Hello Ghot,
Welcome to IANAG!
Your log is essentially clean. Can I ask in the future, if you feel you need to post a log that you NOT post a parsing of the log, just the log itself.
Those of us here who read logs do our own parsing, using various programs. Posting the parse will just confuse others not familiar with the procedure of reading the logs. Most of us here read and check them line by line.
Now the two lines you are concerned with;
O20 - Winlogon Notify: NavLogon - C:\WINDOWS\system32\NavLogon.dll
O20 - Winlogon Notify: WgaLogon - C:\WINDOWS\SYSTEM32\WgaLogon.dll
are perfectly legitimate lines.

The first one refers to your Norton Anti-virus program and the second one refers to the Windows Genuine Advantage tool.

You have one line I would recommend fixing by running HJT again and placing a checkmark next to it, then click the FIX button and exit HJT;
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Local Page =

You are also running a program which I have never seen before which is SnoopFree Privacy Shield. Now this appears to be a legitimate program but the one we always recommend is SpywareBlaster which DOES
Prevent the installation of ActiveX-based spyware, adware, browser hijackers, dialers, and other potentially unwanted software.
Block spyware/tracking cookies in Internet Explorer and Mozilla/Firefox.
Restrict the actions of potentially unwanted sites in Internet Explorer.
This is an EXCELLENT program. It is FREE and best of all, it DOES NOT run in the background all the time. Keep it updated and that is it. And believe me IT DOES WORK.
