Someone or some computer has been sending unwanted...

Today my friend texted me that she received a message from me. I was supposedly online while I was actually on the train where my computer was turned off and no internet connection whatsoever.
The message was:
"Hello. Register on my new erotic cam chat (link removed)
After register first 10 minutes of cam chat - FREE! (*)"
And it was sent to a bunch of people on my contact list who were probably online all the time.
I since my computer was offline, I am quite sure there is no malicious software on my computer.
I've changed my password instantly, but I am still not sure how someone could have gotten my password.
What are the next steps I should take? How I can prevent this from happening again?

yup, it's a scam promoting a possibly fake antivirus/security software. There is truly no way to someone or something to know that there are threats in your computer remotely (or at least without using certain software/apps and with your knowledge/permission).
if you haven't downloaded any stuff from that site, I think there should be nothing to worry about. But a full antivirus scan using a fully updated antivirus software is recommended as a safety net.
Finally, block the user and send a report to [email protected]

Someone has been sending random messages. ?!?

Hi there,
I'm a newbie. The reason why I joined Skype Community is because I suspect someone has been sending me fraudulent voice recordings of something to do with security.
The sender's account name is "id.5514" (without quotation marks, of course).
In the voice recording there is a male talking about something about security isn't enabled or active on my computer. It says in the recording to go to http://www.mssls.com immediately to enable security protection. (Do not try this link unless you are part of the security team as I do not know the level of authenticity this website has.)
Anyways, if you go to this website, there is nothing but a blank white page.
Could someone please verify if this is a virus, or anything else that is potentially harmful to my computer, my Skype account, or my personal details?
Thanks,
ianextreme

My computer has been infected by a Trojan Horse. It has taken over my Mac email account and began sending out malicious emails to everyone in my address book. I cleared out my MAC address book and began using my AOL email account. It took a few days and then my AOL email account was infected and has now been send out malicious email to all my contacts for over a month. It has also infected my iPhone--I am no longer able to send or receive emails on my iPhone. Also, once the Trojan Horse began using my AOL email it completely blocked me from using my MAC account by sending never ending popups asking for my email password to access my MAC email account, but it never accepts my pass word. The TH has also slowed down everything on my computer. It's like I am working on an old PC with dial up connection instead of the high speed digital connection that I have. The little color wheel spins constantly as I wait for sometimes over a minute for a page to pull up. If it pulls up at all. I have tried to use the 2 disks that came with my computer to completely remove everything on my computer and then reinstall all the programs, but I am not allowed to sweep my computer clean. I thought maybe my disks that came with my computer were defective so I called Apple and they sent me 2 new disks. I am not able able to clear my computer with the 2 new disks either. I have done this before successfully so it's not something new to me. I do remember when I believe my computer became infected: I had googled an unusual sewing term, and I was opening what appeared to be legitimate sites, when all of a sudden a pop up appeared that said that my computer had been infected. I immediately shut my computer off, but it was too late. I downloaded a virus program for Mac, and it has never found a virus or problem at all. I think it is part of this Trojan Horse, but I am unable to delete it from my computer. It refuses to uninstall. The Mac Trojan Horse is real and it is terrible. If anyone has any suggestions for me I would be very appreciative,

I have Adobe Reader X loaded on my computer. Adobe sends me automatic updates periodically. I have been told that some hackers have been sending what appears to be an Adobe update and when I select run it will load malicious software or spyware onto my computer. How would I recognize this attempt and how can I prevent it? I also have Norton protection loaded on my computer (via Comcast). I am not sure if Norton can protect me if I select run. Do you have any suggestions?

Hi peterc,
By default, Reader updates occur automatically via the Reader app itself, and this is the most secure way to receive updates. While you can choose to update manually (by choosing Help > Check for Updates), you may not always get critical updates as they're released. See Automatic updates | Acrobat, Reader. If you receive an email about needing to update Reader, you should ignore it, as that is where the malicious updates can come from. Just make sure you're letting the updates happen from within Reader, either automatically or manually.
Best,
Sara

YOUR APPLE COMPUTER HAS BEEN BLOCKED

Recently, there is a Mac system alert says that "your apple computer has been blocked". It appears every times when i use websites. Indeed, some strange ads websites show up suddenly while i am using websites. What's more, the websites always break down since the alert appears. What can i do?

You may have installed a variant of the "VSearch" ad-injection malware. Follow Apple Support's instructions to remove it.
If you have trouble following those instructions, see below.
Malware is always changing to get around the defenses against it. This procedure works as of now, as far as I know. It may not work in the future. Anyone finding this comment a few days or more after it was posted should look for a more recent discussion, or start a new one.
The VSearch malware tries to hide itself by varying the names of the files it installs. To remove it, you must first identify the naming pattern.
Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
/Library/LaunchDaemons
In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
A folder named "LaunchDaemons" may open. Look inside it for two files with names of the form
          com.something.daemon.plist
and
           com.something.helper.plist
Here something is a variable string of characters, which can be different in each case. So far it has always been a string of letters without punctuation, such as "cloud," "dot," "highway," "submarine," or "trusteddownloads." Sometimes it's a meaningless string such as "e8dec5ae7fc75c28" rather than a word. Sometimes the string is "apple," and then you must be especially careful not to delete the wrong files, because many built-in OS X files have similar names.
If you find these files, leave the LaunchDaemons folder open, and open the following folder in the same way:
/Library/LaunchAgents
In this folder, there may be a file named
          com.something.agent.plist
where the string something is the same as before.
If you feel confident that you've identified the above files, back up all data, then drag just those three files—nothing else—to the Trash. You may be prompted for your administrator login password. Close the Finder windows and restart the computer.
Don't delete the "LaunchAgents" or "LaunchDaemons" folder or anything else inside either one.
The malware is now permanently inactivated, as long as you never reinstall it. You can stop here if you like, or you can remove two remaining components for the sake of completeness.
Open this folder:
/Library/Application Support
If it has a subfolder named just
           something
where something is the same string you saw before, drag that subfolder to the Trash and close the window.
Don't delete the "Application Support" folder or anything else inside it.
Finally, in this folder:
/System/Library/Frameworks
there may an item named exactly
            v.framework
It's actually a folder, though it has a different icon than usual. This item always has the above name; it doesn't vary. Drag it to the Trash and close the window.
Don't delete the "Frameworks" folder or anything else inside it.
If you didn't find the files or you're not sure about the identification, post what you found.
If in doubt, or if you have no backups, change nothing at all.
The trouble may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
This trojan is often found on illegal websites that traffic in pirated content such as movies. 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.
Then, 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.

Help* Getting a pop up that says Your Apple computer has been blocked

My partner was using my laptop yesterday and was trying to download the NHL hockey game stream from nhl-stream.com. He tried downloading it and downloaded MacKeeper and some video player. This morning I realized what he did so I googled how to uninstall MacKeeper and did so. I was unable to find the help file to delete for MacKeeper. I also deleted the video player and everything recent from the downloads. Now I'm havinganor problems with my MacBook Pro. When I use Safari it's no longer my regular Google homepage it's search-quick.com which I cannot get rid of? (Anyone can tell me how that would be helpful)
My biggest problem is the pop up that comes up and says
*YOUR APPLE COMPUTER HAS BEEN BLOCKED*
Mac System Alert!!
System has been infected due to unexpected error! Please Contact Apple Care 1-855-680-7080 Immediately! To unblock your computer....
I Googled other pop ups like these on apple support and they says to hit Control W to close the window then change security preferences. The control W does not close the window I can only get rid of it by clicking Force Quit. Then when I reopen Safari either the Popup immediately comes or the first website i search it comes. Sometimes I also get new windows open for MacKeeper. This is very frustrating and I am still learning on how to work around my Mac. I have never found a problem with my computer before he went and downloaded the game.
IF anyone can direct me in the right direction to have this removed so it's safe again to go on my banking etc that would be great! I tried to call apple support but of course my call support has expired!

Choose Force Quit from the Apple menu, close Safari, and then launch it with the Shift key held down. If that doesn't work, temporarily disconnect the computer from the Internet.
If that message continues to appear, click here and run Adware Medic; the MacKeeper popups may also be produced by adware. You may need to use a different web browser.

HT5318 Ever since I updated what looked like iTunes 10.6.1 my computer has been corrupted with Malware, which has filled up all available space on my hard drive. What do I do to get rid of the Malware?

Ever since I updated what looked like iTunes 10.6.1 my computer has been corrupted with Malware, which has filled up all available space on my hard drive. What do I do to get rid of the Malware?

First, reboot. That will temporarily free up some space. According to Apple documentation, you need at least 9 GB free for normal operation. You also need enough space left over to allow for growth of your data.
Use a tool such as OmniDiskSweeper to explore your volume and find out what's taking up the space.
Proceed further only if the problem hasn't been solved.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To really see everything, you have to run it as root.
First, back up all data if you haven't already done so. No matter what happens, you should be able to restore your system to the state it was in at the time of that backup.
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.
After installing ODS in the Applications folder, drag or copy — do not type — the following line into the Terminal window, then press return:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
I don't recommend that you make a habit of this. Don't delete anything while running ODS as root. When you're done with it, quit it and also quit Terminal.

I have always heard that Macs are less likely to get infected with a virus. My computer has been running much slower since I installed Maverick. Just not sure what the problem might be. Is there a way for me to run a diagnosis?

I have always heard that Macs are less likely to get infected with a virus. My computer has been running much slower since I installed Maverick. Just not sure what the problem might be. Is there a way for me to run a diagnosis?

