, which runs Windows 10. I downloaded Thunderbird Beta, which probably wasn't a good idea. Then I found the version of Thunderbird I had prior. I have a back up of all my addresses for the old version but cannot figure out where to locate it in the newer version of TB, prompting my question, can I run two versions of Thunderbird on the same computer?

Thanks for any help! :)
PS: Old Windows version was 7, if that can be of any help!

Yes, McAfee most likely disable Defender.
You do NOT want to run both Defender and McAfee, as they will fight each other and really slow down your system. My choice would be to uninstall McAfee.

As for Thunderbird, I have no idea.

Thanks for the suggestion!
Yeah, McAfee came on the new computer and Dell always loads McAfee, which I've never liked McAfee (too confusing). I have Malwarebytes, do you know does it conflict with Windows Defender? It didn't seem to on my old system.

If it is the new 3.xxx version, yes it includes an AV, so it should not be run with Defender.
