Project description:
"Our website was recently hacked and we think they are still in there. I need to hire someone to clean up our website/server to make sure we are secure again.

1. From the forum posts I have read, we might have several vulnerabilities with some modules, and could have issues with more.
- [login to view URL] - [login to view URL]

2. A Paypal payment module was turned on in OC/Admin with an account/email that was not ours, and our [login to view URL] account was turned off. I turned off Paypal and turned back on [login to view URL]

3. We have had 1 report of a compromised credit card after using it on our website, could they be skimming our [login to view URL] module?

4. We are also getting MySQL errors at times with the website, both front end and admin area. "Fatal error: Uncaught Exception: Error: Could not make a database link using...." If I refresh the page, it usually comes back. Bot Attack?

5. There are probably more issues we are experiencing, but I just have not discovered them.
