the NORTON ATI-VIRUS is not working,,,,what i sure do?

Uninstall your current anti virus and replace with the better one. Some Antivirus and anti spyware programs have poor virus detection and removal capacity and even cause threats to your computer.For best protection, use both Avira Antivirus for Virus protection and NoAdware 5.0 for spyware, malware and adware protection. Always update your Anivirus and anti spyware regularly to maintain your protection. Avira Antivirus http://www.free-av.com/en/download/1/download_avira_antivir_personal__free_antivirus.html No Adware 5.0 http://www.savefile.com/files/1933682 Internet Security Info: AVG - Detects viruses but not all Kaspersky - better than others but some problems on the performance issues Nod32 Antivirus - low quality anti virus Norton Antivirus (Symantec) - always creating crashes/not recommended antivirus Mc Affee Antivirus - the same poor detection on viruses like nod32 Avast - good but with few performance issues

Update?

Uninstall and reinstall then get the updates again.
