Windows Bootcamp Partition quit working

[c809a376]

Hi, I just recently bootcamped my computer and started running Win7 on it. Everything worked until last night I was cleaning up some files in OSX, repairing permissions, installed Sophos antivirus software, etc.. Today when I tried to boot into the Win7 it says Insert bootup disk or something along those lines on a black screen.
So I started OSX and looked at the diskutil in which my Bootcamp partition is now labeled disk0s4 and will not mount. I tried repairing and it says:
Invalid BS_jmpBoot in boot block: 000000
Volume repair complete.
Updating boot support partitions for the volume as required.
Error: Disk Utility can't repair this disk...,disk, and restore your backed up files.

When I run the bootcamp utility it says I still have Win7 installed, or rather it gives the option of Uninstalling Win7.

Diskutil Info says the following:
Device Identifier: disk0s4
Device Node: /dev/disk0s4
Part of Whole: disk0
Device / Media Name: BOOTCAMP

Volume Name:

Device Block Size: 512 Bytes

Read-Only Media: No
Read-Only Volume: Not applicable (not mounted)

What is going on here?

I'm running OSX Mavericks, Bootcamp 5.1.2, rEFIT, and Win7.

Thank you very much!

Can you run a repair from a win 7 boot disk?

When you say Win7 boot disk do you mean the Win7 install DVD?

Contact Sophos.

Why would I contact Sophos?.... Is this software known to cause issues with bootcamp? I'm actually uninstalling Sophos right now because it has been making my computer extra laggy and I read that Mavericks has its own maleware and a-v protection already.
