How do i know if my pc is infected by a backdoor virus?

how do i know if my pc is infected by a backdoor virus?.... there was a window, which said that i won something.... the only button was the "ok" button, to go on.....there was no red X on the upper side left and i could not even close safari..... so i said "ok" and then I couldnt use safari anymore, until i started the computer again(doing it usually didn´t workd, so i had to shut it down just holding the start button)....now i´m scared i could have a backdoor on my pc now..... what can I do?... or how do I know if my pc is infected or not?
please help!!

You can't get a virus merely by loading a web page. As long as you didn't enter any personal information or open any files downloaded from that site, you're safe.
Quit Safari (by force if necessary.) Relaunch it by holding down the shift key and clicking its icon in the Dock. That will stop the page from reloading automatically. Select Safari ▹ Preferences ▹ Privacy ▹ Remove all website data to get rid of any cookies or other data left by the server. Open your Downloads folder and delete anything you don't recognize.

How do you know when your MacBook is infected?

Hey All. Well my question is how do you know when your MacBook is infected with a virus? I came off windows and i have norton antivirus so i have something to tell me there. But on the Mac OS you rarely get viruses and i dont have a anitvirus program, so how do you know when you have one? And what does it do?
Thanks!

Since no ones got one that I know of it is hard to say. I figure that when the day comes that someone writes a Mac virus you will know real quick what happens. If your concerned you could use ClamXav. I use it if I download something for my wife's PC but have never found anything yet.

How do I know if my ipad is infected?

How do I know if my ipad is infected?

No need to be worried. There are no viruses that can affect the iPad.
99.9% of viruses only affect Windows computers. As your iPad does not use Windows it will not be affected.

HT5228 How do I know if my mac is infected?

I am new to mac and just saw media reports about 600K infected macs. How do I know if mine is infected?

Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
Step 1
Copy or drag — do not type — the line below into the Terminal window, then press return:
launchctl getenv DYLD_INSERT_LIBRARIES
Post the lines of output,if any, that appear below what you just entered (the text, please, not a screenshot.)
Step 2
Repeat with this line (triple-click anywhere in it to select the whole line):
find /Applications /System/Library/CoreServices -type d -name *.app -exec defaults read {}/Contents/Info LSEnvironment \; 2> /dev/null | grep DYLD_INSERT_LIBRARIES
If you get no output from either step, you're not infected with any variant of Flashback that I know of.

HT3771 How do I know my new apple mac protected against trojans and viruses?

Is my new mac ok to survive a trojan like the new internet banking one?

There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac will NOT be infected by a virus, it may have other security-related problem, but more likely a technical problem unrelated to any malware threat.
You may find this User Tip on Viruses, Trojan Detection and Removal, as well as general Internet Security and Privacy, useful: The User Tip seeks to offer guidance on the main security threats and how to avoid them.

When I login I get a message "aosnotifyd wants to use your confidential information stored in "my name" in your keychain." How do I know if it is safe to allow this? Can anyone advise please?

Every time I login I get the message "aosnotifyd wants to use your confidential information stored in "my name" in your keychain." How do I know if it is safe to allow this? Can anyone advise please?

My immediate reaction is to deny.
Have you downloaded or installed any application that may relate to the abbreviation AOS? It may not necessarily be the application's name, could be the developer or distributor.
As it's occuring at log-in, go to System Preferences > Accounts > your account > Login Items and look for a related item. If there's one there, right-click (or ctrl click) on it and select Reveal in Finder. That will show you where the originator of the item is on your system and should give you more of a clue as to what it is.
I'd remove the item from login items anyway (highlight and click the minus sign at the bottom of the window). There shouldn't be anything trying to use your keychain info to notify anyone.

How do I know external hard drive is working?

Sorry for the simplistic nature of the questions but here goes:
Purchased a Toshiba external hard drive - plugged it in and Time Machine asked a few questions and soon it asked if I wanted to back up my internal hard drive.
After 40 plus minutes the task was completed - it stopped doing whatever it was doing - that much I'm certain.
How do I know the Toshiba is continuing to back up material? The light on the Toshiba is 'on' at times and 'off' on other times - so it's backing material up when the light is on??? Automatically, on its own?
Time Machine and/or the Toshiba do not appear to have any schedule for routine back-up (such as one would find on an anti-virus application), is there a way to schedule a backup?
Under Time Machine preferences it shows the Toshiba as the external disk. Plus I just noticed that it states the next back up will be 8:34 am today - 22 minutes from right now. What an odd time and it isn't a time I selected, at least I don't think so!
How do I access the Toshiba to see what, if anything, it has backed up?
Finally, assuming the external has backed up all the important data and should my (brand new - but that's another story) hard drive crash, how do I get the computer to ignore the damaged internal hard drive and start using the Toshiba?
As you can tell these question would be easily answered by most anyone with a modicum of computer knowledge but for me, thank goodness for Apple Discussion!
Thanks in advance.

