    Disable Avast during the update process..... That's what I did. Ended up switching back to Panda Cloud afterwards though since Avast still has insanely high performance impact.

    Compared to what?, AVG and Norton are far far worse perfomance hit imo. I switch from AVG to Avast due simply to performance hit from real time monitors maybe i check out panda cloud. if it lighter and faster just as good

    Norton has had negligible performance impact since 2008. Avast has always had a severe impact on system performance. I run Panda Cloud on the system in my sig, an IB Celeron laptop and an Atom based tablet. None of them show any performance impact from Panda Cloud. The system in my sig, running Panda Cloud, is at 1min from power on to "ready to use". With Avast, it's almost 2 minutes...

    Open Chrome went from 10 seconds to almost 30 seconds. Launching "Microsoft Solitaire Collection" went from 30 seconds to almost 2 minutes. Time from right click until menu went from 2-3 seconds to almost 10 seconds. Right click on the start flag went from 5 seconds to display the menu to around 15 seconds. Perceived system response in general is extremely sluggish.

    I've been using Avast on and off for 12 years. I'm far from being biased against it. I'd have no qualms at all with buying the 5 licenses I need, if they could get system performance impact under control. When I was selling computers, I installed Avast free on every computer I sold. I stopped doing so because customers were removing it due to the performance impact. BUT, that has nothing to do with this thread.


    Back on Topic:
    For those running Avast on Win8.x, disable it to download and install KB3000850. Actually disable it. Don't just select the option to disable for 30 minutes or until Restart. Disable it completely until the update is done installing. Once you're back into Windows, you can re-enable Avast with no issues.

    Brick - device which does not function and its operation cannot be recovered.
    Would not be 1st time when W8.1 update causes compatibility problems, but calling it "Bricking"?

    Agree :)

    Bricking can be used when the boot cannot be done anymore, as on a phone, but exept if bios of the mother board is touched, it cannot applie to PC as you can boot on another media, repair and boot normal in the most critic case.

    it's just "OS ****ed :bang:" lol :pc1: wich is way less hard to repair.

    Common sense > Any AV software ever produced.

    AV companies want you to believe that the internet is such a dangerous place but it really isn't. They are just trying to justify the existence of their snake oil grade software. Malware has ceased being an issue when M$ got their **** together and released windows 7.

    Win 8.1 has built in antivirus software. It works out of the box after Windows is installed...

    No, windows security essentials only protects you from the weakest forms of malware, generally those that attempt to auto-install themselves whenever you get a file from a website. A targetted attack will be pretty much ignored. Take the following situation: you have a chat application. What if the chat application can take windows powershell commands and pass it to the target? It is not hard to embed something like this into any socket-based program you create. But it's extremely powerful.

    The only way you can prevent such attacks is by behavior analysis, like many av software have. There's no way in hell windows is going to reject that piece of software. And from my own personal conclusions by testing 'funny' software that I created, avast and bitdefender seem to understand when some software is malicious better than their competition.
    And funny part is you don't even need elevated permissions for most dangerous tasks.

    Antiviruses are for dumb users, there are better way of protection. Avast,AVG,Avira, etc. are **** antiviruses if u get a bad virus it will evenetually kill these antiviruses...

    I've been using 3rd party AV for so many years back in the day.
    for last 8 ~ 10 years, I install every 6 months free portable nod32. Scan once everything an uninstall as it finds nothing. same goes for other AVs.
    I have no use for real time behavioral analysis, I have use for low latency and high performance instead.

    I have AVG on my computer, but it's only active during virus scans and when I feel there is a file that's infected.

    What people don't realize about virus scanners is unlike Windows built in "protection", scanners like Avast or AVG keep an updated database. So even if there is a new threat out there, it's already flagged and taken care of.

    Besides, I have more than enough memory for it to cause a performance hit.

    I disagree. NIS was definitely heavier than Avast the last time I used it, which was last year. But maybe it's different if you're not using a SSD as a boot drive.

    Antiviruses are for users who have little knowledge about OS. People who can't find or identify malicious software. That has nothing to do with dumbness. But i agree about last part of your message. Medium to high threat software kills those antiviruses easily.

    It's really strange to see, that Moderator of this forum uses antivirus. Guru3D moderators should have knowledge to identify malicious software themselves. (Just my opinion)

    ^^ AVs are for people with sense

    It's not only malicious sites and downloads that can infect you - but if you were a user with a bit of knowledge, you would already know that
