Your logfile shows signs of malware, and not just the file that AVG was detecting. Among other things, your logfile shows that you have Weatherbug.
Weatherbug is a utility that shows current weather conditions and future weather forecasts for your locale. It is an adware supported product, which contains both banner and pop-up ads. It is often installed as a secondary application with many popular pieces of software. If you're looking for a free alternative that doesn't display ads, you may want to try WeatherPulse

I recommend you uninstall it. If you wish to do so, please click on Start -> Control Panel -> Add or Remove Programs. If Weatherbug appears, click on it and click Remove.

* Download Dr.Web CureIt to the desktop:
ftp://ftp.drweb.com/pub/drweb/cureit/drweb-cureit.exe

• Doubleclick the drweb-cureit.exe file and Allow to run the express scan
• This will scan the files currently running in memory and when something is found, click the yes button when it asks you if you want to cure it. This is only a short scan.
• Once the short scan has finished, Click Options > Change settings
• Choose the "Scan"-tab, remove the mark at "Heuristic analysis".
• Back at the main window, mark the drives that you want to scan.
• Select all drives. A red dot shows which drives have been chosen.
• Click the green arrow at the right, and the scan will start.
• Click 'Yes to all' if it asks if you want to cure/move the file.
• When the scan has finished, look if you can click next icon next to the files found:
• If so, click it and then click the next icon right below and select Move incurable as you'll see in next image:
  
  This will move it to the %userprofile%\DoctorWeb\quarantaine-folder if it can't be cured. (this in case if we need samples)
• After selecting, in the Dr.Web CureIt menu on top, click file and choose save report list
• Save the report to your desktop. The report will be called DrWeb.csv
• Close Dr.Web Cureit.
• Reboot your computer!! Because it could be possible that files in use will be moved/deleted during reboot.
• After reboot, post the contents of the log from Dr.Web you saved previously in your next reply.
