Do i have a virus? pages not loading

Hi,
my macbook keeps having these moments every once in a while in which pages just stop loading. sometimes it only happens to videos, sometimes nothing will load at all-they usually redirect me to a "no data received" page. my internet connection is fine, and nobody else in my family is having these problems on their laptops. i usually use chrome, but when this happens the same pages don't load in safari either. when i restart my computer, the problem is fixed for an hour at most and then it happens again. i used to stream movies off of a kind of sketchy website with a lot of pop-ups, so i think i may have gotten a virus from it. if it is a virus, can somebody tell me how to get rid of it? by the way, my macbook also overheats really quickly, if that helps/is related. thank you so much!

It's very unlikely that this is a malware issue, though if you downloaded and installed anything from a site providing illegal access to commercial movies, that possibility cannot be ruled out. You should download and run a scan with Sophos due to this risky behavior, though I think it would have nothing to do with solving your internet problems. If you don't want to keep anti-virus software installed (see my Mac Malware Guide for help making that decision), you can easily uninstall it after the scan.
As for the internet difficulties, what kind of wireless router are you using? Not all routers are created equal, and some can work fine with Windows machines but will be problems from Macs, due to not properly obeying wireless standards. If this is the source of the problem, you'll probably have to buy a new wireless router, though it's also possible that someone with a good knowledge of wireless networking could change the settings on your current router and fix the issue.
There could also be something wrong with your Mac that is causing the network to fail. Does this ever happen with other networks, or only with this particular one?

    I have bt inifinity 2, from my laptop and mac (with same wifi connection) webpages load no problem, from my android tablet and iphone (with same wifi connection) web pages not loading.

  • I have some web pages that loaded completely when using 3G but partially loaded using Wifi.

    I have some web pages that loaded completely when using 3G but partially loaded (only text without any images ) using Wifi. Is it a site specific issue?

    Can you rule out the NoScript extension as a cause of the issues on those sites? Even if you allow the main site to run scripts, often a website will spread its content over additional servers, so you may need to visit the "S" button menu a second or third time to get full functionality. (Over time, you'll recognize some the servers as being for ads, tracking, or sharing buttons and you can just let those parts of the page not work.)

    You can include alternative content for people who do not
    have the Flash
    player. Essentially, you write the site twice--once in HTML
    and once in
    Flash/Flex. This is one reason why people will often advise
    you not to put
    mission-critical functionality into anything that requires
    the Flash player,
    unless you're 100% certain that all of the users who need to
    see your
    content will have it.

  • Receiving pop ups to secure my files and when I log into any website i get directed to a site with a pop up regarding security.  I assume I have a virus and not sure how to fix it

    I am receiving pop ups to security sites to secure my files etc.  I assume I have a virus but not sure how to fix it.

    There is no need to download anything to solve this problem.
    You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
    Back up all data before making any changes.
    One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
    If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
    Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
    Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates (OS X 10.10 or later)
    or
              Download updates automatically (OS X 10.9 or earlier)
    if it's not already checked.

  • New to Macs..how to tell if you have a virus or not?

    I'm used to PCs which are virus ridden and sometimes you don't even know you have a virus on a PC. I was wondring if Macs have the same problem and if there is a way to tell if you have a virus or not. Anyone know?

    Jack Q,
    Like almost every operating system, OS X is vulnerable to viruses:
    It's just not as vulnerable or attacked nearly as often as, ahem, Brand X.
    What could you do if you suspect attack?
    You could report your symptoms in this forum after the fact.
    You could download a good antivirus scanner and check your machine for viruses.
    Or...
    You could take the preventive measures of:
    1. creating a separate administrator account and making the account you use a normal user account,
    2. locking down your OS X firewall,
    3. using a properly configured NAT router between your computer and the Internet,
    4. oh, and downloading and installing a good antivirus scanner (like this one),
    since Apple recommends using antivirus software, and turning on Folder Sentry.

  • Pages not loading completely

    I am seeing intermittent issues with web pages not loading completely, or taking a long time to load. Some times embedded images will not load. The page will often load, but the page loading icon in chrome will carry on spinning. 
    This is happening periodically and at various times of the day, but has been going on for a couple of weeks. The rest of the time, my broadband speeds are fine and very snappy, as normal. 
    I've restarted my router (homehub 3) several times.
    This doesn't seem to be a general speed problem.
    Using speedtest.net, i can see that my download speed is pretty consistent at just under 20mbps. 
    Using pingtest.net i see no packet loss, with good ping times.  
    Using the BT speedtest tool, my line speed to the house is around 23mbps, and my download speed is again around 20mbps.
    This is effecting all devices attached to the router, both wired and wifi... both windows PC/laptops and ipad/iphone devices. 
    I am not sure where to look next, and am kind of dreading a conversation with BT helpdesk. 
    Any ideas? 

