Panda Cloud Antivirus
If you think setting up antivirus software should be as simple as possible, Panda Cloud Antivirus 1.5 is for you. Panda stops malware well, and its extremely easy-to-use interface is great for those people who don't want to tweak all sorts of settings.
In the testing for PCWorld's April 2012 feature "Free Antivirus You Can Trust," Panda blocked 85.7 percent of new malware, the same score as top pick AVG Anti-Virus Free Edition. And the Panda freebie outperformed AVG in the malware zoo test by detecting 99.94 percent of the samples.
Panda did only a so-so job at cleaning up infections. It detected all active infections on our test system, and disabled 87 percent of them, about average on this test. It completely removed infections 60 percent of the time, also about average.
Panda's program was far from speedy in some tests. It slowed the copying of files over the network considerably, and its scan speeds were among the slowest we saw: It completed the on-demand test in 6 minutes, 10 seconds, and in the on-access scan test it took 7 minutes, 25 seconds.
If you value simplicity over speed, however, Panda Cloud Antivirus, given its success in detecting malware, makes a good choice.
