Hi, I am having reoccurring memory exceptions in smss.exe usually the same memory location. Task Manager shows 2 smss.exe processes running one is using 2,624K and the other is using 392K of memory. I have located three copies of the files one in c:/windows/system32/ 50K in size and one in c:/windows/i386/system32/ 459K in size (this one is all capital letters), and a smss.exe-002D997.pf in the Prefetch subdirectry and a SMSS.EX_ in C:/i386/ I have a similar system without problems and it shows the two files at the same size. But there is only one instance of the program running. The system has 3 problems that I have noticed The reoccurring application error in smss.exe instruction at 0x7c901010 referring memory at 0x00875a4 in a message window. The location is usually the same one. This opens a dialog for visual studio asking if I want to debug it, I generally click NO but if yes the debugger opens and hangs. after closing the exception message, sometimes several times, the the user settings will load. The wireless network may or may not load. It can also cause other problems intermittently, such as the task bar not displaying there are also occassional other program exception errors I tried to boot in safe mode, all three types and drivers would load and then it would go back to the safe mode selection screen, but I can select boot from windows normally and it will boot up windows. I have the paid version of AVG internet security but the command center will not load, the outline of the program shows then it hangs, I tried to reinstall it and it failed with a program exception error. win32 exception in avgxxxxx.exe install - I do see the avg processes running in task manager I tried running housecall both with java and a local kernel but it hangs in the idle mode while on the setup and download screen. I can not run AVG anti virus Search and destroy found 2 viruses smithfraud and Virtumone and on a second run through showed clean. There are about 20 Microsoft.windows.redirectedHosts. [xx] These do not show up on my similar machine in Search and Destroy I ran CCleaner and deleted the recommend files I ran Ad-Aware smart scan and it found 1 critical problem - Zedo and deleted it. ran a deep scan and found virtumode deleted it Before I did something really stupid out of frustration I figured I better ask the experts.
