Hi,
Can you also post a new HijackThislog please?
Concerning your Security center complaining about your Antivirus, make sure it's up to date (Your AVG).
Also, I recommend you install a desktop Firewall instead of using the Windows Firewall, because the Windows Firewall is not powerful enough.
Take a look at this link for the firewalls I recommend: http://users.telenet.be/bluepatchy/m...html#Firewalls
You were dealing with A LOT of infections including backdoors - for which you feared.
That's why I suggest you change all your passwords.
Also, I am a bit disappointed that you already had AVG Antivirus installed and it actually didn't find/removed that much, because when I look at the Combofix log - it still deleted a LOT of malware afterwards.
There's still another thing I would like to check though.;
Download and Save blacklight to your desktop.
F-Secure Blacklight: https://europe.f-secure.com/blacklight/try.shtml
(fsbl.exe - graphical user interface)
Double-click fsbl.exe then accept the agreement.
click > scan then > next,
You'll see a list of all items found - if found, so don't worry it tells that there were no files found.
In case hidden files were found, Don't choose for rename yet! I want to see the log first, because legit items can also be present there...
There must be also a log on your desktop with the name fsbl.xxxxxxx.log (the xxxxxxx stand for numbers)
Post the contents of the log in your next reply as well...
