Not much too wrong with your log
Have you cleaned out your temp folder
This is a great little utility to aid with it called
Windows Cleanup!After you have it installed
Simply open it, Select Cleanup
Restart your computer afterwards
This will also remove your cookies, if you prefer not to remove them and manually add
signins and passwords later---Open the options and uncheck cookies
This won't remove them forever, just till the next time you sign in
I would recommend the Standard Cleanup for troubleshooting purposes
I do notice this in your log
O4 - HKLM\..\RunServices: [ScriptBlocking] "C:\Program Files\Common Files\Symantec Shared\Script Blocking\SBServ.exe" -reg
This tells me you may have Norton's installed or not completely uninstalled
Their site has complete removal instructions
Having more than one AV on Startup can cause slower bootup times and conflicts
Optionally, you can have hijackthis fix this entry
O4 - HKLM\..\Run: [QuickTime Task] "C:\WINDOWS\SYSTEM\QTTASK.EXE" -atboottime
Fix checked only when ALL other windows are closed, including this one
and then Restart
Can you let me know where these popups are directed from
Some kind of name even...
If your not running a popup blocker, you may consider installing the
Free Google ToolbarIf you don't have your own popup blocker
Post back with a fresh hijackthis log after you have done the above, and let me know
some info on the popups
Don't fix anything with hijackthis after you have done the above, let me see the whole log
