Not running in Safe Mode

I am running 7 Pro 64Bit w/SP1.

My comfuser is running extremely slow. Once it boots to the desktop, everything just hangs:

  • taskbar takes up to an extra 30 seconds to show-up
  • if I type in the Orb Search Menu, wording takes over 15 seconds to show-up (if at all)
  • when I tap Ctrl+Shift+Esc, Task Manager takes almost 1 minute to show-up
  • and trying to run ANY application (even the simple Sound Recorder program from either 7/XP) takes almost a minute to start

I went into Safe Mode & tried a System Restore, but every point I tried gets me a registry denied message. I opened a Command Prompt under Admin. & ran MalwareBytes’, but the only ‘problem’ found is a Menu Setting I personally set. I then tried running Avast, but no matter which switch I use, I keep getting this: “cannot find main engine (126)” - which I cannot find ANY info about.

Anyone able to help me?

avast does not run at safemode…but avast have something called boot time scan

open avast > click scan button on left side > now look at the scan button…there should be a boot time scan option below it now…
