Can't set IE11 as default browser

To Layback Bear - I checked that version and the two files have exactly the same contents. I will keep Bleeping in mind for future situations. Thanks

To ThrashZone- ran adwcleaner and it reported NO issues. as did Junkware Removal Tool v6.4. Hitman Pro
reported one cookie

To ThrashZone- for what it's worth, I had another bad slowdown this afternoon on my computer, which made me look at Task Manager. To my (uneducated) eye there was no stand-out issue, until I noticed (again) two
items under Processes usually run without any description. I went to the BleepinComputer site because I had
seen tabs for Startup And Uninstall List and found both, with a sigificant number of listings with status X; the
two items are csrss.exe and winlogon.exe. While I was typing this message, I went back to Task Manager listing and discovered TWO entries for csrss.exe.
A third entry is GFNEXSrv.exe, which is "not known" on the bleepingcomputer web site.
ps- if you would prefer to ask and not BE asked, let me know!

To ThrashZone- thanks for the update, sorry I didn't get back to you earlier, just became a grandad for the 4th time last night. I will work on the lists (as JPGs) and start running through the test steps and post results later.

To ThrashZone- OK, worked my way thru a couple of steps.
First, I signed on normally and and printed out the list of startups and services using MSConfig under a "Normal" boot but as JPGs as per original request.

Then, I logged in as Admin and performed the "Selective" boot and printed the same startups and services
using MSCongfig again. Note that Panda Antivirus and Zonealrm firewall refused to close, when I clicked on Apply or OK (tried both ways) before "restarting".

I tried the last step both as Admin and regular (non-Admin) users- the IE not default message window came
up for both users when I clicked on IE.

So now I'm on to the next step(s). Attached are before/after jpgs of MSConfig Startup and Service (non MS)
items

To ThrashZone- So after a brief timeout and re-reading STEP TWO, the results of STEP ONE say it's not
a non-MS item (unless it's Panda or ZAlarm firewall) so I'm not supposed to do further steps.
In further review of what is running, we have:
some of Panda, not all-
some of Zonealarm, not all
all of MS services-
some of Winpatrol- under Processes
Two Toshiba items (Config...) in Processes
.... and two items that concern me in Processes are...
csrss.exe and winlogon.exe- both of these never show descriptions or user name, both have been reported
as potential bad guys, and on my system, if I right-click on them to get "Properties", nothing happens;
on all OTHER entries under Processes, all show a Properties screen pointing to where the programs are
located. Even if I do a search on my C drive, nothing is reported on these two.
Anyway, going to go back to normal start-up- without the proper services on my touch-pad, I could really make a mess with this dumb tap=to=delete feature.
Hope you have something else for me to check, thanks
Wayne

To ThrashZone- thanks for the update
re csrss and winlogon- the Microsoft Community explains the what and why but there are two possible
differences: 1) that user states "I get two csrss processes and they do allow you to see properties and they
say they are from Microsoft- I can't get a properties window for either of these, and I can't even find the csrss
file on my C: drive (the only winlogon file I found is in a malwarebytes chameleon directory.
2) another :help" website lists over 75 versions of csrss.exe that have been verified as malware, trojans, etc.
see Startup Programs Database
Re the third party firewall- have used zonealarm firewall for maybe more than 10 years- from back in the days
when products built into microsoft were considered not as good as 3rd party ones, not sure that has changed today. I use winpatrol for similar reasons.
Point re cropping jpgs noted, I tried to do that,
So what's next!
