This is the software publisher’s description.

With PC Tools AntiVirus you are protected against the most nefarious cyber-threats attempting to gain access to your PC and personal information. Going online without protection against the latest fast-spreading virus and worms, such as Netsky, Mytob and MyDoom, can result in infections within minutes.

Once infected, the virus 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 PC, use it to launch attacks against other computers and websites or to send mass SPAM email.

That’s why PC Tools AntiVirus provides world-leading protection, with rapid database updates, OnGuard real-time protection and comprehensive system scanning to ensure your system remains safe and virus free. PC Tools products are trusted and used by millions of people everyday to protect their home and business computers against online threats.

Note that this is the free version of PC Tools AntiVirus. It requires a manual update to receive virus definitions and more.
