The urban legend around Macs is that viruses don’t attack them. This may have been true in the past. However, in recent times, the threat threshold has changed. Macs aren’t free from malware threats. This is why it is advisable to have an antivirus for Macs. Such an antivirus can protect you against the following threats:
First, we have Trojans. A Trojan is a piece of software that looks legitimate but is harmful. People are often tricked into running Trojans when they download Internet files or email attachments. Once a Trojan gets installed on your Mac, it can delete files, steal your data, crash your system, download more viruses or create a backdoor that enables a hacker to have access to your system. Mac antivirus software can protect you against Trojans. Another threat is worms. A worm is a stand-alone program that can replicate itself. Unlike viruses, worms don’t need to attach themselves to another program. They can run on their own. Once a worm attacks a system, it begins sending copies of itself to other computers within the network. As it copies itself, it usually deletes important files. Unless you get a Mac antivirus to stop its action, a worm can “eat up” your system files, and cause your computer to crash. Worms can also install backdoors that give hackers remote access to your computer. In addition to this, a bot is a program that “recruits” your computer for some nefarious purpose. Once a bot is installed on your computer, it enables someone else to have control over it. In most cases, bots are used for creating a botnet i.e. a network of computers that are used for Denial-of-Service attacks. Any decent antivirus for Mac computers can help you to root out any bots in your system. Finally, Ransomware is malicious software that is created to lock you out of your system. Once it takes over your computer, it changes the log in details and effectively locks you out. The unsavory people who sent it usually ask you to pay money if you want access to your Mac. If you refuse, they can wipe out all your data.
Other common threats include spyware, adware, rootkits, and keyloggers. The bottom line is that the threat threshold faced by Macs from malware is ever increasing. This is why you need a good antivirus for Macs http://www.antivirusmacapp.com/ today and start protecting your computer.
