hello, techspot gurus... i've had a couple of strange problems lately - both today, in fact. at this point, i haven't noticed any performance issues, but i'd like to know what's going on in there... first, i got an error message relating to "LSA Shell (Export Version)". after this error message, i was told i had 60 seconds before the computer would shut down - i was locked-in to this, with no visible way to abort the shutdown. this LSA Shell error has only occurred once (to my knowledge). searches related to the LSA Shell problem led to alot of old (2004-06) threads mostly dicussing varieties of the Sasser virus. i downloaded and ran McAfee's Stinger and Symantec's standalone "Sasser Fix" - neither one found anything amiss. i ran SS+D, but it also found nothing. i searched a little more, found some more old info, and then tried TrendMicro's House Call: this is where it gets weird... i successfully ran House Call, but it somehow failed in the final moments. House call had already showed me a few problems - none seeming severe - which it intended to remove. after i clicked on the remove button, it froze up and the program became unresponsive. i tried House Call again and received this message upon attempting to begin the connection: "An error occurred while trying to transfer data from the Internet! Do you want Trend Micro House Call to try resending the required files?" then IE became unresponsive and the message window was frozen (whether i chose "Yes", "No", or tried to exit IE by clicking the X, i couldn't get out). i eventually just CTRL-ALT-DEL-eted my way out. and i've done the same three subsequent times... i can't get House Call to work. i re-read the "8 simple steps" and had to download some new stuff due to changes since the last time i was here. i ran MalwareBytes and SuperAnti-Spyware. i'll post the MalwareBytes log, but the SAS search turned up nothing. also, here is my HJT log (made after I'd done all the other steps). so... those are my onle two symptoms - LSA Shell (Export Version) crashing the system once, and inability to run HouseCall. thanks for all you guys do.
