Firefox Advises Users To Disable McAfee Plugin 213

itwbennett writes "Mozilla is advising Firefox users to disable McAfee's ScriptScan software, saying that it could cause 'stability or security problems.' ScriptScan, which ships with McAfee's VirusScan antivirus program, is designed to keep Web surfers safe by scanning for any malicious scripting code that might be running in the browser. But according to Mozilla, it has an unintended side-effect: It can cause Firefox to crash ... a lot."

    It's just as bad as norton.

      If it is as bad as Norton then uninstalling it might not be the easiest task.

    • I think that in addition to the virus detection code there's a *larger* amount of "valid paid-up subscription" nag code. The memory footprint of these things is truly stunning and kills machine's performance. Microsoft's Security Essentials used to be pretty lightweight but it's hitting middle age weight gain. At least it's not intrusive and doesn't nag you to pay up since it's free.

      In my experience it is significantly worse than Norton.

      Removal is an option for most users of a managed corporate system. My employer gives us a lot of latitude in software and I am a local administrator but there are some things that are required. An approved antivirus and HDD encryption are required. I noticed a disabled extension last night on a freshly reimaged system after installing noscript. Didn't look for plugins.
    • by Twinbee ( 767046 )

      Sometimes I think the use for such software is so you can appreciate the difference after the uninstall. I think some people become complacent at how fast their PCs are, and it's only after Norton/McAfee removal that they realise what they were missing all those years. That makes them happy - it's like a RAM or SSD upgrade for free.

    • Yes, I remove McCrappy products on sight. It's a perfect example of a cure being worse than the disease. Most trojans don't cause the nausea or problems that McCrappy does, ironically.

      Norton, on the other hand, is still living down a horrible reputation from last decade, but a modern standalone Norton Antivirus isn't that horrible anymore (I still nuke their security suites on sight). In fact Norton does have one very good program. It's their most popular one, and one of the most searched for when you start

        You should see AVG. On a Windows XP machine (won't mention whose), the kernel showed a 79MB virtual memory usage before AVG, and a 171MB usage after install and update. This is the "System" process, not all processes, mind ya. The rest took the machine well over the previously good 256MB of RAM limit. And it's DDR, not DDR2/3, so it's less expensive to get a new machine.

    • by arth1 ( 260657 )

      I am pretty sure that both McAfee and Firefox is at fault here. McAfee intercepts and alters data, and Firefox lacks proper input validation, and/or make incorrect assumptions about sequencing order.

      The combination is deadly, but I'd place more blame on Firefox than on McAfee - even though MA AV is a P.O.S. doesn't mean that FF isn't.

There is absurdly little difference between so-called "anti-virus" and desktop "internet security" products and the malware from which they are supposed to protect you. When family members ask me how I manage to happily use a 5 year-old PC that seems to be faster than their 1-2 year-old PC, I simply say "I don't have anti-virus installed"

    • by Lifyre ( 960576 )

      It also depends on what anti-virus you have installed. Some such as Norton and McAffee are worse than most viruses. Some aren't nearly as bloated and heavy and don't impart much impact on typical use.

    • It's not just about speed, though. Your 5-year-old PC may not be affected by a virus, but assuming that an infected computer runs about the same speed as an unaffected computer with full AV protection, at least the unaffected computer isn't spamming a bazillion people and giving out the user's identity for theft crimes. What's more important to you, running your computer faster or making sure your identity isn't stolen? I'm not saying that all malware is a root cause of identity theft, but if people beli

          If Free Software ever actually needs anti-virus, it will bear little resemblance to the nightmare that is AV on Windows. The only reason for the heavyweight crap is marketing bullet points.

          If your browser is isolated and your email is isolated, and you scan removable media, you won't get a virus. There's no need to hook the entire OS and scan every file as it's opened or any junk like that. There would probably be a that can do the scans for incoming attachments and downloads for any program that w

      • How often did your AV actually block a virus that would have been executed otherwise (this questions excludes emails with attachments that you would have never opened? It never has happened to me within the last 10 years. So what's the value of an AV for a user, who knows what he does?

        However, I have seen many people with AV that have been infected nevertheless (especially by downloading and installing games from dubious sources). So, what's the value of an AV, if some viruses come through?

        Note: Software

    • by Anonymous Coward

      This doesn't tell the whole story. The reason you don't have issues is the same reason you don't feel you need AV software -- you don't do stupid stuff on your computer. If users would take the time to read what comes up in their screen instead of just clicking it as quickly as they can to get rid of it and use a little common sense, nobody would need AV.

      • not entirely, there's the old buffer overflow injection attacks that let hackers run native code and other such vectors that, while rarer nowadays, don't rely on user stupidity.
        If users weren't so stupid, we'd probably see more hackers attempting to find security holes in the software.

    • Everyone here knows how it goes: I ended up being the unofficial tech support for all my friends and family. Even after swearing that I didn't know much about Windows, I accidentally helped someone clean up their PC and word got around. Anyway, I have a patented plan for fixing two-year-old computers that run like molasses: 1) uninstall Norton, McAfee, AVG, and ever other antivirus program I find; 2) install MS Security Essentials; and 3) make them buy more RAM.

  • I suggest that people switch to MSE or Avast and stay away from AVG, Norton and McAfee... If you are worried about bad sites install adblock plus and WoT (web of trust).
    • Agreed. I've never used AVG, but I had few problems with Avast, and none with MSE. Norton, OTOH, is worse than a virus, and I've heard Mcafee isn't much better.

      • AVG i've had no problems with, although for the last few months it pops up with a "AVG Security Update" that sends you to a "Look what we protected you against" page that attempts to validate it's worth. It presents it's global statistics (I think) as statistics relating to you alone. Making you think you've really, nearly, had 12,000 attacks in the last month.

  • Glad they do such great QA work, since like nobody uses FireFox.....

      • Yes, but Chrome has the "actually @^@#$ing works" feature, whereby the browser actually @^@#$ing works! Sometime around Firefox 3.6-ish, I couldn't keep more than one or two tabs open in Firefox without it crashing on me. I switched to Chrome and haven't regretted it for an instant.
        • That surprises me, I haven't had much trouble at all with Firefox in years. It seems to have more trouble on Linux, but even there it doesn't crash that often.

          I would go so far as to say 3.6-ish was a low point for Firefox. Firefox 7, if you have not tried it, is very good. I can't stand Chrome for more than 5 minutes.

  • I have the McAfee slows me down argument with IT once or twice a year, but it has been easier to move to OS X and Linux than to get McAfee off my Windows machine. What I would like is an effective way to measure the pain. IT always points out that McAfee is only taking 5% or whatever of my CPU - but I know it is I/O bound as it scans every file opened and that is not reflected in CPU use ( can I argue 1-CPU use is the right metric ?). And I suspect it scans the whole file even if the whole file is not read.

  • ScriptScan is an extension. Extensions and plugins are not the same thing.

    Plugins only run when content in a page requires the plugin to be loaded. Extensions can run whenever they want.

    A bad plugin can be killed by ending the process plugin-container.exe. A bad extension cannot, and can cause your entire browser interface to hang up, which should trigger Firefox's warning about a script that seems to be taking a long time.

Any sufficiently advanced technology is indistinguishable from a rigged demo.
