Disabled OST file error in outlook

I am using outlook and it gives me an error and then closes outlook. I believe there might be a problem with the files but I do not know how to go about it. If my files are infected by a virus or are corrupted, is there a friendly OST recovery solution that will scan these files and repair them? I need them to open in any form and if they will occur as PST on the downtime/offline exchange server, it will be okay.
