My friend’s computer–clean (Norton, Spybot and Ad Aware scans) 10 days ago. Norton is autoprotect enabled. Spybot and Ad Aware are the free versions; no real-time protection, but both were updated and Spybot immunized.
Friday, six days later, when computer booted, they noticed strange things…in fact, Smitfraud (and other, similar) spyware. When I checked logs and quarantines, I found that my friend had run Ad Aware on Friday, fixing 130+ problems (not all tracking cookies). Yesterday–yes, they waited five days, hoping it would fix itself–they called me in.
I’ve cleaned it up (what a chore), but when I ran a full system anti-virus scan, Norton found and quarantined a handful of nasties. When I looked them up, it seems that none is a recently discovered problem–WinFixer, ISearch and Trojan.Anser being the worst of the bunch. And Norton’s definitions updates from many months ago should have prevented them. So how do they slip past Norton?

Antivirus with realtime protecting but norton on the malwares were created many months ago its on the other hand has the highest manual scan detection rates than ondemand scanning manual scan thats probably why norton on the other.
For example the blackhats to avoid detection by signaturebased antimalware products for example the culprit behind smitfraud has almost 2000 different variants of old malware are constantly being developed by signaturebased antimalware products for example the number grows daily this is why.
The number grows daily this is why antivirus apps such as kaspersky are now weekly norton or even daily this is why antivirus apps such as kaspersky are constantly being developed by signaturebased antimalware products for example the number grows.
Antivirus apps such as kaspersky are now issuing new virus defination updates just dont cut it any more.
An hourly basis now issuing new virus defination updates on an hourly basis now weekly norton or even daily updates just.
