Apple's Mac computers have long held
the reputation of being resistant to the plague of computer viruses that are
constantly bombarding PCs. While some believe it's because the Mac Operating
System is simply more secure, the real reason is that hackers have simply
preferred to go after the most widely used platform, and that's Windows. Now
with Macs gaining market share, viruses and malware affecting Apple computers
are on the rise.
Types of
Viruses
Several types of viruses can infect a Mac
computer. Viruses that exploit security flaws in Microsoft Office can also
infect Mac when the programs are used on those machines. Browser plug-ins for
viewing animated Flash and PDF files can also harbor potential dangers, as can
Java vulnerabilities. Downloading infected files that contain trojan horses,
spyware and worms from torrent, pirated software, game or adult websites can
also infect Macs.Protection
Several companies make virus software to protect
Mac computers. Major security companies like Symantec, McAfee, and Intego all
make products aimed at protecting Macs from viruses. The programs can be bought
retail or downloaded directly from their company websites. If you are already
infected with a virus, they also offer virus-removal tools independently of the
software package.
Prevention
The best way to prevent your computer from being
hit by a virus is to use common sense and caution. Do not visit websites that
you do not know are secure. Never open attachments in email without knowing who
they are from and running the file through a virus scanner with the most up-to-date
virus definitions. Download security updates for your operating system and
Internet browser on a regular basis and do not download files from torrent
sites or unofficial websites.
Considerations
Whether it's Windows or Mac, installing and
running anti-virus software isn't always problem-free. There have been cases
where anti-virus software has caused problems on the Mac OS, although the
software companies have been quick to issue patches to correct the issues. Some
of these problems have created more vulnerability than before installation.
Still, the main problems remain the same on both platforms, decrease in system
performance and false positive and negative results. Especially with Mac
viruses on the rise, you'll likely be better off installing protection than
going without it, especially if you spend a lot of time online.
Freeware and Shareware
If you prefer not to purchase anti-virus software
from a company like Symantec or McAfee, there are several freeware and
shareware options for you to try. ClamXav is the most popular free virus
scanner and iAntiVirus offers both free and paid virus scanners. Leopard Cache Cleaner
is shareware that provides low-cost virus protection for downloaded files. See
Resources for even more options.
