Someone hacked my server (most likely through an exploit on an outdated version of OsCommerce.
I need someone to properly scan the VPS and find all infected file, spyware, malware, etc.
Then remove the files, update all of the software such as OSCommerce, and prevent this from happening again.
To sum up the job, it's:
1. Find holes
2. Patch them
3. Remove infected files
The files are across multiple domains.
