Error: "3048,3"

Got this error today. I did everything it said at Norton support since the fix for the error didn't install when it popped up: https://support.norton.com/sp/en/us/norton-antivirus/20.3.0.36/solutions/v63747322_EndUserProfile_en_us?actstat=activated&buildname=Retail&conntype=100000000&coreservice=Startup+Type%3Aauto+State%3ARunning&cpu=x86+Family+6+Model+15+Stepping+13&curdefs=20130302.016&datetime=03-03-2013+20%3A13%3A59+PM+GMT&defbrowser=Firefox&dsfree=114.67&dstotal=244.23&endpointid={54788A1E-1021-44DA-A1A2-2044961D2A77}&entsrc=CED_Selfheal&env=prod&error=3&hbguid=54788A1E-1021-44DA-A1A2-2044961D2A77&hcmode=false&heartbeatID=54788A1E-1021-44DA-A1A2-2044961D2A77&ieversion=9.0.8112.16421&layout=Retail&layouttype=ESD&lic_attr=21124114&lic_type=16&memload=77&memtotal=1732&module=3048&os=windows&oslang=iso%3AENG&oslocale=iso%3AUSA&osvers=6.0&osversion=6.0+6002.18765.x86fre.vistasp2_gdr.130104-1437&partnerid=1000670&partnername=Retail&plang=sym%3AEN&plgid=1&plid=1&product=Norton+AntiVirus&psn=HKDD2WV93JH2&remdays=135&sessionid={FF11F5AE-DB47-4472-A6F3-4E64EF3948E2}&skuf=21171506&skum=21234031&skup=21172521&spversion=2.0&sublength=135&subremaining=135&substatus=current&symskucurrent=21172521&symskumedia=21234031&utm_medium=product&utm_source=symc&vendorid=1000670&version=20.3.0.36

 

Downloaded 20130302-016-v5i32.exe file from http://www.symantec.com/security_response/definitions/download/detail.jsp?gid=n95 but said install files are corrupt. So I ran Norton Power Eraser and it removed 20130302-016-v5i32.exe file that I just downloaded and it the said the file was bad. What should I do?

 

I have Norton AntiVirus& pc is Windows Vista Home Premium 32 bits
