I just downloaded SpywareBlaster and as I go to open it I get a message saying "This program has been damages possibly by a bad sector of the harddrive or a virus." What should I do to fix this problem?

i have tried numerous times now to reinstall the program and still I get that error message.

There is a possibility that you had a bad download, did you try to re-download it from a different site.

Did you do the virus scans and run ScanDisk?
