One of the latest security issues is a code executor. An update released by microsoft was downloaded and "installed". Every time I turn off my PC with Windows XP Home edition it tells me there is an update to install. The same update. It doesn't want to install.
Also my Norton spyware and scan software - free with BT Broadband line is not accepting spyware scans (saw that it said last run: never) and i have run both of them before.
Is there any connection with MS's update?
