Symantec
As a leading provider of antimalware software, Symantec boasts a great online database of virus and other malware definitions. If you want to see the definitions for a particular month, just select this month in the list. You might wonder why you see so many pests that have been first reported in 2005, 2003, or even before that but since these pests are still alive and kicking and your computer needs protection against them, they are listed here.

Commtouch – The Malware Outbreak Center
The malware outbreak center of Commtouch is one of the most precious resources about viruses discovered in the last days. If you need really recent information about what new viruses have appeared in the last week or even day, chances are you will find it there. One of the greatest features of this site is that it shows a list of viruses, the programs, which detect them and the name under which the pest is listed in this program. Yes, you read correctly, one and same pest has different names in the pest databases of different antivirus programs.

Tech Support Guy
Proxy virus is another major pest you can get online for free. As with any really dangerous pest, Proxy Virus is easy to catch, hard to detect, and many antimalware programs can’t fight it. If you have already tried a couple of times to remove it with no success, you might want to see if this thread is not the solution you have been looking for.

The Site of Tobias Engel
Tobias Engel of the Chaos Communication Congress discovered in December 2008 a really dangerous virus that affects mobiles running the Symbian OS. The virus is poetically called the “Curse of Silence” and it is pretty evil because while the mobile is affected, it will not be able to receive SMS and MMS messages.

Cyber Defender
This is one more service with real-time alerts of new threats. The list is updated regularly and you can see even viruses discovered minutes ago. The list includes mainly pests of higher severity but occasionally low severety and moderate severity pests are reported as well. The site also offers a list of phishing alerts, so if you want to stay ahead of security risks, check here frequently.

Bleeping Computer
The Trojans from the Vundo family are not that new but newer and newer versions are released quite often. The Vundo Trojans, known as WinFixer, Virtumonde, Msevent, Trojan.vundo, and some other names, vary from relatively harmless to very dangerous. The Vundo family pests are very widespread and that is why they need really a lot of efforts to get rid of. If you want to learn how to do it, the resource in the link will tell you.

Virus.gr
The charm of this site is that it regularly publishes results of tests of popular antimalware programs. The latest versions of these programs are tested and rates are given to each. This way users have a relatively recent information about which program protects them best. No single program offers a 100% protection but some of the programs are virtually helpless against new threads.

Sophos
This RSS feed is good for everybody, who wants to receive real-time notifications of recently reported viruses. The feed is updated relatively frequently but as with almost any of the similar services listed, there is no single malware alert service, which covers absolutely all viruses. That is why if you want to stay informed about the latest threads, you need to keep an eye on several malware alert services.

The Nation Multimedia
The resource in this link is a chart by TrendLabs of the Top 20 viruses in history. Anyway, many of these viruses are history already but some of them are still present (generally in a mutated form) even nowadays. The destructive power of many of these viruses is much more severe than the destructive power of many of the viruses discovered in recent years.