    Thanks... That's a long thread, and I am not going to pretend to understand all of it. 
    It seems to be similar issue, but I am seeing this any webiste, including this one, not just on a handful of specific sites. 
    If I understand the thread above correctly, that issue is with BT, and was apparantly fixed, although the most recent post suggests it has not been. And that if this is the same problem, I can't do anything to fix this myself, other than raise this BT?
    Having played around a little more, I think I can see that this problem becomes more accute when i am jumping rapidly from one webpage to another in quick succession, until i get to the point where pages are just not loading anymore.

  • Pages not loading anymore. I have tried reinstalling with the same results

    I have iWork 09 on my MBP with the i7 (1 version back from the current model with the Thunderport). Software worked fine for many months but now when I try to start Pages or Keynote I get an error message saying it can not load the library. I tried to uninstall the software and reboot then reinstalled it and did an update to the app with the same results.

    Deleting the program's preference list is the #1 trouble-shooting step with any misbehaving application. Go to HD > Users > (your account) > Library > Preferences, delete the com.apple.iwork.pages.plist, empty the Trash & then restart Pages. Repeat with Numbers & Keynote. This needs to be done for each user.
    There are two things to do that solve a lot of problems with the iWork ’08 &/or ’09 apps in Snow Leopard.
    First, use the
    Mac OS 10.6.6 combo updater. This fixes a problem with fonts that is not fixed using the delta update (10.6.1 > 10.6.2). Because of font & other issues with 10.6.7, I prefer to stick with 10.6.6. You can find the 10.6.7 combo updater
    here  
    Second, make sure your iWork applications are updated. For iWork '08 that is Pages 3.0.3 & Numbers 1.0.3. For iWork '09 it's Pages 4.0.5 & Numbers 2.0.5. If you're not running the latest versions & Software Update says your software is up to date, make sure the applications are where the installer initially put them. The updaters are very picky. If the location is not where the updater is programmed to look or if the folder doesn't have the name the updater looks for, it will not work. The applications cannot be renamed or moved. They must be in the iWork '08 or iWork '09 folder in Applications. That iWork folder must be named iWork '08 or iWork '09. If it doesn't have the '08 or '09 Software Update won't find them & the updaters won't work.
    Also, when deleting iWork, you need to make sure you get all of the components.
    The files to delete are the iWork ’09 folder from the main HD > Applications; the iWork ’09 folder in HD > Library > Application Support & the individual iWork application plist files found in HD > Users > (your account) > Library > Preferences for each user.
    Yvan Koenig has written an AppleScript that removes the files. You can find it on
    his iDisk in For_iWork > iWork '09 > uninstall iWork '09.zip.

  • Secure startup home web page not loading in FF 17.0.1

    Have https://www.google.com/ set as home page.
    What I get: Go to a website
    What I do: click Bookmarks>Google url link
    Result: https://www.google.com
    Go to a website does result in Google home page loading, but it appears to be loaded locally, not via an internet connection. Have Flagfox installed as an add-on, but this does not load until I do step 2, and only then is any activity seen in the lower left hand corner of the browser as the Google page loads.
    Odd thing is, without an active internet connection, FF reports page not found error and Google is not displayed.
    Note that step 3 is missing a backslash at the end of the url, even tho it is set and entered properly in Options for General>Startup. ???
    A https connection should also be green if valid, and I am not seeing that on most https sites. GRC.com does show this green color, but that is the only one that seems to work for me. Clicking the lock icon does give me vendor ownership information; the others state 'unknown'. Example: "You are connected to mozilla.org which is run by (unknown) Verified by GeoTrust, Inc. Your connection to this website is encrypted to prevent eavesdropping.

    You only see a green color in the Site Identity Button if websites use an Extended Validation (EV) SSL Certificate and not if a Domain Validation (DV) SSL Certificate is used like this SUMO forum site is using.

    Firefox may be loading pages from the Firefox browsing cache if they aren't loaded from the internet.<br />
    You may also have other software or a router that caches some pages.
    Which security software (firewall, anti-virus) do you have?
    Did you check that your security software isn't blocking the connection?
    Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

  • Web pages not loading in Safari 7.0.5

    Hi,
    I have a MacBook Air 13 inch, running on OS X 10.9.4. I recently updated to the latest OS from my AppStore Updates settings. I have Safari 7.0.5. Since last one week I have been facing issues in loading webpages on Safari. I use a local internet provider and I use internet over a WIFI. I have a 4mbps speed from the provider.  The webpages such as Facebook and Youtube, gmail etc open up very quickly. But many other pages do not open at all. The progress bar on the internet url just completes 15-50 % and then the page doesn't load. I don't even get an error message.  Some webpages where I find issues are speediest.net.in or gmatclub.com etc. Even some of the apple discussions don't open.
    I tried the following on my system to resolve the issue
    1. DNS Prefetching: Set the DNS Prefetching to 208.67.222.222 and 208.67.220.220
    2. Tried to disable DNS Prefetching
    3. Chrome also behaves the same way
    4. Tried using Guest Login. Issue is still the same.
    5. Reset the WiFi router. Issue still the same
    To make sure there is no issue with the internet provider or WiFi router, I tried on a windows laptop and strangely everything not only works fine but also at the optimum speed.
    I am facing similar issues on the iOS device iPhone 4S.
    Can some expert kindly help me in resolving the issue. I am not sure what is causing this.. OS Upgrade or something different.
    Thanks

