I've uninstalled AVG 2011 in favour of Microsoft Security Essentials. After rebooting & trying Windows Update, it gave me error code 80072EE2. Another weird thing I am experiencing is when typing single and double quotes, instantly two of them appear where I normally had to hit a space to have one of them show. Any thoughts? Thanks, Nick.

Weird; this all happened after switching AV's. Microsoft now detected PWS:Win32/Zbot.gen!AF as well in a running process, but after a full scan can't find the source that injects it.
