Use threatfire with any other traditional antivirus program you like. Its more like an anti-spyware and anti-malware from PCTools. ThreatFire uses advanced patent-pending technology to detect signs of malicious behavior commonly used by malware threats. ThreatFire is unlike traditional antivirus products that rely on old fashioned “signature” technology and require updating every time a new threat occurs.
By constantly monitoring the activity on your PC ThreatFire’s ActiveDefense technology is able to hunt down and paralyze threats that are too new or too clever to be recognized by traditional security software.
ThreatFire employs an intelligent behavioral engine to only alert you on truly malicious behavior, because sometimes even legitimate software may look malicious. This means you are only alerted when you really need to be.
Panda Cloud Antivirus is the first free cloud-based antivirus thin-client. It consists of a lightweight antivirus agent that is connected in real-time to PandaLabs’ online Collective Intelligence servers to protect faster against the newest malware variants while barely impacting PC performance.
When you open Cloud Antivirus, the main window lets you know whether you’re safe or not with a big red or green icon. Cloud Antivirus offers a Quick Scan and a Custom scan for specific folder, files, and drives, and its exceptionally lightweight. You can opt out of contributing anonymous data to the cloud, but that also opts you out of automatic threat management.
There’s a network connection proxy option should you need it, and a reporting feature that will show you what kind of threats have been detected and removed from your computer. You can filter the report by All, Last 24 hours, Last Week, or Last Month, and there’s a Recycle Bin pane from which you can recover a false positive, if you need it. The Recycle Bin is hidden behind an obnoxious “flipping” screen that rotates when you need to access it.
It takes less than 10MB of RAM when idle, and around 60MB when scanning, which should appeal to resource-conscious Netbook users. Panda Cloud Antivirus is a decent, reasonable security choice.
