How to check the virus.

I use a MacBook Pro with OS X 10.8.5. After recently browsing some sites on Safari now I intermittently get laughter and sounds of doors opening and closing in the background for a few seconds at a time. I can't figure out why. It must be a virus, but I can't see how to remove. Should I move to El Capitan? I also get a message from some sites that Safari is supported not to stay and I would like to download another browser like Google Chrome and others. Advice please?

There is no known viruses, but you may have a malware/adware installed.

After the month next Google is more up-to-date Chrome to earlier than the Mavericks.

So I would update to El Capitan. However, yo really need more than 4 GB of memory for a performance satisfactory.

I backup data, and then do a fresh install of El Capitan of formatting the boot disk, installation of El Capitan, reinstalling the app and restore data. This way any malware/adware will not end up on the new facility.

    Hi all

    I have a Satellite A200 that my teenagers use a little, or abuse a little! Recently, it would not start up. I suspect the fan and pulled out the fan cleaned and tested the fan on a PSU, worked out well. He put it back together, ran startup repair and now the computer is operating normally. The fan is however not appear to come at all. In the Device Manager it tells me it works very well. I'm all good with the mechanical side of the House, but I'm a quamby operating system! How to check the temp CPU or fan?

    Thought that replace the fan but don't want to go that far just to get no results. Currently using the vacuum on low like an external fan and didn't want to just run the laptop with no cooling for fear of permanent damage. Although children watch movies with her on their doona may have already reached this!

    Any advice would be appreciated.

    Hey mate,

  • How to remove the virus boostspeed.exe

    How to remove the virus boostspeed.exe

    Hi Laurence,.

    As far as I KNOW, you're talking about Auslogics Bootspeed, and it is a program (even if some consider how he acts and what he does to be very similar to how the system will react as if he was infected).  For technical support, see: http://www.auslogics.com/en/support/.

    If it's this product, there seems to be any special product online removal process (but perhaps custom support can help). If it isn't this product or there is nothing like it on your system, then why do you assume that it is a virus - are guessing you or some AV programs, told you that (and if so, which) and how locate you the file name as being the problem?  What is the full path to the file (for example, C:\Program Auslogics... or other)?    What security software you have installed (all names and the exact version of each)?  What version of Windows are you using?  Indeed, please see http://support.microsoft.com/kb/555375 for ideas on other information that will help us.  The more we know, the better we can help and the more focused we can make recommendations.

    I would try the following: start by creating a system restore point, and then back up the registry as well (just to be on the safe side).

    Download the free Revo: http://www.revouninstaller.com/revo_uninstaller_free_download.html and use it in advanced mode to completely remove Auslogics Bootspeed.  If it does not work because it says it is running (which is possible if there is probably not), then start safe mode and try again to remove use Revo in Mode safe.  The chances of success are much higher now that it is not likely to be running in Mode safe.

    I hope this helps.  Please get back to us in all cases, and if it haunts you again, please answer these questions as well as what happened when you tried to remove it as suggested.  On this basis, we will have a better idea if we treat just a difficult program to remove or legitimate an infection of any (or possibly both) and take the necessary measures from there - but we need to learn more and to see if the simple answer works (or why it failed).  We desperately need your help here (provision of information) to be able to help (with recommendations and options and courses of action - or more questions).

    Thanks and good luck!

    How to remove the virus once safty scan

    Hello

    You do not say what program you use

    There should be an option in any security program you are using to delete, remove, clean or quarantine (depending on how it is formulated).

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

    If by other means, you have download and installed a fake security program, which is in fact malware. follow these steps:

    Scan of Malware in Safe Mode with network.

    http://www.bleepingcomputer.com/tutorials/how-to-start-Windows-in-safe-mode/#winxo

    Windows XP

    Using the F8 method:

    1. Restart your computer.
    2. When the machine starts first, yet once it will list usually some equipment that is installed on your machine, amount of memory, hard drives installed etc. At this point you should tap the F8 key repeatedly until you are presented with a menu of Advanced Options in Windows XP.
    3. Select the Safe Mode with networking option using the arrow keys.
    4. Then press enter on your keyboard to start safe mode.
    5. Make all the necessary tasks and when finished restart to start in normal mode.

    Once in Safe Mode with network, download and run RKill.

    RKill does NOT remove the malware; It stops the Malware process that gives you a chance to remove it with your security programs.

    http://www.bleepingcomputer.com/download/rkill/

    Then, download, install, update and scan your system with the free version of Malwarebytes AntiMalware in Mode safe mode with networking:
