High danger virus

I keep losing my wireless connection.  All the other computers in my house are fine.  My macbook shows the network connection option of highdanger.  I never join it but I think it has something to do with the problem.  Has anyone encoutered this problem? 

This is not at all related to any kind of malware.
Regarding the "highdanger" wireless network, if that is showing up in the wifi menu, that is because your Mac detects a wireless network with that name nearby. There is nothing you can (or need to) do about that.
As to the network issues, wireless networking is a complex topic. There can be many possibilities. Do you only have trouble with the wireless network in your house, or do you also have trouble with wireless networks in other locations? Do you have anti-virus software, or some other kind of internet security software, installed on your Mac? Can you get a successful internet connection at home if you connect directly to the wireless router with an Ethernet cable?

  • IPOD touch problems.. pls help!!!

    My son recently received a IPOD touch for Christmas...that was the 25th, were on day 3 now of trying to hook this thing up... we can't please HELP!
    I have downloaded itunes... twice. ( uninstall, reinstalled)
    I keep getting a meesage that says " make sure your network connection is active and try again" when we try to go to the ITUNES store.
    So, I was told to drive to Mcdonalds & try and hook up their.... We were able to connect but before I could get him any games and music, I was told to create an account... I did this.... had to drive back home to activate the account... once I clicked on the link to activate from my email I received a message that says " WE COULD NOT COMPLETE YOUR ITUNES STORE REQUEST. AN UNKNOWN ERROR OCCURED (11222) THERE WAS AN ERROR IN THE ITUNES STORE. PLEASE TRY AGAIN LATER."
    I then decided to run the diagnostic in the help section of the ITUNES store.... when I did this a thing failed talking about no audio CD card found. Also, it says " SECURE LINK TO ITUNES STORE FAILED"
    I have been through all of the self help. YES... I made sure firewall has ITUNES safe to go through. I have checked marked all the proper locations.
    I called my internet provider they were of no help to me but assured me my internet connection is running fine.
    Please, help me get thing working for this little guy. PLEASE.. this has been so frustrating... He's 11 ( you can imagine his patience level) Poor kid has been doin triple on chores & straight A's to get this IPOD for x-mas & now I can't get it to work. I feel jsut horrible.
    I have a windows vista. cable connection, no wireless, had virus protection I uninstalled & my bonehead husband decided to do a system restore on my computer and now the dang virus protection is STILL on my computer and I cant uninstal it.... is THAT causing the problems?
    What? Anything?? Please help!!!

    Whoa .... first thing - do not un-install or disable virus protection! You may need to get the virus protection software to recognise your iTunes but don't un-install it!
    Next - don't bother driving to any fast-food outlet, there is life without them. (You probably need to get your store account working from a home PC before trying to get online from a public network that anyone can use!)
    As you've downloaded iTunes, that suggests your internet connection is okay (so that's exactly what your internet provider will say). The message to "make sure your network connection is active and try again" means ... make sure the firewall is allowing iTunes to get online, you say it is, so is the connection itself active? If you can get to any web site through your browser - then yes, it is.
    However, what's disturbing is the message "no audio CD card found". That seems unlikely in this day and age. Can you hear any sounds that are played on the computer, either from a web site or from a CD in the CD drive or sound file? If yes, then there is a sound card. If no, find out what this problem is.
    Got through all that?
    With iTunes running, load a CD into your computer. Does it appear in iTunes, look on the left of the iTunes window, under devices, the CD should have appeared? The song names should be listed, If not, click on *Advanced/Get CD Track Names.* Click on import CD. It should be imported to iTunes and if you have the correct settings apllied, it should be copied onto the iPod at the next Sync.
    If you manage this, try the Store, through your iTunes.
    How are you getting on?

