One of the best methods of encouraging people to upgrade their computer’s security is to provide the tools for free. This security suite, PCLive Security, bundles a free antivirus product (ClamAV), a personal firewall and a popup (and adware) blocker. I haven’t had a chance to test it but it certainly looks promising.
There’s a paid version that also offers support, a hard drive maintenance module and a file optimisation module and a few other extra features. The price is US$4.95 a month, which is on par with other packages.
There’s a review here with a response from the CEO of PCLive providing a better idea of what it can do.
