MS Security Essentials not enabling protection, explorer freezes

Hello,

I'm not sure what is wrong but every time I boot win 7 home premium 64 bit now, Microsoft Security Essentials won't enable the real time protection (when I go to turn it on it gives me error code 0x800705b4), and everything in the task bar is becomes frozen. After about 10 -15 minutes (every time) windows explorer pops up and says its not working, restarts, and then everything works normally from there on out. Malwarebytes also fails to load until this time as well. When I boot in safe mode, I do not experience these problems, and when I check the event viewer it tells me there are Service Control Manager errors and MS Antimalware errors. I uninstalled and reinstalled MS Security Essentials, and even recovered the system to a previous time, but to no avail. How can I fix these issues at startup?

Thanks,

Brian

Hi guys, and thanks for responding.

I have already tried a full system scan with Malwarebytes a day ago (with the paid version and found nothing wrong), and prior to my initial posting I read how to do the sfc/scannow and /verifyonly utility. I ran them both twice and each time there said that there was nothing wrong and nothing to repair.

I'd be happy to try again and post the results for you when I get back home which should be around 6:30pm Mountain Time today.

I should probably also mention that everything was working fine until I tried to turn off MS Security Essentials from the Services list when I tried to install HP printer Drivers. I think I turned off security client user interface or something to that effect, but when I turned it back on that's when all the problems started.

I'd try uninstalling MSE and then reinstall.

As a general rule of thumb it's better to just turn off real-time protection rather than messing with services. (MSE dashboard > settings tab > real time protection)

I've actually done this twice but to no avail. Of course I figured out how to turn off MSE through the dashboard after I screwed everything up.

Hi Ryan,

I did everything you suggested in order and I am still getting the following issues:

- during re-installation of MSE windows explorer stopped working, clicked restart, and it began to work again.
- when I initially reboot, still I am getting the same problem, the wifi strength meter (the one that's part of the oem network and sharing app) stays frozen with the little blue circle as if its thinking.
- when I right click on "open network and sharing center", a blank window opens and the mouse changes to the blue circle again for about 14 minutes until windows explorer crashes again, reboots, and then everything works fine thereafter
- Firefox freezes, but does not show that it is not responding both in upper right part of the app itself, as well in the task manager.
- again all of the problems seem to resolve themselves after about 14-15 minutes after booting, but manifest every time for those first 14-15 after I restart the computer.

The problem was occuring without MSE installed as well...

Ok..........so I probably should have mentioned this before, but I now think the problem was just the crappy HP printer driver for Win 7 I installed to begin with.

I uninstalled several HP programs (all for the printer) and now the problems seem to be resolved. The only issue now seem to be trying to get rid of ALL the crappy HP files it installed when I tried to set up the printer and make it work wirelessly over the home network. I should have known but didn't suspect it because the printer was working.

Thank you to everyone that tried to help. I feel pretty dumb now. I'm going to search for ways to get rid of the rest of this HP crap now...
