Microsoft Security Essentials couldn’t scan the computer.

Microsoft Security Essentials couldn’t scan the computer.

Try to follow the following procedure to solve the problem. First of all make sure that you have updated your. This problem will be resolved automatically if you updated your “Microsoft security essentials” from the website of Microsoft, but it’s only for Windows 7. If you are using windows XP, then you must have to follow the given steps:

Click on Start and open RUN.

Then type REGEDIT and press enter.

Go to HKLMsoftwaremicrosoftwindows ntcurrent versionprofilelist.

At this point you can see several branches. Each branch beginning with S-1-5. You have to find a value called “profileimagepath”. If you don’t find this value in the first branch move to the next branch until you reached the last branch. If you don’t find this value, then you have to add it manually. To add this value Right click on the right hand pane at free space and select ‘New’ option.

Then select REG_EXPAND_SZ. A new value with name “New Value #1”will appear. Overtype the value with “profileimagepath”.

Now Close Regedit and recheck and add the value for any other keys in the profile list branch, make sure at least a blank key with the name “profileimagepath” must be there. Now close regedit and restart your computer. Now scan your system with “Microsoft security essential”.

Thank you Lesten Pasio! It took me awhile to update my Windows, seems like a lot of new and updated files were installed. After rebooting, I can’t still scan my computer. I followed your steps in running REGEDIT and found one branch without a value of profileimagepath. After the reboot, the scan works perfectly.

Thank you very much for the help! Also to Galarpe Miloni.

Hi  Jones 

There’s no problem with the real-time scanning of Microsoft Security Essentials, the status says that your computer is still protected. Your only problem is when you are doing a manual scan of your hard drive. There is another Techyv post which is described about this problem too. So visit that page and get more idea.