  • I have a slow Macbook Pro

    Hi guys,
    I hope you all are doing well. I have a slow Mac, it is a 10.8.3, 2.5 Intel Core, 4GB. I bought this brand new from Apple. For the last year, this laptop has been slow to the point where I think it would be cheaper to move back to the PC and just buy a new PC every 2-3 years.
    The problems I have are the following:
    1. Web pages are loading up slow. The PC loads them faster on the same network.
         - I have tried clearing the cache and ran Onyx as well. I used Safari and Chrome
          - I also ran ClamXav and no high level virus pops up. My former boss did have a virus on his where when he would show up with his laptop at the office and      the internet would slow down. Genius bar was no help, but our help desk found a virus that was killing our bandwidth. He downloaded a lot of movies from      Bittorrent. So I was thinking I may have the same problme. But I am not sure if ClamVav is advanced enough to find these types of viruses. And Genius      Bar could not find any problem.
    2. Loading programs take a while, espcially with Word and Excel. The PC loads faster.
         - I ran the disk utilies to verify disk and the permissions
         - I even formatted the Hard Drive and reinstalled the software.
    3. Sometimes when I play a embedded video, the whole screen turns black and would take 30 second or so for the screen to reappear and continue with the clip. This problem started today.
    4. The hard disk clicks once in a while. Back when I was on the PC, this was a sign that the HD needs to be replaced
         - I would run the utility to see if the hard disk was fine. About 5 months ago it said the disk was damaged. I have been rerunning once every two months      since and so far that error has not reappeared.
    I use this laptop just to check email and surf the web. I do not do any graphic design so do not know why these simple functions are a headache. I do watch movies as well on the laptop.  I have run the Activity Monitor and nothing is really eating the the CPU and I have a decent amount of free HD space.
    I did take the laptop to Apple and they said the laptop seemed sluggish and when they did an overnight test they could not find any problems. I have has the video board changed out a few times because sometimes when I would use Safari, the screen would have a "white snow screen" for a split second from I jump from the homepage to another website. This stopped when I upgraded to the recent OS.
    Sometime the Apple tech would say that the corrupt video board would also affect the wireless connection thus the slow internet. But for this laptop, I think I changed the video board around 3 times, which is disappointing for a laptop that costs around $2,000 versus a $600 PC. I do use this laptop everday and carry it around each day until the PC laptops in the past. So it has been my workhorse for over 3+ years.
    I really do not think I need more memory since my laptop use is not demanding. I may be that the hard drive needs to be changed out or some type of virus eating up my performance. If the hard drive, I was thinking of getting a SSD.
    Any help would be appreciated.

    First, back up all data immediately, as your boot drive might be failing.
    There are a few other possible causes of generalized slow performance that you can rule out easily.
    Reset the System Management Controller.
    If you have many image or video files on the Desktop with preview icons, move them to another folder.
    If applicable, uncheck all boxes in the iCloud preference pane.
    Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    Check your keychains in Keychain Access for excessively duplicated items.
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

  • Blank home page except for toolbars; no address bar; no back or forward arrows; remove unwanted icons form toolbar

    I just installed Firefox 4.0 last night. Uninstalled and re-installed today but still have the same problems as last night. 1) I have toolbars across the top but the rest of the screen is white and empty. 2) I have no address bar. 3) I have no forward or back arrows. 4) I would like to remove undesired icons from toolbars but don't know how. I have a Windows VISTA PC and high grade virus protection.

  • Chrome Browser - with NWBC, ScreenPersonas or BI

    Due to recent high-risk viruses and malware problems with IE - we are considering switching our default browser from IE to Chrome across the organization.
    Can anyone comment on risks/issues of ScreenPersonas, NWBC or BI with Chrome browser?

    Hi Shane,
    A few things come to my mind initially.
    NWBC - for desktop can only use IE, you can't change that. The NWBC HTML version of course you can use Chrome - just check the PAM for your system for Chrome support levels
    Screen Personas uses MS Silverlight (unless you just use the HTML version)... I'm not sure how well it works with the Silverlight plugin for Chrome - it might be fine... not sure.
    Finally just also note that many of SAPs accessibility (screen reader support etc..) features aren't supported in Chrome also Adobe Interactive Forms don't work.
    Hth,

  • 'Security' shows nothing re: cookies

    I'm trying to check/remove cookies as I just had a popup that took 20 minutes before it disappeared. It was http://a.tribalfusion, which I've never seen before, so I thought I'd go in & manage cookies & to see nothing had been hacked (as though I'd be able to tell!) The popup went away after I began searching it's URL to see what/who it was.
    I've got my settings pretty secure, I think, but am unable to access cookies via Security at all; nothing in there from any available options. Am I missing something?!

