Why is Prevx Not Just Another Antivirus Utility?

Thursday, May 28th, 2009

Most anti-virus utilities are powered by a large virus signature database that needs to be constantly updated to help them identify known viruses. The database keeps growing as new viruses are released at an ever-increasing rate. Also these utilities are incapable of recognizing a newly released malware since there is no match in the database.

Prevx is based on behavior-based detection as its primary concept and is very good in doing that job.

Advantages of Prevx:

* Download size of 800 KB compared to the 20 MB size of other malware utilities
* Instantaneous installation and ultra fast scan
* Cloud-based malware detection
* Highest malware blocking score

How does Prevx achieve this?

As mentioned earlier, Prevx doesn’t rely on predefined signatures, it rather looks for patterns of suspicious behavior. In addition, it takes the local age of the file and its distribution index into account, before flagging it as a malware. Newer files are under higher suspicion than a file that has been around for a while. Similarly, a widely distributed file is considered benign compared to one that is found on a handful of computers. Prevx confirms this by checking its online database.

On my computer Prevx took around 30 sec to download and performed a learning scan in 5 minutes. It will clean up low risk adware for free, but anything serious has to be cleaned up by purchasing a license key.

One drawback of Prevx is it needs to contact the database during scan and will not work in offline mode.
