I have Windows 7 Home edition; Microsoft updates are problematic, have had to download individually to get important security updates installed, not all have installed, computer takes ages to create a Restore point and then does not always succeed in reconfiguring at reboot after install. Got error code 643, Have Norton 360, tried downloading the Norton Power Eraser but this failed, and got error code 0x80070005, n44, n66.


Can anyone help? Spent last two days trying to install MS security updates one by one and the last two simply will not install.

 Download and install Malwarebytes, get it up to date, and do a scan.  When the scan finishes, click Quarantine all.  After that boot to Safe Mode and do a full system scan with your antivirus.


 If you still have problems after that, do this.

Please download and run Speccy.  After running it click File -> Publish snapshot... Copy and paste the link it gives you into your next post.  Then download minitoolbox and run it with the following boxes checked:
List last 10 Event Viewer Errors
List Installed Programs
List Users, Partitions, and Memory size
List Minidump files
Copy the resulting log and paste into a reply here.
Good luck.

Everyone with a computer should back his system up to an external hard drive regularly.  :thumbsup:
