I have one thing thats annoying. I installed ACDSee today and had to give permission to about 40 changes. Teatimer asked once only for the app. itself. Prevx asked for every reg. change.

They explain in their website that if you're installing a 'trusted' software you should disable it... Well, makes sense: security depends on reliability, confidence, good habits, software protection... It's not a mechanical solution  8)

Thanks Technical
I didn't see that. It's actually easy enough to do. Just a right mouse click away. ;D

Everything working fine with Prevx untill now...

A little bit more information:



Prevx Home protects three main areas:

Memory Protection

Memory protection prevents against buffer overflow attacks, and because different programs behave differently, several different security settings are provided.

File System Protection

File system protection is designed to prevent attackers from accessing your computer's file system, but still allowing legitimate programs to continue normally. Attackers are prevented from installing malicious code on to your computer and stop legitimate programs from being hijacked. For example, Prevx Home will stop unauthorized modification of important system files, such as Autoexec.bat.

Registry

The registry is a key component of Windows. Making changes to the registry can allow an attacker to modify system behavior, cause programs to behave in unusual ways, not to load, allow malicious code to be automatically run, and so on. Numerous security settings are provided to protect the Registry from such unauthorized changes, but ensuring normal access by legitimate programs are not affected.

For each of these areas a number of security settings are available, and when combined, provide comprehensive protection.

Most attacks will violate multiple security settings and in more than one area. Prevx Home provides robust protection through applying multiple security settings in a layered security model. This means that if an attack is not caught by one security setting, it is caught by another.

I think the confusion is coming from the warnings Prevx gives.

It should serve as a reminder when we download a programme, how many changes it can make to the p.c. without our knowledge.

At the risk of upsetting some members who don't understand the English sense of humour ......... rtfm ......... about Prevx that is!

Be honest, how many of us get sick of the pop-up windows we get when installing programmes or on pages on the web and just take the easy route and click OK.

I have found it a very useful addition to my on-line security and have no problems with Prevx running along with Adaware Spybot Tauscan and avast!

There are many on these forums who want to know how to stop the avast virus warning they have encountered a virus. Now that is one popup box I certainly don't want to simply click OK. I want to know what is going on with my system. Surely people are not geting so many infections as to be bored with the popup? If they are than it's time to review their security proceedures.

But as someone mentioned it fires for every registry change (and there can be many) when a new program is installed. So there are times when it is recommended to disable whilst installing a trusted program.

David,
I think you used the magic phraze:

That also holds true for upgrading a trusted program. Provided the download is from a trusted source.

Well, I have had Prevx for several days now and it works just fine. I do not mind the pop up alerts it gives me as I can make several choices when they do appear according to my preferences. It does what it says it will do, co-exists with all of my other security measures without any problems. I appreciate finding out about this program and will continue to use in with my WinXp Home, SP1. Thanks again. ;D

Just a thought for any readers of this thread who still use dial-up, Prevx should notify of any changes if you inadvertantley install a premium rate dialler.  That's got to be a good thing being as how one Irish telecoms provider is blocking premium rate numbers by default since last week because of the number of customers being hit with unexpectedly high 'phone bills.

I said "should" as I can't test it as I don't have any machines using dial-up.

I installed this a couple of days ago. It seems to be working fine for me on my W98SE computer ... also using ZA4.5, Ad-aware, Spybot ... and avast!4 Home, of course.    :D

The best thing about prevx is how they managed to wrap a tiny, almost trivial set of utils to a nicely-looking package and furnished it with an aura of almightiness... :)


But it's interesting to look at, that's for sure...


BTW it keeps crashing one of my machines badly (it reboots even before the boot Windows XP logo shows). Maybe it's because it's WinXPSP2 + AMD64... Never mind. :)

I heard that Microsoft were making a SP2 for AMD 64 processors and it was comming out in october  ???
