Hi,
  In my system, i have a virus problem so i download AVG 8.5 and scan. After scan complited, my virus program is finish but now when i start xp, outlook express error displyed on desktop and outlook can't open. When i switch to microsoft outlook, only account imported but mail is failed to import. How i get a mail from outlook express. When i try to import messages, "Failed to import message, another program may be USING this" error pop-up.What i can do now for recovaring mails?Sounds like corrupted data which will not export. What virus's did you have so we know the type of ATTACK you had to try to see what damages you have to your system.

Generally a system that once had a virus or virus's can never be trusted to perform correctly or be used for secure computing as for ROOTKITS etc could have opened your system up for information theft etc.

A clean rebuild is always suggested if this system is to be usde for online banking or PURCHASES or any personal information usage.

You may need to consult in a person who can run a repair utility against the OE database where the information is stored.

Do you get any specific error messages pointing to dll's missing or anything ELSE that would point to corruption? ( You stated there was an error message...what did it say )
