There are two standard ActiveX controls installed in Windows: WScript and FileSystemObject that provide access to registry and filesystem for javascript programs. Both are intended rather for shell scripting and disabled in browser by default.
Generally, the answer to "is something possible in language X" question is "everything is possible if you find a binding for your language". In case of javascript, that would be scriptable ActiveX or XPI component.
I think that statement made by eBay that you can tamper with the registry is slightly mis-leading. Using FSO anyways.
A quick look into FileSystemObject reveals no specialized API for working in the registry which is required as the registry is not a plain text file. You can work with native files and quite possibly change the registry that way, but to change it according to protocol (properly)...probably quite difficult.
Although using that object it's quite possible to f**k up files permenantly. That I've done!

Browsers don't allow it. If any did, no one would use it.
Edit: Microsoft allows it for their website, however. I'm not sure if they do so through JavaScript, but they have unlimited access to your OS (if it's Windows).
Bottom line is no one can hack into your computer unless you give them permission (i.e. use the a crappy browser that is acts no better then a malware program)?
Or are there ways of hacking into any computer without a security program?

Unfortunately, yes. Every software, including browsers, mail clients, firewalls and operating systems contains security holes, and an experienced hacker can gain access to everything. There's no door that cannot be opened. ;(