How do I know if my MBP will benefit from heatsink paste reapplication?

Dear Mac Users
I know the theme of hot MacBook Pro's has been done to death, but I would like to add my two pennyworth with respect to the specific question: How do I know if my MBP will benefit from reapplication of the heatsink compound? I have trawled numerous very long threads here and not found a satisfactory answer. The reapplication of the heatsink paste is a bit of a schlep and not without some risk of breaking it, so it would be good to know if the benefit is worth the risk.
One common question is: "Are my MBP temperatures unusual?". A useful mac temperature database can be found at the following link:
http://www.intelmactemp.com/list
Consulting this list should set some parameter space for many users - there does seem to be considerable variability - suggesting highly variable quality of heat sink paste application by Apple. In my particular case I have an early 2011 MBP (i7, quad core, 2.2GHz). This certainly ran very hot. I even had a burn on my thigh from it, which took a while to heal. I know, they are notebooks, not laptops, but still . . . . To put very hot into perspective, the CPU was sitting at over 60C at idle, and whole case would be hot to the touch, such that resting your hands on it was uncomfortable. And yes, the computer was idling, there were no rogue processes chewing up cycles. At full load, the CPU would run at 90C and the whole thing would get very hot. I avoided running major projects or rendering jobs on it to preserve it from heat fatigue - the warranty is now up.
My first attempt at reducing the temperatures, was to clean it. The clue was in the USB/Firewire etc ports. All were very fluffy, which suggested that there was a lot of crud in the heatsink fins. Fixing this was simple; adopt anti-static precautions; remove the back panel; blow air into the exhaust vents at the base of the screen. Numerous large fluff bunnies popped out of the fans and elsewhere. Alternatively, you can unscrew the two fans and partially lift them out (without removing the power cables to the motherboard). Major fluff on the heatsink fins can then be tweezered out, prior to blowing it through, to ensure all debris is removed. I did this subsequently on my Core 2 Duo MBP. After defluffing the idle i7 CPU temperatures dropped from 60C to 43C, but perhaps of more importance was that the whole case was much cooler and the keyboard temperature was close to ambient - much nicer to use.
So that fixed the major heat problem. However, the question remained, would I see any further improvements by stripping the thing down and reapplying the heatsink paste? What I was looking for in this forum was a rule of thumb based on temperature measurements to help me make an informed decision on whether to strip the thing down. As my machine was out of warranty, I wasn't worried about voiding that. Also, where I am there is zero support (Africa), so Genius Bar or similar was not an option. But jiggering a 14month (very expensive) laptop was not something I wanted to do for thrills. The data in many of the posts did not provide any answers. In the end I made some measurements and decided to do the fix. The step by step instructions I followed were very clear and can be found for many Macs/models at:
http://www.ifixit.com/Device/Mac
This guide made life a lot less stressful, as pulling a connector the wrong way could trash the motherboard, and those connectors are so very tiny and fragile. It is very important to take it slow and follow each step to the letter (and not skip steps inadvertently). My before and after heatsink paste fix temperature data are shown below. The idle temps are improved, while the full load temps look like a marginal improvement. However, CPU temperature is not the only story. Certainly after the fix, the whole case is generally cooler, so the heat extraction system is working better. Also, the CPU before and after temps are quite similar at full load, but that assumes the CPU is running at the same power. I do not know enough about the i7 architecture to say if the before speed was being limited by heat, while in the after case the turbo-boost was able to run out to the maximum. Unfortunately, I didn't do any CPU performance tests. So, based on temperatures alone, it looks like a marginal improvement, but it is certainly making a difference to case temperatures.
Note all temperatures were measured at an ambient temperature of 20C on a flat, hard surface using Marcel Bresink's Temperature Monitor. Fan speed was measured using the Fan Control software - set to allow firmware control at idle.

