Hi RejZoR,

  • this is a new PC ? is a hardware problem possible ?

  • you have done scandisk /intensive & a RAM-Test ?

  • did you change all your Passwords… ?

  • can you run an Onlinescan, e.g. by Trend and/or RAV ?

  • are Ports 135, 139, 445, 4500 definetly blocked inbound ?

  • Please post a hijackthis_log: http://hjt.klaffke.de/en

  • if Lsass is corrupted, this might tell/fix it:
    start → run → SFC /scannow (System file check will start & replace “bad files”)

P.S.: Avast Cleaner results imho don’t tell much here, as this could also be some AgoBot/PhatBot-Variant (some 500 variants and counting…) :wink:
