Sorry- sometime a questions gets lost between the cracks:
Mbam has remove the Trojan Zlob infection. Have SAS remove the tracking Cookies. I'll help you reset Cookies to block these.
Looking at your HijackThis log, I see:
C:\PROGRA~1\Grisoft\AVGFRE~1\avgamsvr.exe
This appears to be the original AVG v1- way out of date, meaning you're not getting updates. For an antivirus program, not getting updates is as bad as having no AV at all!some earlier version-Most current is V8. You need to update that ASAP.
But I see AVG v7 loading here- still out of date:
O4 - HKUS\S-1-5-19\..\Run: [AVG7_Run] C:\PROGRA~1\Grisoft\AVGFRE~1\avgw.exe /RUNONCE (User 'LOCAL SERVICE')
O4 - HKUS\S-1-5-20\..\Run: [AVG7_Run] C:\PROGRA~1\Grisoft\AVGFRE~1\avgw.exe /RUNONCE (User 'NETWORK SERVICE')
O4 - HKUS\S-1-5-18\..\Run: [AVG7_Run] C:\PROGRA~1\Grisoft\AVGFRE~1\avgw.exe /RUNONCE (User 'SYSTEM')
O4 - HKUS\.DEFAULT\..\Run: [AVG7_Run] C:\PROGRA~1\Grisoft\AVGFRE~1\avgw.exe /RUNONCE (User 'Default user')
Otherwise, the log is clean. Please take care of updating the antivirus, have SAS remove the Tracking Cookies, then run HijachThis again and attach log.