Back to my original question: How do I know if my MBP will benefit from reapplication of the heatsink compound? I think temperatures alone will not give a good answer - mainly because the CPU probably has variable output - due to turbo boost. One thing I did notice is that the temperature response of the CPU when it gets switched to full load, does vary according to the quality of the heatsink paste. With the original Apple paste, when I switched the CPU to full load (from idle) the temperature of the CPU went up to its maximum almost instantaneously and stayed at that level ie the graph of temperature vs time was a step function. This suggests that the CPU may be controlling the temperature by throttling itself. Otherwise, as the heatsink warmed up, the CPU should also rise in temperature - mine stayed bang on 90C and fluctuated only by a degree either side. After application of heat sink paste, the CPU has a much larger effective thermal mass and consequently heats up much more slowly. Turning the CPU up to maximum from idle resulted in the temperature climbing to a maximum over about 3-4s. After peaking at around 92C it dropped back as the fans kicked in, to around 86C.
So perhaps one way of assessing the quality of your heatsink paste is to ramp the CPU to maximum from idle and look at the shape of the temperature profile. A step function suggests a lousy job and benefit may be had from reapplication. A more gently sloping profile, followed by a dip due to the fans kicking in, may suggest you are in good shape. Obviously, this presupposes that your Mac temperatures are not insanely hot to start with (i.e. high 90sC+). In which case, if defluffing doesn't do the job, then new heatsink paste is almost certainly required.

I'm sorry but this is too funny to pass up.

Adobe Cloud has 2 different Muse programs.... how do I know which one is the newer better version?

So I am new to Muse, and my Adobe Cloud has 2 different programs from Muse... how do I know which one is the newer better version?
One Must program (Muse CC 2014.2) has a black background when working on it... it looks like other Adobe programs such as Photoshop.
The other one is light color (Muse CC) very similar to the black color Muse on functions.....
One of the difference I notice is that the light color Muse has a few widgets in the library, while the black background Muse seems to have an empty library
So... why are there 2 different Muse programs in my Adobe Cloud?

Hi
The latest version of Muse is 2014.2, so you need to uninstall another version of Muse manually.
regarding the items in Library, you can add items in your library manually, as shown in this article

How do I know if my iphone has successfully been backed up to my iTunes? I plugged it in and it said it backed up and I did a sync, but when I am looking through the summary page and I am not sure that all of my data got backed up. Please help!!

I have never backed up my iphone to my itunes because I always used the cloud. However, a few months ago, my wifi disk in my phone burned out so the Apple Store told me to back up everything to my itunes. I am going today to get the iphone 6 so I connected my phone (iphone 4S) to my itunes and I backed up and synced. However, when I look throughout the summary page and click in different areas (Photos, Movies), I don't see any of my data -- it is still asking me to Sync from iPhoto or to sync from another location. By backing up & syncing my phone, did all of my data get saved? Or do I still need to do more steps?
Sorry for the long winded question, I am just so nervous to get a new phone and plug it in to be restored and not have any of my pictures, videos or contacts, etc. Any help would be so so appreciated!

Thank you again for all of your help!! I really appreciate it!
I think I am following -- I was able to upload to my iPhoto and all photos and videos are there that is a plus! I tried to create an Event in my iPhoto and put all of my photos in that event but for some reason, now my iTunes it not recognizing that Event in my iPhoto. It is not allowing me to import just that event at the moment but I may be doing something wrong. At least all of my pics and vids are in iPhoto so that is a plus and I know they are at least saved somewhere. Just for some reason, my iTunes it not locating the event that I created with only those photos.
Thank you for letting me know about my contacts! How do I know if I have the contacts app?
Also, I had no clue that my iCloud could be backed up via cellular data! However, is this a new feature with the most updated iOS?? Unforutnatly I am like 2 iOS updates behind because I don't have enough storage on my phone. I still get the notification that my phone needs to be plugged in and connected to wifi in order to back up to the cloud :-(
How can I sync using USB? Right now when i click on the info tab for my iPhone in my iTunes this is the answer that I get -- I am a little unclear as to what it means.
Sync Contacts:
Your contacts are being synced with you iPhone over the air from iCloud. Over-the-air sync settings can be changed on you iPhone

Since you can see it in your device list it must have Find My Mac activated, but you're going to have to wait for them to take it online in order to either locate, lock or wipe it. Until it goes online you can't do anything. http://www.apple.com/support/icloud/find-my-device/
