Ciao, svchost.exe in C:\windows\system32 è un legittimo file di sistema: non toccarlo. File con nome simile a quello sono sempre sospetti. Se vuoi puoi controllarli su http://www.virustotal.com o mandarli a Suspectfile per l´analisi.

Apri Hijackthis, premi do a system scan only. Poi chiudi tutte le altre applicazioni e le finistre aperte. Metti un segno di spunta accanto a queste voci e poi premi Fix checked

O2 - BHO: edit_html Class - {14D1A72D-8705-11D8-B120-0040F46CB696} - C:\Documents and Settings\ser\Desktop\929212843.dll

O3 - Toolbar: VisuExplorer - {92E1B3F7-0546-421E-9835-904D25B7BA66} - C:\WINDOWS\system32\msiev32.dll

Poi sempre da HijackThis, premi Open the misc tools section>>Delete a file on reboot. Nella casella che si incolla quanto ti scrivo sotto:
C:\Documents and Settings\ser\Desktop\929212843.dll

Premi Invio, ma non non accetatre di riavviare adesso. Ripeti la procedura due volte, inserendo di seguito
C:\WINDOWS\system32\winvbie.dll
e poi
C:\WINDOWS\system32\msiev32.dll

Dopo questo inserimento riavvia il PC. Al termine posta un nuovo log di HijackThis

OK, adesso mi sembra a posto

Attiva il firewall di XP o acora meglio, installane uno free, come Kerio, Zone Alarm o Outpost, ti serve per proteggerti dagli attacchi via internet.
