    Like the title says, lsaass.exe crashes randomly every few hours. I don't know what it could be. I don't think I can do anything to make it happen. It just happens by itself. I'm stumped on this one, so I'm asking for your help. I've got two crash reports for you.

    It seems this could be an imitation of a genuine Microsoft essential file lsass.exe and fake copies of that file are frequent malware attacks because it can be disguised with an upper case I for India to imitate the lower case l for Lima that is the proper letter.

    Go to http://www.trendmicro.com and download HijackThis, install as directed and click to Scan and Save a Log. Do nothing else at this stage than to post that log back here and one of the advisers with Blue or Gold shields beside their name will advise what to do next.

    Since I last posted, I uploaded the file lsaass.exe to Kaspersky for analysis. It was a trojan. So I deleted it and removed some references to it with Autoruns. Now I'll reboot, do a complete virus scan, and see if there's any trouble left.

    I have NOT analysed your HiJack for infections.
    I am NOT authorised to do so.
    As Saga Lout mentioned that must be done by an authorised person.

    In relation to more general matters
    Is that Malwarebytes the free version, if so, that does not provide real time protection.
    I realise Spybot search and destroy is installed but I may be mistaken but I cannot see an anti-virus

    As you say, Mac, we couldn't psosibly comment :D but I can't help noticing traces of a fomer XP installation in there. Despite Captain Siberia finding and removing a Trojan, I think there is work to be done on this one.

    Yes, there was a former XP installation. I got a new computer with a new motherboard, so I had to reinstall the operating system. It's running perfectly fine for me, unless you think I should do some extra things.

    The virus is gone. I got rid of it.

    I actually haven't relied on real-time protection as much for certain reasons. One, it slows things down. Two, it catches too many false positives. It deletes programs that I want, like the FFMpeg front-end. Three, I've had anti-virus software with real-time protection, and sometimes I just plain get viruses anyway. Four, when I get a virus, it tends to take scans to get rid of it, rather than real-time protection. Five, I know where viruses come from, so I make it a policy not to mess around with files that reek of virus.

    It is your computer and your decision.
    But your system did not work too well on this occasion.

    I hope so but every customer who comes through my door says their computer have a virus yet of all the systems I fix, I haven't seen a virus since I don't know when. I do deal with a lot of fake AVs and HDD tools, Trojans and Rootkits that go to the heart of the system and the most dangerous are those which just quietly sit there and get on with robbing you of data without doing anything to make their presence felt.

    I genuinely hope you got everything out but I think despite your dislike of protection, you would benefit form paying to upgrade MBAM from the fre version to a lifetime subscription for a very small cost. It isn't invasive or intrusive and it will keep nasty stuff at bay. Also, something I never thought I would hear myself saying - Microsoft has a valuable AV utility - it's called Microsoft Security Essentials and it too works quietly in the background.

    As Macboatmasters says, it's your choice.

    The filename in question lsaass.exe is definitely not the same as the normal System file lsass.exe, so it would most likely been a trojan.

    Simple deletion often does work for Trojan infections, but of course, not always. More in-depth scanning is advised but if you are happy, we are happy.

    The scan results you posted clearly show the filename as lsaas, so I do not think it is a typo that you made. And, the normal lsass.exe file shows in your HJT log......

    If you wish the thread Closed just let us know. You can also mark your own thread "Solved" if you think it's done........

    Yeah, the virus scanner tools can't find any trace of it anymore. Looks like we're clean.
