Heavily Modified OSCommerce website needs fixing.
Error code that no payment methods are available. Also, hosting account was hacked into and malware code installed in some files. Do not know the extent of malware code.
1. Restore and install payment modules for Paypal and check/money order so they are functioning correctly.
2. Check all oscommerce files for malware code and remove bad code so files are "clean"
3. Test to make sure all is working correctly.
