Ciao, da ieri improvvisamente il mio pc si è preso un virus. Avast me lo segnala come Win32:Malware-gen. In pratica, anche se elimino il file, dopo un tot di tempo (3-4minuti) si genera in maniera automatica un altro file dello stesso tipo...esempio:
C:/Windows/Temp/uoqp.tmp/svchost.exe
C:/Windows/Temp/fghui.tmp/svchost.exe
C:/Windows/Temp/augvi.tmp/svchost.exe
etc...
Prima di postare sul forum ho fatto eseguire la scansione di avast all'avvio del sistema ma non mi trova nulla...ho eseguito una scansione con spybot S&D e con Malwarebytes' Anti-Malware (come consigliato da topic in rilievo) entrambi mi hanno rilevato due infezioni diverse...le ho rimosse, riavviato, riscansionato e nessun problema rilevato dagli anti malware...avast mi rileva comunque il virus....c'è un sistema per capire che file mi genera sti svchost.exe "fasulli"? Vi allego in ogni caso il log di HijackThis
Nel caso vi servano maggiori informazioni basta dirlo...speriamo benecodice:Logfile of Trend Micro HijackThis v2.0.2 Scan saved at 22:22:41, on 04/03/2010 Platform: Unknown Windows (WinNT 6.01.3504) MSIE: Internet Explorer v8.00 (8.00.7600.16385) Boot mode: Normal Running processes: C:\Windows\system32\Dwm.exe C:\Windows\Explorer.EXE C:\Programmi\Avast4\ashDisp.exe C:\Windows\System32\Ctxfihlp.exe C:\Programmi\Creative\Volume Panel\VolPanlu.exe C:\Program Files\Java\jre6\bin\jusched.exe C:\Program Files\HP\HP Software Update\hpwuschd2.exe C:\Program Files\Windows Live\Messenger\msnmsgr.exe C:\Program Files\Windows Sidebar\sidebar.exe C:\Programmi\NetGear\WG111v2.exe C:\Windows\system32\taskhost.exe C:\Windows\SYSTEM32\CTXFISPI.EXE C:\Programmi\Firefox\firefox.exe C:\Program Files\Trend Micro\HijackThis\HijackThis.exe R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://go.microsoft.com/fwlink/?LinkId=69157 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://go.microsoft.com/fwlink/?LinkId=69157 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = http://go.microsoft.com/fwlink/?LinkId=54896 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = http://go.microsoft.com/fwlink/?LinkId=69157 R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant = R0 - HKLM\Software\Microsoft\Internet Explorer\Search,CustomizeSearch = R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyOverride = local R0 - HKCU\Software\Microsoft\Internet Explorer\Toolbar,LinksFolderName = O2 - BHO: HP Print Enhancer - {0347C33E-8762-4905-BF09-768834316C61} - C:\Program Files\HP\Digital Imaging\Smart Web Printing\hpswp_printenhancer.dll O2 - BHO: AcroIEHelperStub - {18DF081C-E8AD-4283-A596-FA578C2EBDC3} - C:\Program Files\Common Files\Adobe\Acrobat\ActiveX\AcroIEHelperShim.dll O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file) O2 - BHO: Guida per l'accesso a Windows Live - {9030D464-4C02-4ABF-8ECC-5164760863C6} - C:\Program Files\Common Files\Microsoft Shared\Windows Live\WindowsLiveLogin.dll O2 - BHO: Java(tm) Plug-In 2 SSV Helper - {DBC80044-A445-435b-BC74-9C25C1C588A9} - C:\Program Files\Java\jre6\bin\jp2ssv.dll O2 - BHO: HP Smart BHO Class - {FFFFFFFF-CF4E-4F2B-BDC2-0E72E116A856} - C:\Program Files\HP\Digital Imaging\Smart Web Printing\hpswp_BHO.dll O4 - HKLM\..\Run: [avast!] "C:\Programmi\Avast4\ashDisp.exe" O4 - HKLM\..\Run: [CTxfiHlp] CTXFIHLP.EXE O4 - HKLM\..\Run: [VolPanel] "C:\Programmi\Creative\Volume Panel\VolPanlu.exe" /r O4 - HKLM\..\Run: [SunJavaUpdateSched] "C:\Program Files\Java\jre6\bin\jusched.exe" O4 - HKLM\..\Run: [HP Software Update] C:\Program Files\HP\HP Software Update\HPWuSchd2.exe O4 - HKCU\..\Run: [msnmsgr] "C:\Program Files\Windows Live\Messenger\msnmsgr.exe" /background O4 - HKCU\..\Run: [Sidebar] C:\Program Files\Windows Sidebar\sidebar.exe /autoRun O4 - HKUS\S-1-5-19\..\Run: [Sidebar] %ProgramFiles%\Windows Sidebar\Sidebar.exe /autoRun (User 'SERVIZIO LOCALE') O4 - HKUS\S-1-5-19\..\RunOnce: [mctadmin] C:\Windows\System32\mctadmin.exe (User 'SERVIZIO LOCALE') O4 - HKUS\S-1-5-20\..\Run: [Sidebar] %ProgramFiles%\Windows Sidebar\Sidebar.exe /autoRun (User 'SERVIZIO DI RETE') O4 - HKUS\S-1-5-20\..\RunOnce: [mctadmin] C:\Windows\System32\mctadmin.exe (User 'SERVIZIO DI RETE') O4 - Global Startup: NETGEAR WG111v2 Smart Wizard.lnk = ?
