Your log is fairly clean.
Re. your first post it seems AVG was doing its job. Whatever it found was removed and not on your machine any more (unless it's hiding deeper than HJT can see which is always a possibility).
Do you know what this fie is, what it does and which program installed it ....
C:\WINDOWS\
CameraFixer.exe?
Please advise.
Which firewall are you using? I can't see one in the log.
The version of HJT you are using is slightly out of date. Merijn has now sold the program to Trend Micro and the most recent version is available here ....
http://www.trendsecure.com/portal/en-US/threat_analytics/HJTInstall.exe- Save HJTInstall.exe to your desktop.
- Doubleclick on the HJTInstall.exe icon on your desktop.
Please use this one in the future.
Your HJT file is on a temporary place on your computer. The program makes backups which could easily be lost if HJT isn't somewhere more permanent.
Go to the file ...
C:\Documents and Settings\Administrator\Local Settings\Temporary Internet Files\Content.IE5\QVQJDR8X\
HijackThis[1].exe....and drag & drop it directly on to your main hard drive.
All those 018 entires are form Logitech Desktop Messenger. It clogs up the machine. Best advice is to remove / uninstall that program and fix all this 018 entries with HJT thus ...
Turn off Windows Defender and Spybot's TeaTimer application as they could hinder HJT's fixing process.
Open HJT ... click on 'Do a System Scan Only'... put tick/check marks next to this entry IF it's still present ....
O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)AND all those 018 entries IF still present.
Remember to close ALL open browser windows – including this one – before clicking on “Fix Checked” at the foot of the HijackThis window.
When this is all done re-activate Defender and Spybot's resident TeaTimer protection.
Post a fresh HJT log
with an update on how the computer is behaving now.
