    Admittedly I gave up adobe years ago because it always took so long to load. I went through the popular replacements and have been using Nitro for a while now. The thing is, Nitro takes as long as adobe ever did to load on my ancient XP machine but kind of like never giving up firefox because of the extensions I use, I can't give Nitro up because of its amazing editing abilities. I suppose I could try Sumatra for just quick reading and still keep Nitro in the tool box for editing. For anyone who needs a pdf tool that goes far beyond just the capability to enter text (fill forms), give Nitro a look!

    Dermot7, yesterday PrevX still flagged Sumatra as malware. I am so used to PrevX not having a clue I hardly notice any more. RJ TextEd and MyPaint got "nailed" yesterday as well. Happens on a regular basis when not using top 20 programs it seems.

    Just to clarify, as I said in post #20...for me Prevx (3.0.5.220) didn't detect Sumatra at all, even portable version. The FP came (only 1.4 portable) with Hitman Pro, and I did myself click option to report file as safe, and I found no
    detection 1/2 day later.
    FWIW, I disagree with your assertion ( imo exaggeration) that Prevx will FP to such a prolific extent nowadays...make sure heuristics not set too high, and perhaps lower a little if you use/install some more rarer applications.

    Let me put it this way. We return to PrevX when the 10 mile long thread about beta version get replaced by actual experiences with it ;) I highly expect improved ways of ignoring programs mistakes.

    No I am not doing much exaggeration but am colored by the fact I yesterday were so unlucky to install/update 3 programs in a row - ALL detected as malware by PrevX. In RJ Texted case for the xxnt time. Over the top naturally but will not say that is spectacular or I should feel haunted. You can report false positive all you like, done that ages ago. I have found "Trust Always" to be more effective.

    I did not even mention "Nirsoft" :) I can find the post from PrevX rep saying it is a bit wrong to flag him over and over. "We debate this internally" or something close to. Really? I can also show what PrevX detect as of right now or you can do it your self. Change of policy when a weather tool is considered malware I think. Have not checked latest version, doubt it has changed. Anyway I might be spoiled since used to Avast. Other AVs might be just as lazy. BitDefender can be funny I know that. Well, not my impression PrevX work tirelessly to avoid this but we will see with 4. Kind of pointless to whine about 3 but I just felt like it.

    I use same version so I guess we are talking random detection as well? Random detection of malware or FPs? Lets hope 4 comes soon, heh.

    That is fantastic.

    Here is what I see as of right now - with no manual help to PrevX. Heuristics is at medium.

    Send SumatraPDF.exe to VirusTotal or any other similar service. ;)
    BTW, did you try some on-Demand Scanners?

    Don't forget that much of PrevX strengths come from detecting malware during execution. They don't think highly of passive detection. I do believe PrevX rep even said he simply don't see the point. So nope, I trust PrevX and shall get rid of Sumatra ASAP. Not really but how I am supposed to act.

    I aim to please so did what you suggested. But is there not a forum rule about not linking to VT or similar? I don't understand why not but pretty sure I noticed that long ago. Possible misunderstanding on my part. You can test your self but result right now is 1/43 and you know which is unique.

    Many AVs with Real-Time protection have Not flagged Sumatra PDF as Malware.
    Clients, Relatives, Friends etc. use different Real-Time AVs and have no problem with Sumatra.

    I only referred to VT. I did Not post any Link.
    BTW, all online Multi-Scanners showed NO Problem, too.
    It's a False Positive.

    An AV is only trusted if it tells you how it is infected. What does it detect ?
    Traces of what ? It's extremely easy for AV software to assume anything compressed is "Infected"...

    I downloaded Prevx and scanned with it.
    In terms of Heuristics, I used Default settings and High settings.
    While scanning, I opened a couple .pdf files with Sumatra PDF.
    NOTHING was found.

    I am fully aware it is a FP - that is why I am shaking head at PrevX!

    No portable Sumatra is still not white listed. I can reproduce again and again. I don't know why you don't see it. Compressing "issues" are old as dust. Lame reason if that is the case and I kind of hope Sumatra author ignore. Find a better more intelligent AV if it really bothers you and it is not enough to whine on a security forum! Devs. should not bend over to AVs this way.

    DOSawaits, you can say that but not all will appreciate such info. They prefer to live in ignorance, probably goes for most customers of any AV. They need to be told what to do - hence the annoyance when program is totally off. Very few will be able to deal with info but guess we could imagine some sort of link to a page explaining methods to move on, how to deal with it. Then again program is in charge. Situation screams for more info as you say but difficult to put in to program without it becoming an "expert tool". Customers run away fast ;) I guess that is why most AVs do not stuff users with info on specific detections. Also the more they say/advice/promise the more you can blame them for, heh.

    Bambo, which exact version is being detected for you? I'm assuming it's 1.4 portable, but from where did you download and maybe we can compare MD5s,
    because as I said, no version of Sumatra (incl portableapps version) was detected by Prevx for me.

    I did not download anything. Ketarin did. Is set up to get link from Sumatras site or variable which is then used in download link. I guess possible he made a "silent" update to avoid compression mess - if that is the reason for detection. I shall check.

    PrevX age and popularity heuristics are both at recommended btw.
    And checked and he did not. Same file I get. Anyway as I said I am not going in to a shock seeing PrevX going crazy. Big fan of Nirsoft tools so... Sumatra guy is used to this http://forums.fofou.org/sumatrapdf/topic?id=2018337&comments=7 in blog post about 1.4 he warns about expected detections as well.

    Its detection by Prevx is an FP (as you say) so why not Allow it and then, from Detection Overrides, right click the entry for it and report it as an FP? That is how Prevx works; it relies on the user based in some measure to report FPs so that they come to their notice and they can correct their database, so that subsequantly, if they get sufficient feedback, the FP is no longer flagged/SumatraPDF is recognised as a valid/trusted application.

    I urge you to do your bit! ;)

    "sufficient" being the keyword here and why I wrongly but not 100% totally off said those not digging Top20 programs might see dark side of FPs more than others.

    I expect more manual control in version 4.

    I can help PrevX with sufficient reporting - Nirsoft programs are not malware. I can also drop it. Same result.

    Indeed...depends what you want. But you can have the best of both worlds by flagging them as false FPs and having them recorded, on your system, as Detection Overrides...so that you can then use both the Nirsoft Utilities AND Prevx.

    That is what I do and it works a treat. ;)

    For crying out loud dude. You need to read and understand words in a context, like previous posts. And stop the selective quote crap please. Right after your cut I said "Not really but what I am supposed to" making it clear even to a stone that I was joking or trying irony.

    Yes Baldrick I am aware I can tell PrevX to exclude any file. That process however becomes a bit annoying when you have to repeat it over and over - as is the case with for example RJ TextEd that gets updated often. Which is cool but not when PrevX hate it. The extra scans PrevX insist on when you do this kind of thing might be over in few minutes depending on computer but still annoying. AND I KNOW IT IS A FALSE POSITIVE That was in bold to make it easier to read and understand :) May be forum should automatically make everything bold?

    A good rule to follow when making a joke is to make it at least a teeny-tiny bit humorous. Failing that, at least add a smiley after an attempted joke/irony/satire -- *just in case*.

    IMO some folks, when realizing they posted a less-than-rational remark, will seek to cover it up by saying they were only joking.
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    NOTE: Please do not be offended by anything Bellgamin has written here because . . . I'm only joking (tee-hee).:D

    I'm with you Mr PC...time to hitch up the wagons and roll out in the other direction, methinks. ;)
