A startup program that requires a file called import.dll cannot find the file. The file could have been removed, possibly by an antivirus/antispyware scan, or the file is corrupt. Go to Start > Run, type
and click OK, then click the Startup tab and see if you can see the program that might be looking for the file. Untick the entry for that program, which will stop it from wanting to start at startup. Import.dll is not, as far as I know, a Windows file, so you wont do any harm.
