what OS have you got ?

Have you tried manually removint mcafee ( including the registry keys) and then doing fresh install ..

If you have windows xp and viruscan has worked before, try restoring your machine to an earlier state and see if that would work

Vshield Won't Load
Summary: A likely fix as to why VirusScan 7.0 will not stay enabled on Windows XP

Cause
This issue is usually caused because the NAIFiltr is not installed. This may be caused by repairing your VirusScan installation on Windows XP. This issue can also be caused by the Klez virus or other viruses. Make sure that VirusScan is updated and that you are virus free.
Solution
If you installed with a CD:

Insert the CD and close the 'Welcome to McAfee' window that pops up.
Open MyComputer | CD Rom Drive | VSP or VSC.
Look for a file called NAIFiltr.inf, or just NAIFiltr. (NOTE: Do not open the XP folder to find this. It will be directly in that VSP or VSC folder).
Once located, right click on the file, and then left click on Install.
You will get an hourglass for a minute, but won't see anything really happen.
After the computer seems to be done, close all windows, and take out the CD.
Re-enable the VirusScan, and then restart the computer.
Your VirusScan should load just fine now.
If you installed from a download:
Go to MyComputer | C:\ | Program Files | McAfee VirusScan 7.00 Retail
Look for a file called NAIFiltr.inf, or just NAIFiltr. (NOTE: Do not open the XP folder to find this. It will be directly in that VSP or VSC folder).
Once located, right click on the file, and then left click on Install.
You will get an hourglass for a bit, but won't see anything really happen.
After the computer seems to be done, close all windows.
Re-enable the VirusScan, and then restart the computer.
Your VirusScan should load just fine now.

"(NOTE: Do not open the XP folder to find this. It will be directly in that VSP or VSC folder). "

NAIFiltr.inf is on your mcafee disk. This is the file it wants you to find.Once located, right click on the file, and then left click on Install.

Ifyou downloaded it from the website then "Go to MyComputer | C:\ | Program Files | McAfee VirusScan 7.00 Retail
Look for a file called NAIFiltr.inf, or just NAIFiltr. (NOTE: Do not open the XP folder to find this. It will be directly in that VSP or VSC folder). "
Once located, right click on the file, and then left click on Install.

not really, when NAIFiltr is installin, it looks for a file called NAVFiltr.sys.  BUt it cannot find this file, therefore doesnt finish installing.

Windows ME and XP utilize a restore utility that backs up selected files automatically to the C:\_Restore folder. This means that an infected file could be stored there as a backup file, and VirusScan will be unable to delete these files. You must disable the System Restore Utility to remove the infected files from the C:\_Restore folder.

WindowsME


1. Right click the My Computer icon on the Desktop and click on Properties.
2. Click on the Performance tab.
3. Click on the File System button.
4. Click on the Troubleshooting tab.
5. Put a check mark next to 'Disable System Restore'.
6. Click the 'OK' button.
7. You will be prompted to restart the computer. Click Yes.

Note: To re-enable the Restore Utility, follow steps one to seven and on step five remove the check mark next to 'Disable System Restore'.
