No worries, you're not bogging anything down. Most users don't give enough info...when it comes to malware, "too much" info can be a good thing. To answer your first question...the Windows Recovery Console was added by ComboFix. You'll have to get used to seeing a new bootup, but trust me, this is something you should have. If you ever have any major problems, this option could very well save your computer. And don't worry, your computer is still booting in the normal mode.
As for AVG, uninstalling and reinstalling is probably a good idea. If it doesn't work, then you can get more help on their forums. The latest version of AVG has all sorts of quirks and difficulties, and they know a lot more about making it work than I do.
By looking at your latest log, it looks like your infection should be gone now. At the very least, it's inactive. If you happen to come across any traces of it, just let me know and I can help you remove them.
You no longer need ComboFix, so let's go ahead and uninstall it. Click on the Start menu and go to Run. Type in
combofix /u (note the space before "/u") and click OK. It will now be removed.
You should now clean out your System Restore. This is to remove any infected files that have been backed up by Windows. Please follow these steps...
1. Go to Start > Programs > Accessories > System Tools > System Restore
2. Click on System Restore Settings.
3. Check
Turn off System Restore and click OK.
4. Restart your computer.
5. Follow steps 1 and 2 to return to the settings,
uncheck Turn off System Restore, and click OK.
6. Create a new restore point and close the program.
System Restore will now be active again. If you would like to learn more about System Restore, go
