unable to update the antivirus on Mobile device via GPRS.

I understand that you are unable to update the antivirus on Mobile device via GPRS. Am I correct?
I have an issue on Symbol MC70 device
we have around 150 MC70 devices accross Asia Pac with the same issue
May I know when did the issue start?
McAfee Virusscan Mobile version 1.2.0.0023
ever since we have installed antivirus
I can connect to GPRS and browse public web pages
but when I try to update anti virus comes back with an error "update failed"
This may happen if there is any temporary issues with our download server or there are any incompatible software on the mobile device.
Do you have any other information that you think may help us to provide correct resolution?
only other application we are running on the devices are Check point secure

I recommend that you perform the following steps:
1. Click Start on your phone.
2. Scroll down and click More.
3. Scroll down and click More.
4. Click McAfee VirusScan.
5. Click Menu.
6. Click Configure Options.
7. Choose the Updating Option you prefer and click Done.

After this, disable the "Check point secure VPN client" temporarily and then perform the following steps:
1. Click Start on your phone.
2. Scroll down and click More.
3. Scroll down and click More.
4. Click McAfee VirusScan.
5. Click Menu.
6. Click Update VirusScan.

Performing these steps should resolve the issue.
NOTE: The products must be registered with McAfee to be able to update regularly.

Okay. In this case, you can disable the "Check point secure VPN client" temporarily and then try to update the VirusScan mobile software.
under update options > i have non of the boxes checked with a tick
first > update without prompt 2. update at internet connection 3. update at restart
then schedule updates > interval : weekely

Okay, we will try one more time. After selecting the "update at internet connection" option, click Done
Then disable the "Check point secure VPN client"
NOTE: This is temporarily. We can enable it again after the updates are
