Good day. Symcuw.exe is a SymCUW
from Symantec Corporation
belonging to Symantec Shared Component. These means you have a symantec antivirus or software installed in your system. You can easily remove it by using Malwarebytes - Anti malware. You can get it on this link:
please see to it that the product is genuine When live update fails, it is most likely due one of the following reasons: ·No license file (*.slf) is installed ·The installed license file (*.slf) has expired ·The trial period has expired ·The installed license file (*.slf) has been deleted, or become damaged or corrupted ·The software is not able to able to communicate with the Symantec servers
No license file (*.slf) is installed It is necessary to have a valid license file installed into the program to authorize it for the download of the content updates using Live Update. It
is necessary to register your license(s) at the Licensing Portal
(https://licensing.symantec.com/) to generate the license file if it
was not included with your license certificate (*.pdf).
The license file (*.slf) has expired It is required to have a current support contract to be authorized to have the most current content updates
downloaded. If you have renewed your support contract, it is necessary
to register your license(s) at the Licensing Portal
(https://licensing.symantec.com/) to generate the new license file if
it was not included with your license certificate (*.pdf). This
could also be the case if you have a current support contract, but had
a trial license key installed in the software. It is necessary to
register the support contract renewal to generate the new license file. The trial period has expired
of Symantec's products offer a limited-time trial period where you can
test the software in your environment. When the trial period expires,
the software will typically cease to function as part of the Trialware
The installed license file (*.slf) has been deleted, is damaged or corrupted If
the license file that was installed in the program has been deleted or
is corrupted, it is necessary to reinstall the license. You
can re-download the license file from the Licensing Portal account the
license was registered in. If you registered the license into your
Licensing Portal account, you can log into your account and re-download
the license file. If the license was registered into the account of
another person, you would need to contact that person to have them
re-download a copy of the license file or provide you access to
re-download the license file from their account.
The software is unable to communicate with the Symantec servers The Symantec software must be able to establish a connection to the servers to be able to download the current content updates. If the software is unable to establish the server connection, then it will not be able to download the content updates. You
would need to check your network security settings to ensure the
network traffic is not being blocked. If you believe your network's
security settings might be blocking the Symantec software from
communicating to the Live Update servers, contact Symantec Technical Support for assistance. You can find the phone number for your region here:http://www.symantec.com/business/support/contact_techsupp_static.jsp One
example of this occurring is when trying to install a license file into
Symantec Mail Security 4.6 or later you get the following error
message: "Symantec Premium AntiSpam registration failed. The product will not receive definition updates". Here is a link to a technical support document with more information on this issue and possible resolutions:http://service1.symantec.com/support/ent-gate.nsf/854fa02b4f5013678825731a007d06af/e0395129f0bedbf4882570d2006ad1af?OpenDocument

Symantec Norton anti Virus is a real pain in the neck. it blobks everything when you install it. go to Symantec Control Panel or Norton Anitivirus' Control panel. then choose Allow Yahoo (or your Application) to acces the internet. for more help. visit. www.symantec.com
Norton Antivirus 2005 has lots of errors and problems specially with its updates and also its virus scan is not reliable. Norton 2005 can also corrupt your windows while updating itself its better you uninstall it completely and go for Norton 2007 or my favourite Mcafee Total Protection 2007 which has no problems with updates and has anti spyware, registry repair and lots of things. You can also go for AVG Anti Virus which is quickest of all
