Pokud je ctfmon.exe v system32, tak je vše v pořádku, je to důležitý systémový proces a z tohoto umístění jen rozhodně nedoporučuju mazat.

V logu nic špatnýho není. Chybí ovšem firewall, ten ve Windows nestačí.

Zkus teda CF:

Stáhněte a uložte na plochu ComboFix: http://download.bleepingcomputer.com/sUBs/ComboFix.exe

spusťte aplikaci pod účtem s administrátorským oprávněním - následuje licenční ujednání, stiskněte klávesu 1 pro pokračování - začne se testovat (celá akce trvá cca. 5-10 minut, někdy i trochu déle) - během skenu se nepokoušejte spouštět žádne jiné aplikace a neklikejte do okna ComboFixu - po dokončení se automaticky otevře okno poznámkového bloku s textem (pokud se tak nestane, log je v C:\ComboFix.txt), který sem pomocí známých klávesových zkratek Ctrl + A (označení celého textu) -> Ctrl + C (uložení do jakési schránky) -> Ctrl + V (vložení textu) zkopírujte - a počkejte na další postup

diky za pomoc uz sem ten smejd samzal bylo to trochu slozity ale nejak nahodne se mi to povedlo jinak diky za pomoc jen jakej firewall byste doporucili aby byl jednoduchej na obsluhu a aby nedal paseku s hrama po LAN a netu? proste musi bejt co nejvic userfree a freeware

No být tebou tak bych ten log z ComboFixu se dal, protože toho worma co jsi tam měl tak se šíří po výměnných médií.

já žil v dojmu že ctfmon.exe je legitimní součást windows, a normálně vypnout nejde, tohle je nějaká věc co se maskuje pod stejným názvem?

jo jeste jedno CTFMON.EXE je v system32.. a pak je jeste dalsi pod stejnym nazvem a to je vir!
