This isn't a virus.
On a site note: Windows computers have always been more likely to get a virus as they have always been more popular / readily available. However in recent years as apple has gained popularity apple no longer claim there virus free but because there's so many more PC's in the world than Mac's then yes hackers etc have always targeted pc's over macs.
Plus IIRC internet explorer had a SSL exploit for around 3 years without being fixed...
