Having problems with MSE

I've had MSE on my Win7 and for a very long time and now for the past few days I have not been able to get definition updates. I keep getting this error message:



I even uninstalled MSE and installed newest download and it installed fine and then when I clicked on the Update button I got the same message.

Anyone else have the same problem?

I think I will have to get rid of MSE and go with AVG or AVAST. I'm unfamiliar with all these programs and can't be adjusting "this" and "that" to "try" and fix it because I might screw-up my computer even more.

(I was having 'similar' problem with not being able to access Outlook, but now thankfully I can access it. I notice some other folks were also having problems getting into Outlook. Maybe a glitch somewhere?)

 

It may not be the Microsoft Security Essentials software necessarily....Are you able to access Windows Updates?

Try running a Windows Update. Do you receive an error?

 

I couldn't get through to Critical Updates at the same time I couldn't get through to Outlook. At that time I couldn't update MSE either.
A day or two later I could get into Outlook and Critical Updates and it said I had 32 downloads.
(I had previously restored the computer to 4/14/2015, but I think it might have deleted some updates because now when I go into Critical Updates it mentions No History.)
I just went into Critical Updates now and see:



It shows MSE there so I guess it will update the MSE, but I wonder if I will be able to update MSE directly from MSE as I had been doing in the past.
I don't know if this make sense at all but it is confusing to me no end as a senior senior citizen.
Why is this happening all of a sudden to all these MS programs?
Why am I still unable to get definitions from within MSE?
Any help would be appreciated.

 

I uninstalled MSE and installed a new copy.

Did you notice that I now show an MSE update in the Critical Updates images I posted?

I clicked on it and it did download and I could open MSE and when I click on Update it says I have latest updates.

Now, when I ran a Full scan for the first time (with the new MSE) it took 3 1/2 hours. Does that sound "normal?"

Previously if I remember correctly, when I did a Full MSE scan it took about 2 1/2 hours. Maybe that was after the first Full scan.

Did a Quick scan and it took about 5 minutes ( - about 14000 items)

I am using Win7 (64bit) computer. (Items scanned = 1238468)

 

Thanks. I didn't know or I forgot that MSE support for all PCs will end in July 2015. Is MS going to issue a replacement for MSE? (I guess not, which will gain them more unhappy "customers."

I read this "There is no end of support even listed for MSE on Windows Vista or Windows 7 and Windows Vista will be supported through 2017 and Windows 7 through 2020."

I thought MSE support for Win7 would end 2020!

I think I will go with the Free AVG.

 

Then, when will MSE lose support on my Vista (32 bit) and my Win 7 (64 bit)?
