That trojan is the spoof vulnerability that IE can be affected with....if someone makes a specially crafted internet shortcut (url) that when you click it you think you are going to say...windowsupdate.com but really it takes you to installavirus.net and displays a fake windowsupdate.com webpage.
No you were not affected by that trojan...mcaffee flagged it because the page you viewed...that person was affected as it showed in the hijack log...I answered it and got the same warning.
If those links in the log were clickable and you clicked the link in the log to go to that site....then you could be affected.
Since all the webpages you view are stored in the temporary internet files folder for faster loading next time you view that page...McAfee will warn you about it.
You did right by letting McAfee delete it.
Windows has had a recent update to protect you from that problem.
Make sure you have all your windows updates, antivirus updates, and running a firewall.
