ZA me pitao da li da blokira program Isass.exe

dolje je bio opis sta je to LSA Shell.

prije sam uvek rekla 'deny' ,
ali danas sam htela znati sta je to..
i Kao obicno kad pitam Google dobijem masu mogucih odgovora ...procitala sam da nije opasan..
i propustila sam ga samo da se rijesim prozorcica -opomene..

ali kad sam dalje citala onda je ispalo da moze biti 'worm' sasser..
uh, bas sam pozalila sto nisam odmah pitala vas.

onda sam nasla kako se ispise log file ..sa hijackthis.exe..
(a tu ste me vi zbunili u nekom topicu ..da li je bezopasno koristiti taj program.. je ali ipak sam to uradila..

pa evo , molim 'doktore' za dijagnozu Smile

i recite mi molim vas ,da znam vec jednom,

Ne vidim ništa maliciozno u logu koji si postavila.

Napravila si grešku u pisanju:
lsass.exe (početno L) je legitiman Windows-ov fajl. [on je izlistan u tvom logu kao proces]
Isass.exe (početno I kako si ti napisala) bi bio trojan/backdoor.

Citat:sta da radim s tim lsass.exe kad me ZA pita?
Možeš ovo kao i do sada ako nemaš neke smetnje a možeš i da ga pustiš out Smile
