    Is this website safe and well known?

    It offers a free scan. But is it safe to install their activex that's needed for the scan?

    I used the online scanner, but Precx installed some .exe file on my laptop which now permanently runs in RAM.

    Anyone know why?

    Their free scan isn't an Active-X browser based scan, but instead their "Prevx CSI" product in scan-only mode. This means if their scan found anything nasty, it could be easily upgraded it in order to cleanup without having to download and scan with a further program.

    Ok thanks. I uninstalled the file anyway.

    Prevx is a safe and reputable security software company. But their main subscription product for home users 'Prevx 2' has fallen badly in to disrepute in recent months because of truly horrendous 'false positives'. So bad that on WinXP and Vista it was marking (and blocking) the update and/or install of so many standard programs that, for many users, it froze their systems.

    Many of us uninstalled the program even though we still had months left on a paid subscription.

    Also, you will find their 'Independent' support forum over at CastleCops is like a graveyard. None of the 'official' Prevx people have posted in it for months - and virtually no one else.

    Bottom line is their home products are not worth paying any money for at all.

    Jep still have a license for it and will never recommend anyone using any of their products.

    Hi Marco, hope you enjoyed your [holiday ?].

    A question, when P3 is released where will it be announced first. On the Prevx site or here?
    And also, I'm getting restless :shifty: :D

    Well, probably not only... ;) Anyway, the amount of FPs has been obnoxious, really unusable.

    B****cks. I've been using it since Prevx 2.0 came out and had hardly any FP's and when I have they have been fixed in double quick time. Just go and have a look at the other forums-Eset, Kaspersky, AVG, you name it, they all have FP's and a damn site more than Prevx. And some of them take days or even weeks to sort them out.

    Rant over

    PrevX does have a lot of false positives. I made a test now.. Made a C++ program that displayed "Hello world". I packed it using PeCompact, Uploaded to VT and PrevX detected it as suspicious.

    Hello :)

    Thank you :) Yeah, indeed everything has gone quite well.

    We'll announce it on our website, but I'm quite sure some rumors will be posted on the forum too, even because we're going to be having a beta program and I'm sure everyone here will hear about it :)

    Kind regards,

    Zillions of false positives?

    Everytime you find a false positive you can report it so that you help us to improve the software. The best software is the one where users help developers reporting them all bugs or every kind of problem they have had. It should be the best thing to do, shouldn't it?

    Thank you

    You need a different place for your forum. Nowadays CastleCops (CC) is unavailable a lot, due to systemic problems. Even when CC is available, it is verrrry slow. Also, Prevx forum at CC is largely dried up. Slow-or-no replies by Prevx personnel. Ditto with email requests. If that is Prevx's idea of support, NO THANKS!

    Let's analyze the word 'suspicious' = inclined to doubt or mistrust

    That doesn't mean that is forsure malware. Is this a false positive? No, it isn't. Prevx is just saying that looking at some characteristics, that file could be suspicious and it need an in-depth analysis.

    It's not saying that is a malware, not at all.

    We're looking into forum options - Castlecops really has been bad recently, but it does look like its getting better.
    We're still monitoring it and deciding what we should do and where we should host a forum at. We do try and respond as fast as possible with email requests.

    If something you've sent in has taken too long to be responded to, let me know and I'll escalate it. Messages get lost sometimes or assigned to the wrong departments, etc.

    Uh, Prevx is marking any packed executable as "suspicious". Useless annoying noise, stop doing such nonsense. There's nothing "suspicious" with packed execs per se, yeah indeed you need to do some real "in-depth analysis" before marking such stuff - but Prevx has been failing here for ages. :thumbd:

    Thank you for trying to teach me how our software works.

    After you've written such things, try packing your notepad.exe with UPX. It's an easy test. After that, notepad.exe is a *packed* executable.
    Wow, now Prevx should mark it as suspicious. Let's check it.

    I can make things faster:

    After that, try with regedit.exe - just another test.

    I won't reply anymore to such useless and meaningless attacks.
