Problema con cpu

[puccio]

Salve a tutti. Ho un problema con la cpu del mio windows xp. Infatti ogni volta che apro il task manager mi segnala che uso il 100% della cpu e quando vado a vedere qual è il processo che mi occupa quasi tutta la cpu mi segnala il seguente: jpjak.exe. Inoltre nn riesco a collegarmi ad alcuni link o addirittura nn riesco ad aprire il programma per cercare file o cartelle di windows

Questo comunque è il logfile di hijackthis relativo al mio pc

Rifai la scansione con Hijackthis, seleziona queste voci e premi Fix Checked:
O2 - BHO: (no name) - {2a6af021-17a2-4014-8624-cf6015f82fad} - C:\WINDOWS\System32\wdaa.dll
O4 - HKLM\..\Run: [rwnh1.exe] C:\WINDOWS\Temp\rwnh1.exe
O4 - Startup: jpjak.exe

Ora apri il Task Manager e termina il processo jpjak.exe.
Adesso scarica il programma Unlocker e con il suo aiuto elimina questi file in rosso:
C:\WINDOWS\Temp\rwnh1.exe
C:\Documents and Settings\americosa\Menu Avvio\Programmi\Esecuzione automatica\jpjak.exe
C:\WINDOWS\System32\wdaa.dll

Faresti bene a mettere un buon firewall per prevenire le infezioni, perché a quanto pare la suite di McAfee non è granchè, ed anche un buon antispyware come A-squared per fare la scansione ogni tanto. Ma la cosa più importante è il SP2, serve per tappare i numerosi buchi di Windows.

allarme linkoptimizer

credo che almeno per ora ci sia ben poco da fare... credo tu abbia la nuova variante e non ti dovrebbe permettere di usare i vari tool di rimozione... dai un'occhiata alla discussione relativa in rilievo, una delle prime del forum

Prova con il tools della norton dalla modalità provvisoria

I tools l'unica cosa buona della norton....questa mattina me ne ha rimosso uno di link optimizer.