    Hi Noelene,
    Glad that worked out.

    Last question: are you familiar w/this a.tribalfusion? It seems to be a 'High' danger spyware, which I've not had problems w/at all since I switched to Mac 3 1/2 yrs ago.
    I'm not familiar with it but a search on "a.tribalfusion" in Google gives a lot of hits. Seems some kind of advertising service used on some sites.
    What you can do (all in Safari, so not in System Preferences ):
    Make sure in the Safari menu the setting "Block Pop-Up Windows" is checked.
    In the Security Screen, where we've been before, make sure to accept only cookies from sites you visit.
    Remove all your cookies and restart Safari.
    If the problem persists it might be good idea to create a separate topic on "a.tribalfusion". There for sure are people around here who have encountered it and can help you better than I can.

  • Losing email? This might help

    Since installing Leopard from 10.3.9, I've experienced some of the frustrations surrounding getting my email to work. I slowly worked through all the fixes and things were just about sorted. One test I used on the previous OS was to send myself emails from my various accounts. After Leopard they got sent but just evaporated, never arriving in my inboxes. Today I went through the preference/options settings on my ISP's server. Although I've never accessed these before I found the default settings were all high for virus, SPAM etc. It was also set to autodelete for SPAM. Guess what? my own email addresses were being identified as SPAM and were being trashed at source. It could quite easily identify any sender email as SPAM, often relying on the service provider alone as the trigger. I've now reset them and as a backstop also filled in the 'allow' fields on the server for my trusted addresses. This means I can now reset the security filters to high and not lose anything. This might meet with a 'duh' or two, but hopefully helps a few not-so-techy types like me. Thanks for listening.

    I'm still happy with my AT&T iphone. Never had any dropped calls, Zero dropped calls. I do live in an area with full bars everywhere so there is no need for me to make the switch. I also like surf and talk, so that I will never give away as well. It may come handy sometimes when you really need it.

  • Move save location for all users

    Anyone know how you can move your iMovie files to a different harddrive? Something that any student can do? I want them to be able to drag them to an external drive or save to an external drive so they can work on a different computer.

    Hi
    This is a HIGH DANGER project !
    a. *NEVER !* move anything outside iMovie eg on desktop and especially the folders
    • iMovie events
    • iMovie projects
    If You move them - iMovie get's confused and very often can't be repaired.
    b. in iMovie'08 & '09 all moveing is made within program !
    c. iMovie'08 are not good at this at all - only one part can be moved and as I remember it it is iMovie Events
    that can be moved in Event browser to another hard disk.
    The Event browser window - up in right hand corner has a square when clicked toogle
    view of events as dates - or on what hard disk it is stored
    • set it to show hard disks
    • now select an event and move it to another hard disk in this Browser window.
    • follow instructions - if You want a copy or a full move
    The projects can't be moved in iMovie'08 (not important though they don't take
    so much space - just reference info as I get it)
    iMovie'09 - are far more better than iM'08 !

  • NMS 4 UBEfilter.cfg  in JES???

    We has a spam filter in Netscape messaging server 4.1, use UBEfilter.cfg, I put spammer subject key word there, filter a lot spam, drop in a center mailbox, then I clean them later.
    Wondering how to implement it in JMS 2005Q4?
    I am going to use SpamAssassin (addtag), let user to handle the spam, but for some known spam, I would like drop them in a center mailbox, then I clean them later, before deliver to user.

