Unless there are more issues, you needn't post more logs. You can also re-enable your Internet connection.
Just some cleaning up to do.
Now that your computer is clean, we no longer need to keep the removal tools downloaded. They will need to be removed.

Keep your system updated
Microsoft releases patches for Windows and Office products regularly to patch up Windows and Office products loopholes and fix any bugs found. Please ensure that you visit the following websites regularly or do update your system regularly.
Install the updates immediately if they are found. Reboot your computer if necessary, revisit Windows Update and Office update sites until there are no more updates to be installed.

Open up any Office program.
Go to Help > Check for Updates

If you are forgetful, you can change some settings so that you will be informed of updates. Here's how:
- Go to Start > Control Panel > Automatic Updates
- Select Automatic (recommended) radio button if you want the updates to be downloaded and installed without prompting you.
- Select Download updates for me, but let me chose when to install them radio button if you want the updates to be downloaded automatically but to be installed at another time.
- Select Notify me but don't automatically download or install them radio button if you want to be notified of the updates.
Besides Windows that needs regular updating, antivirus, anti-spyware and firewall programs update regularly too.
Please make sure that you update your antivirus, firewall and anti-spyware programs at least once a week.
Be careful when opening attachments and downloading files.
- Never open email attachments, not even if they are from someone you know. If you need to open them, scan them with your antivirus program before opening.
- Never open emails from unknown senders.
- Beware of emails that warn about viruses that are spreading, especially those from antivirus vendors. These email addresses can be easily spoofed. Check the antivirus vendor websites to be sure.
- Be careful of what you download. Only download files from known sources. Also, avoid cracked programs. If you need a particular program that costs too much for you, try finding free alternatives on Sourceforge or Pricelessware.
Surf safely
Many of the exploits are directed to users of Internet Explorer and Firefox.
Using Firefox with NoScript add-on helps to prevent most exploits from running as NoScript by default disables all scripts on all websites. If you trust the website, you can manually allow it.
If you prefer to use Internet Explorer, here are some settings to change to improve the security of Internet Explorer.
For Internet Explorer 7
Please read this article to configure Internet Explorer 7 properly.
Stop malicious scripts
Windows by default allow scripts (which is VBScript and JavaScript) to run and some of these scripts are malicious. Use Noscript by Symantec or Script Defender by AnalogX to handle these scripts.
Backup regularly
You never know when your PC will become unstable or become so infected that you can't recover it. Follow this Microsoft article to learn how to backup. Follow this article by Microsoft to restore your backups.
Alternatively, you can use 3rd-party programs to back up your data. One example can be found at Bleeping Computer.
Avoid P2P
P2P may be a great way to get lots of stuffs, but it is a great way to get infected as well. There's no way to tell if the file being shared is infected. Worse still, some worms spread via P2P networks, infecting you as well. If you do need to use them, use them sparingly. Check this list of clean and infected P2P programs if you need to use one.
