Anti-virus software usage in Japan


Do you use anti-virus software at home? graph of japanese statisticsI run anti-virus software at home, and at work of course, but there always is the worry that it’s chewing up system resources – at work a full disk scan starts at noon on Wednesdays and takes around two hours to process my desktop, rendering most other tasks pretty much unusable – but better safe than sorry, which is, I suppose, how TrendMicro and the rest make their money. To find out what the average Japanese person uses at home, reported on a survey conducted by JR Tokai Express Research Inc into anti-virus software.


On the 19th of March 2008 331 members of the JR Tokai Express Research online monitor group employed in either the private or public sector completed a private internet-based questionnaire. 83.7% of the sample was male, 10.6% in their twenties, 38.4% in their thirties, 35.3% in their forties, 12.7% in their fifties, and 3.0% in their sixties.

For free software, the best virus protection is probably AVG Anti-Virus, which I recommend should be used in conjunction with a spyware detector, with SpyBot Search and Destroy being the one I employ on a regular basis.
