Well the windows error 26 = The specified disk or diskette cannot be accessed, which doesn’t seem to make much sense when related to a file.
So I can’t see why the file in the temp internet files folder would be inaccessible. The .mct file type is a MapCharT file, what exactly that is I don’t know exactly, but google seems to, http://www.google.com/search?q=.mct+file+type. Now if this is something like a google earth style map, perhaps it is protected so you can’t copy it, I don’t know. What I do know is I wouldn’t be unduly worried about it unless I was getting avast errors displayed on the screen and not just in the logs.
I don’t look in the logs unless I get a avast displayed error, much of what is in the logs is verbose and of more use to the programmers, so I tend to keep out of there for fear of frightening the horses ;D
I’m sorry, but is value of 00000026 hex or decimal? If hex (it’s looked like format %08X) that decimal error code will be 38
(ERROR_HANDLE_EOF 38 Reached the end of the file)
I can suppose that this error should be thrown when size of file is 0).
I made an assumption (you know what they say about assumption ;D) based on the fact it is an avast AAVM scanning error that it was a file system error, so I just checked the windows error codes using a little program, MSWinErr.exe.
Since it is a temp internet file location even if it were 0 byte size it shouldn’t cause any real problem, though it would be nice to know exactly what the warning related to, if only the avast warning/error log info was more user friendly.