    here is some entry of my UBEfilter.cfg for NMS 4.1, it can not handle tone of spam, but still can kill some high risk virus/spam that we don't want to deliver to my user.
    :"noBlockIPRange" Host-From "210.50.199.*" EXIT
    :"admin" User-From "admin@*" DROP "dumpmail"
    Subject "Bank[ :]* URGENT SECURITY NOTIFICATION" DROP "dumpmail"
    Subject "Commonwealth Bank: C[lI]ient's Data Verification" DROP "dumpmail"
    Subject "^(Re: )*V[a-z]*A[a-z]*G[a-z]*R[a-z]*A$" DROP "dumpmail"
    $ANY "GLOBAL AUSTRIAN SYNDICATE" DROP "dumpmail"
    $ANY "(Microsoft Corporation)(.*)(Security)" DROP "dumpmail"
    Could you give me a sample sieve script to handle these case? Any where can I find a good tutorial for Sieve script? SpamAssassin only return score, how let it sort spam to centre mailbox, instead of user's mailbox? I guess it should be done in spamfilter1_string_action, but I don't know how:-( please give me a sample, Thanks!

  • I read an article in the paper today re the virus that locks off I-phone and I-pads, I have an iMac and an iPad 4. Is there a danger of this happening and if so how do I prevent it? Many thanks, Roger Biggin.

    I read an article in the paper today re the virus that locks off I-phone and I-pads, I have an iMac and an iPad 4. Is there a danger of this happening and if so how do I prevent it?
    Many thanks, Roger Biggin.

    You may be referring to the "Oleg Pliss" hack (not a virus), in which some people (mostly in Australia and New Zealand) have had their Apple IDs hacked and used to remotely lock their iOS devices. If that's what you read about, be sure that you are using a strong password on your Apple ID, and consider enabling two-factor authentication on your Apple ID to make it difficult or impossible for a hacker to take it away from you.
    If you live in Australia or New Zealand, it may be worthwhile to turn off Find My iPad on your iPad, at least until the cause of the problem has been determined. Of course, that reduces the protections against theft. You'd be better off to just make sure you're keeping the iPad backed up, so you can restore it if it happens to get locked.
    If this isn't the story you read about, we'll need more details about what the story said.

  • CPU become very high - OS restart automaticaly - Virus?

    i am experiencing since 3 months a problem with my cpu ...
    the use of cpu become very high suddenly and this is when i access the internet...
    the computer is just after that out off control and the OS restart automaticaly from scratch ,why is that??

    Hi Ryad,
    This behaviour soiunds very much like the Sasser worm which causes extremely high CPU usage and also causes the PC to reboot routinely.
    You will need to boot your notebook into SAFE mode and then run your anti-virus software (I would also run your Malware software as well) to try to remove the virus. However, Sasser is not that easy to remove so please also check the following URL :-

  • Comcast  Cable High Speed Service-No offered Firewall,Virus protection,etc

    I just switched to Comcast "High Speed" Cable internet service from Earthlink dial-up.Unfortunately the suite of security products offered are not Mac compatible. What are the most effective products out there for security for Mac's? Thanks
    IMac G5   Mac OS X (10.3.9)  

    Hi, garyah and ~Bee!
    I'm writing to echo Bee's words of encouragement.
    I also have Comcast + a Cisco router. As far as I'm concerned, the router's firewall is extra gravy — OS X's is fine. Enabling this firewall "built-in" to OS X 10.3.9 that ~Bee mentioned is a simple matter: System Preferences »» Sharing »» Firewall »» Start. Mac Help »» type in "firewall" and »» "sharing" will provide you with ~all you want to know. [1]
    Beyond this, imo, common-sense resistance to "social engineering" is the best protection — i.e., think before opening an email attachment or launching an .exe file from a potentially dubious source, etc...
    Security remains one of the subtle pleasures of Mac ownership. [fingers crossed!]
    Warm regards,
    Dean
    [1]   Various "Services" may need to have ports "On" in Sharing — but each port opened to enable network services is unprotected, even with the firewall running. This is good to keep in mind, too.
    Hey, ~Bee — what'd'ya mean none of Comcast's perq's are Mac-compatible? Don't Comcast Mail and "The Fan" work for you? </giggle>   While this context is handy, have you ever used their "Personal Web Page service?" My son's bugging me to put up a web page, and I'm a true neophyte...