    From the menu bar, select
               ▹ System Preferences ▹ Network
    If the Network preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advancedbutton and select the Hardware tab. Select
              Configure: Manually
    and
              MTU: Custom
    Enter an MTU value of 1280.
    Click OK and then Apply. Test.
    You must apply the change before it takes effect.
    If the issue is resolved, experiment with higher MTU values until you find the highest one that works. The higher the MTU, the better the network interface will perform.
    If changing the MTU has no effect, restore the Configure setting to Automatically.

  • Pages not loading correctly anymore

    Running firefox 7.01 on win7 64 bit. I just recently got a popup asking me whether I would like to see additional information from when I click on a link (on my nas) or not. I selected no. However, now I do not get any confirmation dialogs anymore and some websites (which use java) seem to have stopped working. I went into settings but could find nothing that would block these particular sites are particular java options.
    How can I get this back to where it was before because now I am unable to access some sites that do not load with this setting in place anymore

    Adding Open DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security:
    If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
    208.67.222.222
    208.67.220.220
    (You can also enter them if you click on Advanced and then DNS)
    Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:

    You could also try these codes as well: 4.2.2.1 & 4.2.2.2
    If you use a Router, make sure it has the latest firmware installed.
    One reason for a slowness in page loading may be the 'DNS Pre-fetching' feature of Safari 5.x

  • Pages not loading completely or at all.

    This is a problem I've been having for weeks and weeks. Pages in Safari (or in IE or in Firefox) will not load completely or at all. For example, the apple.com homepage does not load at all and neither does ebay. However, the amazon homepage will load almost completely, but a few of the images don't appear.
    I've tried numerous ideas.
    I've run through the power cycle. (Turning my router and cable modem off, and then restarting them.)
    I've run network diagnotics.
    I've reset Safari.
    I've typed in IP addresses manually.
    We bought a new router.
    It even got down to me having to reinstall the operating system. (The computer is fairly new, so there wasn't any important information on it.)
    I tried calling my ISP, but they don't know what's wrong.
    Apple won't speak to me because my 90 days is up, and my parents won't pay $160 for the care plan.
    I'm becoming desperate at this point. I love my new iMac, but there isn't much I can do without the web.
    Oh, I also can't download updates, access the iTunes music store, or anything else that requires internet acces.
    We have three windows computers in the house that are all running fine on the WLAN.
    Any help would be GREATLY appreciated.

    Any other ideas?
    Hmm, can you try logging into another user account to see if the problem is present there as well? This will confirm where the root issue is - your user area or system wide. It sounds like it wil be system wide but best to double check.
    If you don't have another account you can use System Preferences -> Accounts -> [+] to create a test one (and [-] to remove it if needed).
    I've typed in IP addresses manually.
    Can you expand on what you mean by that? Are you referring to the DNS addresses or typing the IP address in the browsers address entry box?

    I am having trouble with certain webpages not loading correctly - even on this site. It appears incomplete. The problem is especially prevalent on Amazon. The page simply won't download fully- all the formatting if off to one side and the site is unresponsive. It is the same whether I use Safari, Firefox or Chrome. I have emptied my cache, reset cookies, but still the same. Any suggestions? I can't live without Amazon!

  • 2 pages not loading on phone and tablet

    Not all pages work on phone and tablet for my website... thegreatlifecookbook.com
    The desktop layout correctly loads on the phone and tablet, but the buy now page and the cookbook page are blank.
    No problems with the site on the computer.
    Have any ideas? Thanks so much....////Julie

    It appears you created Tablet and Phone layouts in the Muse Plan mode, but never put any content on the pages, and then published. Thus when you visit your home page on a desktop device you get the desktop layout (which appears correct) but when you visit from a phone or tablet you get the Tablet or Phone layout from the Muse plan view. Those are blank.
    You'll want to Page > Remove Alternate Layout for the Tablet and Phone layouts in Muse and re-publish, so your site is no longer re-directing to blank pages when loaded on a Tablet or Phone.
    In the future if/when you create a complete Phone or Tablet layout and re-publish, your site visitors will automatically be directed to the layout appropriate to their device (and it won't be blank since you will have created a device specific alternate layout).
