Windows Live mail

[Cassel]

Tonight, when I came home from work I noticed a popup window saying something like Adware had been deactivated or something like that. I closed the window, thinking I would just restart it manually, but I guess I didn't pay enough attention to know exactly WHAT needed to be restarted. I also noticed that the Windows protection was in the process of scanning, something that is not supposed to be done during the day as it is scheduled for the night. I cancelled it as I figured it would just hog resources while I worked.

I also noticed that my computer was sluggish, and that darn new Internet Explorer 10 kept showing that 'the page X is not responding" (I hate that version of IE). As I tried to recover some of the pages that were not responding, I chose to close all the tabs, and completely close IE to restart. It didn't want to, and I had to repeat clicking on the X several times to finally get it to close.

Since it was closed, I thought of just restarting IE but it would not. I tried with the shortcut, with the Start menu, it would not start at all. I checked in the Task manager, and there were about 6 or 7 instances of iexplorer in the processes list. I was able to end all but two of them. Being unable to close the two left, I thought I would just restart the computer.

I went through the Start button to restart, and then my cursor didn't respond when I was asked if I wanted to force closing the programs left. I used the keyboard to answer the questions, but I kept getting other pages, like "logging out", "switching user", etc. I guess I didn't succeed with the keyboard.

I tried to get to the task manager, but again, my cursor was not responding, and using the keyboard didn't yield the result I wanted.

I chose to turn off the computer with the off button (last resort). When it restarted, I got a popup about my Dropbox being unable to access the windows registry (I am translating here as it was in French). Finally tried to open Winows Live Mail, and I get a popup saying "Windows Live Mail could not start. It may not be installed correctly. Make sure that your dis is not full or that you are not out of memory (0x80041161)". (and my disk still has 180GB free!)

Well, WLM was working fine before I turned it off so where is the problem and how do I solve that?
