"Your virus protection cannot be updated." This error occurred after an update to the software and refused to allow daily updates. Though the bug was reported in 2004, it was not corrected for the 2005 or 2006 versions. Another incident occurred in May 2007, when Norton AntiVirus flagged components of the Pegasus email client as malicious, rendering the program corrupted. Symantec customer service addressed the problem by running through a checklist of troubleshooting steps which were not always successful. Faulty update On July 25, 2006, Symantec released a faulty update for Norton AntiVirus 2006 users. Users reported an onscreen message stating "Norton AntiVirus 2006 does not support the repair feature. Please uninstall and reinstall.". Symantec claimed the faulty update was downloaded to customers between 1:00 PM and 7:00 PM on July 25, 2006. Symantec developed a workaround tool and has listed troubleshooting steps, available here. The company released a statement, stating they expected to deliver a repair patch to affected users by Monday, July 31, 2006." Uninstallation Norton AntiVirus has been criticized for refusing to uninstall completely, leaving unnecessary files behind. Another issue is versions prior to 2009 installed LiveUpdate, which updates Norton-branded software, separately. The user must uninstall both Norton AntiVirus and the LiveUpdate component manually. The LiveUpdate component is purposely left behind to update other Norton-branded products, if present. In response, Symantec developed the Norton Removal Tool (SymNRT) to remove leftover registry keys and values along with files and folders. However, neither route of uninstallation will remove subscription data, preserved to prevent users from installing multiple trial copies. SymNRT can only remove these Norton programs: Norton AntiSpam 2004 and 2005 Norton Antivirus 2003 through 2012 Norton Ghost 2003,9.0,10.0,12.0,1 A.O and 15.0 Norton GoBack 3.1 through 4.2 Norton Internet Security 2003 through 2012 Norton Password Manager Norton Personal Firewall 2003 through 2006 Norton SystemWorks 2003 through 2009 Norton Confidential Online 2007 Norton Add-on Pack 1.0 – 4.0 Norton Save and Restore 1.0 through 2.0 Norton 360/Security Suite/Business Suite 1.0 – 5.0 Norton Safety Minder 1.0 Norton Safe Web 3.2 Once SymNRT has started the removal process, it cannot be stopped. It is recommended to close all running programs prior to running SymNRT. ACT! and WinFax users are recommended to back up their databases before running SymNRT. Incompatibilities with ZoneAlarm Norton AntiVirus 2007 will not install alongside ZoneAlarm. This incompatibility has caused annoyance for Norton customers who purchased Norton AntiVirus
