2.20 million machines lost their data and the number of machines that were infected has now risen to more than 2.3 billion.
The number of computers that were impacted has risen to 2.5 billion, according to research by security company Arbor Networks.
That number is more than the total number of affected PCs and servers combined.
The number was up from a figure of 1.5 million, according a statement by Arbor Networks that was released on Tuesday.
It said it is the highest number of infected machines since the company first started tracking infections in June.
The new number is significantly higher than the 1.2 million the company originally reported in August.
Last year, Arbor Networks reported more than 100 million machines were infected, up from less than 1 million in May.
More than 40% of all infected computers were Windows XP computers, according an analysis by Arbor’s researchers.
That means the majority of affected machines are now running Windows 7, with Windows XP running at about 45% of the number infected.
Windows XP has been a major source of infections, according the analysis.
About 70% of Windows XP machines are running Windows XP, and it is also the dominant operating system, according Arbor Networks findings.
Windows 7 is also a significant factor in the rise in infected machines, according its researchers.
According to Arbor Networks, the number was more than two times that of Windows 7 in August 2015.
“It is no longer surprising that the latest numbers show a dramatic rise in the number and severity of infections in the past few weeks,” said Robyn Williams, Arbor’s chief research officer, in a statement.
In addition, the report also shows a significant increase in the use of malware in the wild, which is not surprising given the recent spate of attacks on computer systems.
The majority of the infected computers are connected to the Internet and their use of social engineering tools, including phishing and botnets, was a major factor in getting infected.
“This is what is driving the rise of infections,” Williams said.
She said that the use and popularity of social media tools is also likely a factor.
A phishing attack is when someone masquerades as someone else and sends you a link to malicious sites.
Researchers also noted that Windows XP has had an increase in malware, which they call “infection trojans” and are often used to carry out attacks on vulnerable devices.
