Many months ago. Its no wonder. And erm, if you meant the malwares were created many months ago, then please make it clearer.
So lets see. Usually real-time protection ( auto-protect ) have lesser detection rates than a on-demand scanning ( manual scan ). Thats probably why Norton did little in real-time protecting. But Norton on the other hand has the HIGHEST manual scan detection rate. Its on par with Kaspersky.
And also, anti-viruses naturally do very little in blocking off spyware and trojan. I say one anti-virus with real-time doesn’t do very much in securing your whole PC. I recommend getting Spyware Blaster and Windows Defender. Or not Spyware Terminator or Spyware Doctor from Google Pack. They all consist real-time protection, which will definitely help in brushing off those pesky malwares that anti-viruses don’t catch.
New variants of old malware are constantly being developed by the ‘black-hats’ to avoid detection by signature-based anti-malware products. For example the Zlob trojan, the culprit behind Smitfraud, has almost 2000 different variants and the number grows daily.
This is why anti-virus apps such as Kaspersky are now issuing new virus defination updates on an hourly basis now. Weekly (Norton) or even daily updates just don’t cut it any more!
