this is my first post, so I hope to comply with all the rules and to be in the right place. If not, I do apologise in advance for that.
Since a few weeks, my laptop has become very unstable. I get most of the problems when trying to start it: it hangs or I get a blue screen during booting or login. I have already run an extensive memory test, so I would tend to exclude a HW problem. When I manage to boot and login successfully, I get problems mostly with Internet Explorer (redirections after Google search, it hangs rather often).
My normal Antivirus (VirusScan Enterprise 8.0.0 by McAfee) detected (and declated to have removed) a few trojans but all problems described above were still there. I then installed Spybot, which found (and declated to have removed) the following:
Smitfraud-C.gp: [SBI $8E7F06B8] Ausführbare Datei (Datei, nothing done)
Win32.Agent.sd: [SBI $2968F182] Einstellungen (Registrierungsdatenbank-Schlüssel, nothing done)
Win32.Agent.sd: [SBI $72640A46] Programm-Verzeichnis (Verzeichnis, nothing done)
Win32.Agent.sd: [SBI $8DCCA8F7] Daten (Datei, nothing done)
But again, all problems above persist...
The log file of HijackThis is attached.
I'll be very grateful for any hint!
