    I need help! My 2014 rMBP seems to have some virus/malware.. I used to run clamxav, but now it isn't free anymore. Can anyone recommend a free app, please?

    My macbook is restarting for no apparent reason.

    Please, please help!

    Thanks in advance!

    Look at the system log first. There are no true viruses in the wild for OSx.
    Also what changed before the MBP started this restarting?

    I'm sorry, but I don't know how to look at the system log?

    I was just browsing the web.

    Thanks for your help.

    Regardless of whether they're called viruses or malware, random restarts are not a typical symptom of "infection," on any OS. While it may be convenient to blame viruses, UFOs, or the devil for unexplained phenomena, chances are that there's a different, far more mundane cause.

    Computers and the software that runs on them are incredibly complex, and complex systems would be prone to inexplicable failures, even if malice and evil did not exist. There are many known issues with hardware and software that can randomly crash/restart a computer - some will keep reoccurring until the cause is located, some will happen once or twice and not return.

    System logs can be helpful in locating the issue - at the least, they'll point to the last thing that happened before the crash - maybe it caused the crash, maybe it didn't. One thing is certain about logs - it takes some experience and knowledge to understand what they say. Feel free to look at them - go into your Applications > Utilities folder, and open Console. (Hint: Console Help can be your friend)

    By all means, install an anti-malware program - just don't expect it to solve the issue. (And if the problem doesn't return, don't assume that the anti-malware program fixed it - coincidence is king!)

    Did you do the Firmware update ?

    Last week , I could not get Safari to load web pages , although FireFox would.

    For the heck of it I check to see if there were any updates , should enough there was.

    After the update , Safari was back loading pages !!

    Later :)

    Another thing you could try is to create another user and log in as them. If the problem goes away then you've narrowed down the problem somewhat - it's probably something to do with your user account. If not then you can probably discount anything to do with your user account.

    The advice to take a look at the system log immediately after one of these strange restarts is also good. If it doesn't make sense to you, you could post the last few entries before the restart and maybe some kind soul on here will take a look and interpret for you.

    Although it's not impossible, I agree with other posters that virus/malware is extremely unlikely. Not impossible, but extremely unlikely.

    Random restarts are not common with anything that is in the wild. However, when I was young and experimenting with some CMD commands and I did happen to create one that forces the computer to shutdown after a certain time limit had elapsed.

    This is the most unlikely thing in the world...especially to end up on a Mac...but I would check your start up programs and see what is going on. You could have a start up program that is not running properly.
