Prevx - Intrusion Prevention
« on: September 23, 2004, 11:58:37 PM »
Does anybody know about this software?

(https://www.prevx.com/)

The Home version is a freeware (https://www.prevx.com/homeoffice/prevxhome/prevxhome.htm)

They claim to be an essential complement to existing signature based Anti Virus and Personal Firewall products, the Host Intrusion Prevention capabilities of Prevx Home are the only realistic defense against the latest breed of fast moving attacks.

Within the simple yet powerful user interface of Prevx Home reside multiple layers of dynamic security settings. These enable Prevx Home to catch and stop new, never before seen attacks at many points where they may attempt to compromise your machine.


And, more than this, Prevx Home would be able to:

• Stop ‘Buffer Overflow’ attacks used by Internet worms (such as Sasser) and hackers
• Stop the installation of malicious files
• Stop malicious modification of critical files and directories
• Stop frequently used attacks on Internet Explorer
• Stop unauthorized changes to critical areas of the registry
• Stop covert modification of start-up scripts


The main reason, is because Home computer users remain vulnerable to each new (‘Zero Day’) cyber-attack during the critical period between the launch of a new attack and a “signature” update becoming available. Spyware tools only detect and clean up installed malware AFTER the infection has happened. Often threats are missed entirely by traditional security tools.

I read the same thing you did. It just sounded to good to be true so I passed it by. Sure would be nice if it turned out to be something.

It's used (pro version) by at least 1 of our police forces here in the U.K.

Here's the link

Well it's on my puter and behaves itself on SP2 and ZA and Avast.
Can't tell if it's doing anything guess I'll find that out if catches something.

Works fine for me, no outward connections.  Checks for any changes to the registry. No usage hog, all the time I'm not getting a warning I'm happy.

Teatimer does that and it's extreamly small. This is supposed to do more than just monitor the reg. for changes.

Technical, thanks for the information concerning Prevx. I have WinXp Home, SP1, Outpost 1.0, WinXp firewall activated and my system does not show any problems from having downloaded Prevx. ;D Thanks again for the  tip. :)

More info I found here:
http://www.wilderssecurity.com/showthread.php?t=47773&highlight=Prevx

Can anybody comment?

Best opinions (in my opinion  ;D):

1. There's nothing magical about Prevx, it just monitors several areas of the system that are often manipulated by malware, but does require extra user interaction when activities (often legitimate) are detected.

2. Prevx is generic detection that requires no signature updates. I would guess that is uses behaviour monitoring and some sort of heuristic anylisis to prevent malware infection. It also monitors registry activity, prevents buffer overflow attacks, and prevents dll modification. This software is ment for prevention as opposed to detection.

3. Prevx Home doesn't rely on signature-based method but detects potential attacks by their behavior so it can detect (theoretically) malware that can bypass your traditional anti-virus/anti-spyware/anti-trojan.


About being free...

4. Prevx makes their money from their corporate product and soon to be release Pro version of the home product. It's almost too good to be true, but it's true and pretty damn good.

Yeah, I know you posted about it in Wilders too...
Do you have anything negative to comment? Does it work? TeaTimer can be replaced with profit?

Technical. I also have Prevx and so far nothing negtive to say about it. Just sits in the background and does what it is suppose to do is what I have observed.
