Last week I read this piece about how
Windows XP [is] at risk as antivirus vendors jump ship and the unanswered question “why are they doing this” left me thinking.
After thinking, I have the answer: “Money”
The Antivirus vendors will put their efforts where the sales are. Looking up the latest statistics of operating system usage shares at Wikipedia, it is correct that almost 40 percent of PCs are running Windows XP, but who knows bow many of those have owners that will buy antivures software? (well, Microsoft knows how many are licensed, but I doubt they will tell me). However, the statistics do not mention how many of those XP installations are corporate, but those that are, should be busy complete ting upgrade to Windows 7 before April 2014. For the consumers that still run Windows XP on their PCs, I dare guess that they have a healthier IT/life balance than me, and so give ITinvestments@home lower priority. But even if they did otherwise, much hardware with Windows XP OEM installations and full service pack and security updates would struggle to run antivirus suites intended for newer, more powerful hardware platforms. I can also imagine that some of those older XP machines have in fact been replaced by tablets that satisfy the same user needs as the older PCs.
A real world example: I am writing this entry during a family visit while installing Win XP Service Pack 3 on a 2005 Laptop, powered by a since core 1.73GHz CPU. It did have antivirus installed upon delivery, but that was uninstalled when the laptop’s performance degraded over time.
Regardless the motives of the Antivirus vendors, this story just confirms that staying on Windows XP is a risky affair, because we can be fairly certain that at least the malware vendors will continue to support Windows XP for a while.
