When your Mac starts behaving strangely and not as it usually does, it makes you wonder whether it might have some sort of malware on it, such as a virus, Trojan or even a type of adware. It is rare for Macs to be infected, but it is not unknown, so when my Mac started playing up, I had to check it out and downloaded ClamXav.
Could your your Mac part of a malware botnet? There is a new type of malicious software infecting Apple Macs and there is a chance that your computer could already be compromised. Reports say that only 17 - 18,000 Macs have been infected, so it is nowhere near as widespread as the Flashback worm that infected 600,000+ Macs a couple fo years ago, but it is still a worry. Here's how to check whether your Mac is OK.
Apple Macs are much less likely to be infected by malware like viruses, Trojans and other nasties than Windows computers, but they are not completely immune. There have been some well publicised virus infections in recent years and large numbers of Macs were affected by malware such as the Flashback Trojan, OSX/Crisis and others. Yes, the Mac is safer, but it is not 100% safe.
