I attempted to check for updates but it never completed. I had it running for almost 2 hours and it never completed the update check. In the bottom right-hand corner, I have the Windows Update icon there and, when I hover over it with my mouse, it shows Windows Update is 8% complete. So it IS downloading the updates but it's VERY slow. It's been at least 8 hours and it's only gone up to 8%, so there's obviously an issue. I can show you what I have in my WU.log as it is right now if you'd like.
Edited to Add: After starting up my computer this morning, I found that the Windows Update is now up to 40% complete. I also tried to update MSE and I got a message stating that MSE couldn't update the definitions due to an internet or connectivity issue. Which is strange because obviously I can go online and I have no other network issues.
MSE should install it's definitions first, before
any updates install. It's difficult to assess what the issue is without first seeing the WindowsUpdate.log. However, it's quite obvious that
something ain't right.
1. Is a 3rd party firewall being used ?
2. Was another antivirus/security suite installed before MSE was ?
You can either wait for this month's round of massive updates to install or you can open the
Windows Update Troubleshooter ( it's under System and Security ) and see if it can speed things up some.
To be perfectly honest here, I've not seen the specific return code, 80010108, before in 10 years of helping folks out with Windows Update issues. I'm leaning towards either a malware/network connectivity issue, or a
combination of known troublesome updates ( .NET Frameworks or Visual C++ ) as being the cause.
Can you manually download,
save, and then install the latest definitions for MSE ?
Either click this link to obtain them -
Microsoft Security Essentials 64-bit, June 24, 2011 or, go to the
Microsoft Malware Protection Center and click the 64-bit link next to Microsoft Security Essentials, 64-bit.
Save
mpam-fex64.exe, do
not run it with the browser open.
When the download completes close the browser and
all other open program or applications.
Right click mpam-fex64.exe and choose 'Run as administrator', then agree to the UAC prompt to install the defs.
If the system is still installing updates then suggest you restart it to Safe Mode for now -
How to Start Windows 7 in Safe Mode
All of the previously downloaded updates will resume their installation
after you've done a system scan from within Safe Mode and the system is restarted to normal Windows mode.
Please let us know about your results from using the Windows Update Troubleshooter, in updating MSE, and the results of the MSE scan from Safe Mode, along with the answer to the 2 questions.
