Application error on most executables after startup
Posted on 2008-06-20
After removing a spyware, on startup I get multiple error messages like:
Application Error: The instruction at "....." referenced memory at "....". The memory could not be "read".
This happens on most executables, including explorer.exe, msconfig.exe, sfc.exe... here is a list of some executables, with the instruction address and the memory address:
verclsid 0x0040a54b 0x000a6000
explorer 0x0040a54b 0x000aa000
sfc 0x0040a54b 0x000a9000
skype 0x0014a54b 0x001b7000
firefox 0x0014a54b 0x001a7000
regedit 0x0040a54b 0x00b9000
Strangely, this does not happen on some executable if they are launched early, but only after some time into the startup: for example: skype starts normally when at startup, but if I close and reopen it, it won't start and give me the error.
Some programs start normally at startup, ZoneAlarm Antivirus is among these.
This happened after I have removed a malware infection:
this morning at startup I had a popup in the lower right corner, telling that my pc was infected and i needed an antispyware. I have ZoneAlarm Antivirus and Firewall installed, but ZoneAlarm's TrueVector service had been disabled by this malicious software, and Spybot would not start either. ZoneAlarm Antivirus' update did not work. This malicious software autonomously downloaded and installed a so-called antispyware named XPSecurityCenter, which is surely spyware itself.
I had some Windows automatic updates left pending, and I installed them: among them there was the Windows Malware Removal Tool.
After rebooting, the popup was gone, and i saw a brief message stating that some malware had been removed (I think the windows removal tool removed this spyware, but I'm not sure). ZoneAlarm started working again.
I rebooted again and this time all those messages started to show up.
At this time, I can't run quite anything on my PC. Can somebody please help me?
