Avast Free is supposedly the most popular software, taking 11.45% of the pie. Avira AntiVir Personal follows with 9.19%, AVG Free has 8.6%, and Microsoft Security Essentials has carved out a handsome 7.48% since debuting late last year. Below the freebies is Avast (paid) with 5.4%, Kaspersky had 4.48%, Norton at 4.24%, and ESET NOD32 claimed 3.84%.
OPSWAT combined different version numbers for each application, but most vendors have a few separate products, which makes the antivirus software chart a bit confusing. That said, things don't change much when you look at vendors. Avast leads with 19.14%, Avira has 11.39%, Symantec takes 10.06%, Microsoft claims 9.29%, while AVG is just below that with 9%.
The research firm also graphed the location of antivirus vendors. Apparently, 52% of those in the study are European, including Avast, Avira, AVG, ESET, Panda, BitDefender, G Data and Sophos. Meanwhile, 31% are located in the US, including Symantec, Microsoft, McAfee, PC Tools and Sunbelt. Numbers aside, what's your preferred antivirus and why?
