After upgrading from IE 10 to IE 11. I am fairly sure (not toally positive) this was the cause.
I am running an HP PAvilion with WIn7 Home Premeium 64bit
Several months ago I had a malware infiection mostlikely through a drive by download of a program called Sendori. I was able to sucessfully remove the infection. During that time I turned off my Auto-install of Windows updates and did them manually. I held off installing IE11 for a bit.
For a time I forgot I had shut off the Windows auto-install. About a week ago the prompt reminded me of updates. I installed all the major updates except for IE 11 and a coupld of .NET framwork updates as I did not want to overwhelm my system., tThe installs did create Restore points.
Once I got the other updates installed I let IE 11 and the .NET framework update install. Once my computer rebooted I tried to open up IE 11. It tried to go to my home page but IE said the page could not be displayed. And it was my normal homepage. Somewhat unsusal. I then tried to update MBAM 's databases. MBAM said it could not connect. I then noticed that Norton Internet Security had a red check in it. I opened MIS and tried to manually perform an update. Same thing as MBAM --- could not connect. I tried t6o update my older version of AdAware and was it able to update. I then opened SpyBot S&D (V1.6.2) and it was able to update.
I opened my local area connection status window and noticed that there was little activity BUT it showed (what I asume was) a goodly number of received bytes.
I then performed a System Restore to the last known good update I did a few days before. Once the machine rebooted everything seemed normal. I could update NIS and MBAM and access the internet through IE 10. I assumed that the restore worked. I have done restore before I thought I did everything correctly.
MBAM (I have the paid version) prompted me to update to the latest version 188.8.131.522. I let that download and install and MBAM said it needed to reboot the machine to install fully. Without thinking I let the machine reboot (not remembering the >NET Framework and IE 11 updates).
After reboot the same thing happened as described above. IE 11 could not access even my home page and MBAM could not update. I did another system restore to the know good point. Again I thought I did everything correctly.
After the reboot I still had IE 11 installed and partial internet connetion. I again openned up the Local connection and found bytes received was moving. I opened up Windows update and found 2 or 3 new IE 11 updates. Now Norton popped up with an error and MBAM still said it could not update. I went back to theSystem Restore and discovered all of my restore points were gone.
At this point I am at a loss to under stand what happened. I m writing this on my Daughters OLD laptop (Win XP mostly updated) with intermitant connection (I may hook it up to my cable modem but then again I may need my PC to be connected to I can run various things).
I have in the past let Windows install IE .NET updates with no problems.
Any help or insight would be appreciated. Please NOTE that I may seem to be unresponsive at time but this is because of my work schedule (I work second shift and the laptop may not be available for a day or so.
