Recently, it seems that Mac virus called “Flashback” is in fashion. Moreover, it seems that stronger viruses are producing by improving this virus. In additional information (March 6, 2012), the security vendor detected that it uses Twitter application for camouflaging an source of attack.
The Center has installed the anti-virus software called “Sophons Antivirus” to all PCs, but please check Recommendation of PC Security Check (Windows/Macintosh) again.
And then, if you have a PC for home, I strongly recommend the installation of an Anti-Virus software.
On April 13, 2012, Apple co. provided the special removal tool through “Software Update”. Please carry out it if you don’t recently do it.
