With PC Tools iAntiVirus you are protected against the most nefarious
cyber-threats attempting to gain access to your Mac and personal information.
Once your computer has been infected, a virus or worm will usually attempt to
spread itself to your friends, family and associates by accessing your email
contacts and networked PCs. The infection may also allow hackers to access files
on your Mac, use it to launch attacks against other computers and websites or to
send mass SPAM email.
PC Tools iAntiVirus provides real-time protection and comprehensive system
scanning to ensure your Mac remains safe and virus free.
The iAntiVirus database has been designed from the ground up to detect and
remove Mac specific threats. This enables a high level of protection whilst
keeping memory footprint and resource usage at a minimum. The iAntiVirus
database is not cluttered with signatures for Windows specific threats which
your Mac is immune against.
iAntiVirus has been designed with the user in mind. The user interface is
purely functional, making it simple to scan for, remove and manage infections.
