Windows Defender Offline (default Quick Scan) did not find any problems. I'm now running a Full Scan.
As I mentioned earlier, the updated version of TDSSKiller, using the default parameters, did not find any threats.
I can free up the startup; however, the problem is so random and inconsistent, I'm not sure how effective that will be. Of course, with the VSC service now disabled, the PC is working great!
UPDATE: Would it be possible for me to overwrite volsnap.sys from another source? And would that help?
I'm a bit concerned by your comment about a possible BIOS rootkit. Are you suggesting that the BIOS has been compromised? If so, could that result in TDSSKiller and Windows Defender Offline returning a false negative. How do you suggest I proceed?
