Since there are no OS X viruses that have been identified yet, that's probably not the issue.
I ordered this 500GB hard drive from Brand Name Manufacture for only $43 (which is actually an upgrade from my original 250GB one) and although I chose 3-5 day.
- The Clean Drive tool in Parallels Toolbox. The Clean Drive tool, one of the more than 40 tools in Parallels Toolbox, is tailor-made to help you manage free space on the Mac Hard Drive, especially in the area of files that you really don’t need, like log or cache files, or the temp files created by some Mac apps. (See Figure 2.).
- If you want to make use of your Mac's Thunderbolt port, then this is the best external hard drive for Macs. It provides twice the speeds of standard USB 3.0 drives.
There are a few possibilities. The most common one is when a user is using an application, inadvertantly slides the pointer to the desktop and selects a file, then begins to type (renaming the file). It's pretty simple to do, though most of the time you notice.
The next possibility is that there's errors on the disk. Use Disk Utility to check the disk for errors and repair them, if possible. This sort of problem manifests itself a peculiar file name changes, messed up file permissions, etc. This can occur a number of ways, as the result of hardware issue, as a result of sudden shutdown at the wrong time (though, if using journaled HFS+, there should be little chance of that), or if you accessed the disk using a different OS (e.g., if using Boot Camp and Mac Drive and you don't unmount the disk properly).

Before you can access a new or formatted drive in your operating system, you need to initialize it first and then create a partition on the drive. A partition defines an area of the drive to use for storing data. The partition uses a file system (for example, HFS+, ex-FAT, NTFS, and so on).
Initialize a drive
Mac OSX detects a drive that needs to be initialized and automatically prompts you to initialize the drive. If you are prompted to initialize the drive, click Initialize. If you are not prompted to initialize the drive and you cannot find the drive in Finder, you will need to create a partition on the drive.
