It is Software Doctor that now appears to me to be on steriods. Note each time you boot up, it hogs memory and increases a corresponding svchost.exe file. Together upon startup, or while running a scan Spyware Doctor usurps system RAM, slows your other processes loading, essentially it takes over your machine. YOu can go to your Task Manager and disable it and the corresponding svchost.exe it uses for unknown purposes, wiping them both out. Of course you first need to wiegh the benifit/risk to surfing without SpyDoctor. I use the primative method of disabling it when I need speed.

I work at staples. I was doing a diagnostic on a very very slow laptop and found swdsvc.exe was taking over 243 MB of ram on a machine that has under 1 gig of ram. Honestly no spyware protection should come any ware NEAR that amount of ram, i don't care how effective it is.
It is not part of Windows from beginning, came with some sw and is eating my resources.

Best practices for resolving SWDsvc issues

A clean and tidy computer is the key requirement for avoiding problems with SWDsvc. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the SWDsvc.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