Some have found relief just by reinstalling, but it is more than likely incompatible third-party applications that slow it down.
You will have to investigate to see what it is.
Open Activity Monitor and see if anything is using a lot of CPU% or Memory. If they are, check to see if there is an update for them.
Another place to look is the Console. See if anything is logging repeating messages with throttling and/or respawn in the All Messages list.
Sometimes it is not that easy to root out the problems, but if you have anything that purported to clean, protect, optimize, maintain, or flush your system, then that is likely the cause.

Many thanks b Noir
This is a copy of ONEof the keys in the registry I changed as told by Apple support today. I also have changed others as instructed by GEAR software support to manually delete GEAR drivers (that I had installed but couldn't delete some of the others they mentioned from Windows system 32. Then some bright spark at work told me I need the Gear drivers so I downloaded the software and installed again.
Sorry, just this minute went to insert image and it is giving me a message saying this sort of content is not allowed?.
The most recent key I altered is in: HKey _local _machine. System\class - 4D36E965-E325-11CEBFC1-08002BE10318. Upper Filter data: Upper filter NTIDrvr SiRem GEARAspiWDN.
The GEARsoftware info about manually deleting GEAR drive is from:

I hope you can help

How do I know if my computer has been hacked into?

I am having two issues with my iMac. One is with my wireless -- in the past few days I've received a few times an IP address error, which seems to be solved by renewing the DHCP lease and restarting. Also, at the login screen when I restart, it takes two tries to log in -- on the first one, my password only partially registers and the screen "bounces", then the second try works. Could this mean that my computer has been compromised? We had some workmen alone in our flat while we were away recently, so there are a few people who've had access to the physical machine as well. Thanks for any help.

You have not been hacked. Something went wrong with Word and it crashed, and something must have reopened Word. (The system will usually ask if you want to reopen a crashed app... did you see such a message?) Word must have simply reopened the docs you had open when it crashed.
It's actually quite difficult to hack a Mac, and pretty much requires you to help out by opening it up for potential access by hackers.

After downloading the new OS X Yosemite my computer has been lagging, how can I fix this?

Launch the Console 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.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen. Click the Clear Display icon in the toolbar. Then take one of the actions that you're having trouble with. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Some private information, such as your name, may appear in the log. Anonymize before posting.

How can I count time that a computer has been connectted with the internet

I want to count the time which a computer has been connectted with the internet?
I had already tried several times,
one is socket,
second is Runtime.exec("ping -n 1"+ip)
I don't think they are better;
do you have another idea?

The internet is a conceptual entity not a physical entity so you are never connected to it.
As a conceptual entity the internet is represented by a cloud of computing devices (computers, gateways, routers, etc.)
Your computer connects to a another computer by being routed through various devices and then finally connecting to that remote computer.
Depending on various thing you can measure the time that you can connect to other devices by either pinging a common IP in the internet (such as yahoo.com) or by pinging the router that that represents the entry point for your cloud (such as the router/gateway of your ISP.)
If you are concerned about a particular connection, such a specific remote computer, then using a socket and sending a 'keep-alive' message and recieving the response is the best way to track that.

How to detect if my computer has been hacked

I received an "error message" today on my MacBook Pro indicating that someone else was using the same IP address as my computer on my network. A little while later a friend forwarded an email to us that looks like it cloned an email account. I'm curious if anyone knows if these events might be related, and if so, how you can check to see if your computer has been hacked? Thanks much!
Georgebob

The "same IP address" error is pretty common. It pretty much never indicates your computer has been hacked. If you have lots of devices on your local network, this can happen. I assume you're using DHCP but this depends on your router (Airport Extreme, Linksys, other?) etc. I hope your wireless network is encrypted (preferably with WPA2); if your wireless network is not encrypted then you may have 47 of your neighbors and 4 people in cars out on the street surfing **** on your Internet connection and downloading illegal material. But that's not a hacked Mac, that's just bad form on your part ;-)
As far as the forwarded email: I'm unsure what you're referring to. Looks like it cloned what email account?
At any rate, no, I don't think the events are related. Duplicate IP addresses can happen due to DHCP leases and sleeping machines and having iPhones, iPads, Apple TVs, and Macs on the same network. The machines will work around it and it's rarely a sign of being hacked if you have control over your network.

I believe my computer has been hacked.

I belong to a google group and receive emails from the group. I was told by the adminstrator (University of Illinois) that my computer was responsible for sending out spam and that I should change my password. Excatly what should I do if my computer has been hacked? I use yahoo for my email and sometimes directly from my mac. I did see that my "Console" showed up on my dashboard and several lines said "swallowed up". If anyone has an explanation as to what may have happed and how to fix it I would appreciate it.

I doubt your computer has been hacked, it's more likely that your email account has been hacked. There's big business in firstly finding email addresses and secondly cracking them, either through Windows malware, password guessing or exploits against the email provider. Change your email password, and to be sure, your Mac's password.

Someone or some computer has been sending unwanted...
