isass.exe, should i delete and how

[Ted2]

hi there
i've found isass.exe in my running processes, not sure what to do with it.

the computer performance wise..  is running slow. but it is a old computer handed down to me. and my knowledge of computers is not great - so i'm not sure how fast it should be runing anyway.. i'll only be using it for web browsing. so my only concern is that it is secure for me to use.  but any help would be appreciated

my computer:
windows xp home edition
1.80GHz  224MB ram

running ZoneAlarm and AVG free edition, up to date (nothing bad detected so far)

thank you for your time

**edit**
not sure it's called Isass.exe or Lsass.exe, hard to tell

[Broni]

not sure it's called Isass.exe or Lsass.exe, hard to tell

This is very important, because isass.exe is OPTIX PRO trojan, while lsass.exe is legit Windows file.
We'll sort it out.

You used outdated HJT version, so let's do it again...

Print these instructions out.

1. Download SUPERAntiSpyware Free for Home Users:

    * Click the "Close" button to leave the control center screen.
    * Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
    * On the left, make sure you check C:\Fixed Drive.
    * On the right, under "Complete Scan", choose Perform Complete Scan.
    * Click "Next" to start the scan. Please be patient while it scans your computer.
    * After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".

thanks broni
have not gone through those steps yet, have been a bit busy

but i just came back becuase i had an idea to use my web browser and search the word 'Lsass.exe' on this page

and Lsass apears in my HJT log
so i'm guessing it's all legit and fine like you say

although i don't understand HJT logs, so i was just wondering if there was anything there that shouldn't be there
the computer is new to me like i say.
but it used(before i reformated) to have a lot of problems and was infected with a virus or two.
i'm guessing all is fine now?

sorry for sounding a bit like a time waster. it's just this computer is on a network with anouther so was just wondering if this one was still had it's virus.
if someone doesn't mind giving my HJT log a quick look over that would be good, if not no prob.

P.S. are the logs just a matter of copying and pasting each part into a search engine? or is there more to it? i understand the running processes part, but not the rest of it. would be better if could do it..

thanks

I can't comment, or advice, unless I see those three logs.

Hi there, I wish everyone a happy new year.

I am experiencing something rather very strange, and I was wondering if anyone can help me.  I really do not know what to do.  I have windows XP.  and I am experiencing the virus (virus.win32.xorer.ee) which has three files which are critical.  (Isass.exe) + (smss.exe) + (ckvol.dll).  I can not install or run any anti-virus programs. My PC wont let me.  I can not run in safe mode.  I can not delete those items. so basically, this thing is in total control of my PC.  So please. if anyone can help me here i would really aperciate it.  Thank you.
