what is the security processor loader driver win7?

Question

In device manager under plug and non (hidden devices) there is a yellow exclamation, however properties reveals no issues.  Is this something to be concerned about?  Because my laptop HP is running terrible.  Its unresponsive and very slow, will work fine in SafeMode most of the time.  I'm wondering that McAfee might have something to do with these issues being this was the last program installed.  The problems occur in Win7 and Firefox.....the activity indicator just spins and spins.  Shutting down is another issue takes a very long time.

Answer 1

Dear David,

Thank you so much for writing this down. I was at a total loss and didn't know what to do. My laptop has frozen and would only start in safe mode after a recent windows update.  The system didnt recognize that I was working with a legit MS software and kept closing all applications.

It is now 3.40 am and after following your clean boot process I managed to get back my system in normal mode and the software key is recognized!

I hope it stays this way. I will turn off windows updates for now.

Thanks once again.

E.

Safety Scanner

The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.

If you can't download or run the Safety Scanner, Windows has a tiny anti virus program built in. It only targets the most common threats. It will want to update, see if it works. If not run it anyway.

Click Start - All Programs - Accessories - Run (or press Winkey + R). Type

mrt

You can reset your firewall to default settings.

Start - All Programs - Accessories - Right click Command Prompt and choose Run As Administrator. Type (or copy and paste by right clicking in the Command Prompt window and choosing Paste).

netsh advfirewall reset export "%userprofile%\desktop\Firewall Settings.wfw"

For a permanent anti virus, we here in the forums notice a complete lack of problems for people using Microsoft Security Essentials.

You are asking in a Windows Vista group. Post in a Windows 7 group. Tell them what you have already tried and exactly what happened.

If it works in safe mode try clean boot troubleshooting.

Each of the two steps turns of programs, services, and drivers in increasing amounts. Thus narrowing down the possible culprits.

Clean Boot

Click Start - All Programs - Accessories- Run and type

msconfig

Then go to the Startup tab. Untick everything. Then go to the Services tab. Tick Hide All Microsoft Services and untick everything that's left.

Reboot. If this solves your problem reenable ½ of the services/startup items until you find which one.

Advanced Clean Boot

If the above doesn't help.

Download Autoruns from http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx

Start the program by right clicking and choosing Run As Administrator and click Options menu - Filter Options and tick Hide Microsoft entries and clear Include Empty Locations. Untick everything left.

Reboot. If this solves your problem reenable ½ of the items until you find which one.
