Yeh perhaps.

Plenty of other guides here though.

Almost weekly here we find major performance problems caused by MucAfee. I would immediately uninstall it and replace with Microsoft Security Essentials. Then run a Full Scan.

Next work through these troubleshooting steps to see if you can find other causes for your problems. The steps lead up to Repair Install or possible Reinstall. If you want to jump to reinstall at least test your hardware first to clear it.

Tips for getting a Perfect Reinstall

This is getting a real pain now. I am attempting to open windows in safe mode. It doesn't allow me to. Although I can open safe mode with networking!! I attempt a repair at boot up, but again I am thwarted. I have also tried to run SFC in the command prompt. but nothing happens. (I am running as the admin). There has to be a suitable solution to this

Have you already uninstalled MucAfee and replaced with MSE or Avast?

Try running Malwarebytes full scan from Safe Mode with Networking.

If it won't run, download and burn to CD or write to flash stick Microsoft Standalone System Sweeper, boot it to run a full scan. Then try again running SFC -SCANNOW Run in Command Prompt at Boot

Try running System Restore from System Recovery Options to a point before the problems began.

Try running a pass with Startup Repair as well to see if it finds problems in the boot.

Okay I have manged to rum SFC /scannow in safe mode. I have corrupt files that were not all fixed. I did try this method several times. I have also tried to attempt a repair at the boot up. However this was unsucessful. It says "Windows failed to start" i I'm not sure why, i think it is because I have the standard OEM DVD edition of Windows 7. I am thinking that I will need to do a restore. How long does that take and does it need to be done in safe mode?
Thanks

Hi Blueknighuk, you do not need to be in safe mode, you can either use the built in Restore method, or use the boot one by repeatedly pressing F8 during bootup which is the one I prefer, and select a time before the problem happened. It usually takes up to 30 minutes, no longer than an hour, depending on how much files needs to be restored and how fast your computer is.

Make sure to backup your important files before proceeding.

Good luck.

Joe.

After I ran the SFC /scannow function I attempted to try to start in safemode. I got a bit further than before and it hung at classpnp.sys. I did a bit of looking around the internet and found others with this problem who had loaded fallout 3. This is a game that I loaded for the first time a few months ago. Looking back I can see this may be the cause of the problem. I thought I would share that.
Also does a restore remove emails in Outlook? I will backup the PST files along with all other essential files just in case. I have never done a restore before so apologies if this is a silly question.

Hi Blueknighuk, Restoring will not remove all your e-mails in Outlook, since it is an external program and your mail is an external place. In order to get your mail back after restoring, just re-download it if the restore doesn't have it and press Refresh or Reload mail and it will restore everything.

Are you referring to System Restore?

You can run it from Safe Mode or System Recovery Options, which should be on the second screen after booting into a WIn7 Retail OEM Installation DVD.

Or are you referring to Factory Recovery run from its partition or Recov disks?
