Every time new or newly mutated piece malware bursts forth, security vendors have to boil it down into a signature that lets their antivirus products recognize and remove the threat. Given the accelerating pace of malware creation, we could be headed for a singularity—virus signature databases so big they implode into a black hole! Panda Cloud Antivirus Free Edition 1.0 (free for personal use) aims to head off disaster by pushing its malware detection activity into the cloud, eliminating the need for local signatures. Panda likes to call it "the first antivirus without an update button." It's a powerful defender against malware attacks—and it's free.
