Bitdefender VShield service (core component)

it jams up my disk and makes my pc hell of a lot slow.
BitDefender AntiVirus Suite - can destroy your drive by scanning for viruses all the time
I don't know anything about the vsserv.exe file, but I went to the program file and ran the fix program cycle on Bit Defender and the process stopped running. All still seems OK with my computer and Bit Defender. Seems like Bit Defender was upset by another program I had loaded, which I also uninstalled.

Essential to any bitdefender, scans files for viruses
It may not be a threat, but it surely jams up my processor and anything I am doing. BitDefender fixed this once before, now fix it again!

Seems to be part of "Immunet" as it's been running since I downloaded that software ! My "Bit Defender" is not 'running' now and is not nearly to consuming of my computing resources. Immunet does not seem to be what their sales puff seems to be running constantly consuming 100 percent of my computer's capacity !! I thought it would be 'cleaning' internet content before it got into my computer ! May have to 'uninstall' as I my computer is quite unresponsive as it seems to be running in the background all the time, without even pausing when I am using my computer.
vsserv.exe is also part of ACRONIS BACKUP AND SECURITY 2010

Best practices for resolving vsserv issues

A clean and tidy computer is the key requirement for avoiding problems with vsserv. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
