ASP!CACTIVESCRIPTENGINE::GETAPPLICATION+27In w3wp__PID__6656__Date__01_08_2011__Time_01_42_46AM__281__First Chance Access Violation.dmp the assembly instruction at asp!CActiveScriptEngine::GetApplication+27 in \\?\C:\Windows\System32\inetsrv\asp.dll from Microsoft Corporation has caused an access violation exception (0xC0000005) when trying to read from memory location 0x00000000 on thread 29

recent events: server was being brute forced by hackers all of Dec and probably earlier, they weren't able to gain access but did get a virus on and blasted out spam. insatlled AVG and about the 17 or 22 latest patches. after that the app pool started crashing and the server has crashed a couple times since then. I am in no mans land as I am a developer and not a sys admin but I have to assume many roles. So I'm reaching out for help.

Sometimes I will see hundreds of these 'C0000005' scriptengine errors in the event log in a matter of seconds and other times just a few times an hour. I googled this line 'ASP!CACTIVESCRIPTENGINE::GETAPPLICATION' and got nothing. Its like the function don't exist or something. I have spent many hours google-ing to no avail and am now turning to the experts on the forums.

Thank you for your help
