Windows XP here. On the first run through, I got a popup message about verifying a file right after a message about unzipping files. At the bottom of iexplorer 8, it was showing an attempt to access a Microsoft site. Nothing happened for 10 min so I cancelled the process. I ran update again a second time and it completed successfully with no popups or unzipping messages. As I often do, I always run update once more after completion to verify no other files are in need of update. Today, the malicious software app was updated a second time. The first time was also the July 2013 version and it said it completed successfully. After updating it a second time, there were no more updates shown on the third run of Windows Update. In all there were 14 updates to my system as I refused Bing Desktop 1.3.
