Where can I find this corrupt file? I can't find it anywhere.

Question

It's driving me nuts because I keep seeing it whenever I run my anti-virus scan. Whenever I search for the thing, I can't seem to find it anywhere. This can't be possible. I don't know if I need to give you my exact username for this computer, but as a stand-in for that, I'll just type [ANONYMOUS]. The corrupt file is named as follows-
/Users/.[ANONYMOUS]/[ANONYMOUS].sparsebundle/bands/33f
Is there any idea where I can find this?
And if possible, is there a way to recover it or do I just have to delete it? I've found a couple of corrupted google chrome files that I've taken care of so far.
One last question. Is this file's corruption a symptom of hacking? It's a long story. Just curious...

Looked at what they do and how they do it, antivirus tools are arguably difficult to distinguish from the malware itself, and problems with the tools can sometimes manifest themselves with corruptions and crashes.
While thomas_r. points to the mv rename command (which will work — just be very careful to include exactly two spaces in that entire command, don't add additional spaces within the directory names), that rename operation might mess up the antivirus — I'm guessing that file is part of that package — and I'd start out with something like the following commands to look around at that .yourshortname directory:
ls -aled@ /Users/.yourshortname
ls -ale@ /Users/.yourshortname
The first looks at the settings and attributes of the directory file itself, and the second looks at the settings and attributes of any files stored in the directory.
If you're encountering corrupt files, that can imply a software or hardware problem is lurking.  As a first step, I'd remove the antivirus tools — again, these tools are very close to being malware, in terms of what can happen when they go wrong — and see if the corruptions persist.  I'd also verify you have current backups at all times, on the off chance that this is a hardware problem — that's your path back from both software and hardware errors.  A failing disk can also cause file corruptions, and that doesn't usually end well.
Full disclosure: I'm somewhat skeptical around the value of antivirus on OS X for most users.  Antivirus chews up a non-trivial amount of resources and can itself cause problems and false positives.   There are very few bits of malware around that are specifically targetting OS X, and shuting off or removing or plugin-blocking Adobe Flash Player and Oracle Java, and disabling features such as Safari's habit of automatically opening safe downloads, then the integrated features of Gatekeeper and XProtect and OS X security should keep you fairly secure.  This all assuming you're reasonably skeptical around what you click on and what packages you install and particularly if you're not off looking to load cracked software from the torrents, and are not installing and running stuff (anything that you didn't go looking for yourself) found from random places around the 'net or from random mail messages sent to you.  Even the best antivirus around isn't entirely proof against any of those sorts of attacks, either.  If you do decide to use antivirus (and that's entirely your call), then please do not assume it will effectively protect you; you'll still want to avoid loading anything that might reasonably be malware.  Expect it to toss false positives, and to potentially cause flaky behavior and — as has happened with various malware tools, and sometimes successfully — to itself be targeted for attack or used as a backdoor.
