Malware continues to increase at a rapid rate. With the DAT-5516 release, scheduled for 4 February, the number of drivers in the DATs will pass 500,000. Half a million is a huge amount. I remember my first antivirus program, back in the ’80s, that had a count of about 80. I don’t recall the exact number, but it’s easy to place it into perspective. We add way more on a daily basis now.
However, our current count is not an absolute number of detected malware files; this can confuse many people. Drivers can be written very specifically, say one driver for one sample, but that’s not very effective. Most drivers are written to generically detect many samples. For example, one driver can detect 50 or as many as thousands of malware files. Therefore, the number of detected malware files is way higher then the half-million number reflected in the DATs. For another look at the complexity of counting malware detections, please see François Paget’s blog as well.
Initially VirusScan would focus just on true self-replicating viruses, mainly 8-bit (.com/.exe), MS-DOS viruses as well as boot viruses, which were prevalent then–and some still are today. Malware has evolved into many areas including, but not limited to, VBA, VBScript, JavaScript, 32-bit (pe-type .exe binaries) mass-mailers, 32-bit file infectors, mobile malware, adware and password stealers, and others. Nowadays the majority of malware is static Trojans.
There has also been a big shift by the malware authors. The first malware authors were hobbyists, writing to to prove it could be done, but today we mainly see malware that’s going after the money–password stealers, etc. Malware is often developed in professional environments, much like a business project with a plan.
Although there is malware for operating systems such as Mac OSX and the various Linux/Unix versions, most malware is still targeted at Microsoft Windows and its applications.

hi fans,
malware numbers alone arent interesting for me, the degree of danger is the thing that counts …
MK ultra
I agree, they will keep growing, I remember I had a bad case of Malware, I had to take it into a computer shop to get it fixed. I know have Malware bytes running on my computer just in case anything ever happens again.
… and of course they keep growing in size astronomically. Would be nice to see some thoughts from AVERT over what is being done to shrink them down!
