I have decided to change my anti-virus software from CA's eTrust
Antivirus to McAfee.  I have a PC running Windows XP.  In the process
of downloading McAfee, I recieve a message indicating that it cannot
operate all components (e.g. virus scan, antispam etc) while other
eTrust programs are operating.  I have used the "Add/Remove Programs"
function to remove eTrust, but I am still receive the same error
message.  How do I complete remove eTrust in order that McAfee will
run completely on my system?

Does the information on this website allow you to remove eTrust?

http://tech.torc.k12.nm.us/techclass/

I would also suggest you seek another antivirus aside from McAfee. 

Avast, NOD32 and Sophos are some much better alternatives. According
the virus bulletin network the best antivirus on the market is NOD32
and has been for the past 7 or 8 years now.

http://www.nod32.com
http://www.eset.com/products/compare_heuristic_detection.php

"NOD32 has the best detection in the industry, and protects against
95% more new and evolving threats than McAfee, Symantec and Trend
Micro (AV-Comparatives.org)."

I used to swear by Norton and McAfee until I realised how poor they
were incomparison to other anti virus vendors.

Can you tell me what version of eTrust you are using?

Another option could be to follow this

http://www.cybertechhelp.com/forums/showthread.php?t=106741

"The usual way of doing this is to reinstall the program and then
uninstall it again.
If that doesn't work Look in C:\Windows for a file named UnVet32.exe,
if it's still there it means that EZAV didn't uninstall correctly.
If UnVet32.exe is still in C:\Windows you'll need to boot into Safe
Mode, and then click:

1. Start->Run->and type in: unvet32.exe
Pay attention to what the uninstaller displays, if it can't remove
something you'll have to delete it manually.

2. Depending upon how badly the uninstaller failed after you've ran it
you "may" need to manually delete the following:
* C:\Windows\AVShlExt.dll
* C:\Windows\System32\ISafeIf.dll
* C:\Windows\System32\iSafProd.dll
* C:\Windows\System32\VetRedir.dll
* C:\Windows\System32\Drivers\VetEBoot.sys
* C:\Windows\System32\Drivers\VetEFile.sys
* C:\Windows\System32\Drivers\VetFDDNT.sys
* C:\Windows\System32\Drivers\Vet-Filt.sys
* C:\Windows\System32\Drivers\VetMonNT.sys
* C:\Windows\System32\Drivers\Vet-Rec.sys
* C:\Program Files\CA\eTrust EZ Armor\eTrust EZ Antivirus
* The EZAV start menu program group located in Start->All Programs
* In the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\Ant i-Virus

If EZAV is the only eTrust software you've ever installed it should be
safe to remove in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates

If you had to manually remove any files run UnVet32.exe again to see
what it displays. If it displays a successful message it will delete
itself, thus a complete uninstall."

To keystroke.  I had previously found the eTrust removal tool, but
found that it did not work.  I downloaded it, and opened the tool but
nothing happened.

I'm not sure what version of eTrust I was using.  It was purchased in 2004.  

I was unable to log on to the crm.my-etrust page (even as a guest).

I have not been able to find the unvet32.exe.  I have gone through my
registry and manually deleted all "CA" or "eTrust" folders/files.  I
can't see any other files that remains.  I have also recently
restarted my computer and attempted to download the McAfee program
again.  Same result.  Your recommendation about other programs came
too late unfortunately, as I have purchased the McAfee software and am
faced with the cost having been expended.  It would be a double
disappointment if I cannot load the software and it happens to be an
inferior product!  My aim is to salvage something and have it
workingon my PC. It seems to work well on my laptop.

Close A's eTrust Antivirus from the taskbar then uninstall the
software, restart then install Mcafee software.

crl2006
this is what you can do, 

if the etrust software is not getting uninstalled , let it not be, you
can disable any service or startup agent from this software and then
try reinstaling the mcafee application,

Start >> run>> msconfig >>

clcik on the STARTUP tab on top right, click disable all >> click apply

click on the SERVICEStab to the left of startup, put check mark
against ***"HIDE ALL MICROSOFT SERVICES"*** click disable all and
click on apply, clcik on CLOSE

Restart the system when it prompts, on restart put check mark against
**donot show this message or launch system configuration utility at
startup** and clcik on ok

Reinstall mcafee 

WILL WORK LIKE A CHARM


***no issues for this coz you are asking windows to ignore and not to
load the services and startup that is not required for windows XP to
work, do remember to disconnect from internet before you do this****
