How do I know if my Mac has been infected with the virus

I recently was asked to download an Adobe Acrobat reader update but before I was made aware that the current virus was contained in a similar request, I downloaded what I assumed to be a legit update. I currently do not use my mail program on my Mac so am unaware of any spam being distributed from the computer. How can I identify if my computer has been infected with this Trojan Horse virus?

Two Helpful Links Regarding Flashback Trojan
A link to a great User Tip about the trojan: Flashback Trojan User Tip
A related link in the tip to a checker: Malware Checker Dowload Link
A Google search can reveal a variety of alternatives on how the remove the trojan should your computer get infected. This can get you started.
For now I recommend the User Tip from etressoft to detect and remove:
Checking for and removing the "Flashback" trojan

HT5228 How can I tell if my computer has been infected with the Trojan?

How can I tell if my computer has been infected with this latest Trojan (or with any Trojan)? I did install the latest update to Java when I was told by my iMac that new software was available for my computer, which was just 2 or 3 days ago (first week of April). Now it is being said that there was a Java Trojan.
Many thanks for any replies!

Log out and log back in, if you haven’t done so recently. 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
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
If you get no output from either step, you're not infected with any variant of Flashback that I know of.

Hey Cherielly,
Thanks for using Apple Support Communities.
Since you are having an issue with syncing to a different apple id. You may want to make sure you are signing in with the correct apple id.
iOS: Sign in with a different Apple ID in the iTunes Store, App Store, and iBooks Store

Is this a genuine error message 'ipad has been infected with potential virus'

II was just about to watch a film through my iPad and a new screen opened 'phone updating.com' and the message read 'Virus warning, ipad has been infected with potential virus. Click the ok button to scan your iPhone now.'
I didn't press ok and it wouldn't let me cross out so I checked and updated to the latest version (8.2) and when my ipad restarted, safari opened it on the same error page. I then went to settings and cleared my Safari history which thankfully clearly the page.
My concern now is what if I have something bad (virus?) on my iPad? Or im hoping that because I didn't click okay that all is okay again.
can anyone advise if they have come across anything similar or if I need to do something else?
MAny Thanks

Thanks, that's what I thought. Do you know if there was any other way that I could have cleared the message other than by clearing my safari history, and more importantly, as I didn't click okay, would this have stopped anything else happening to my ipad?

How can i copy a picture that has been installed with the flash player

how can i copy a picture that has been installed using the flash player

You can't. You can take a screen cap of it, but the container doesn't allow access to the individual images used in a SWF or FLV.

My internet provider informed me my Mac has been infected with a Flashback virus. How do I remove it? I have Macbook OSX 10.5.8

My internet will be cut off in 48 hours unless I remove this virus. I got an e-mail saying I was infected with this flashback virus. I called Rogers to confirm that it wasn't a phishing e-mail and it is legitimate. The only thing they did was give me numbers to a paid technical support line, I'd prefer not to call and pay. I went online and found a tutorial for removing it using Terminal, which I tried and got the error messages which apparently means I'm not affected. Help! How do I remove this virus before my internet gets cut off?
I am operating a MAC OSX 10.5.8 software system on my macbook

Maybe
F-Secure's Flashback removal tool - http://www.f-secure.com/v-descs/trojan-downloader_osx_flashback_k.shtml - supposedly also works on OSX 10.5 and earlier.
Something you should consider is upgrading to Snow Leopard since then you (for at least a few more months) will still get security updates from Apple which would cover this issue.

My mac has been updated with the latest version of Firefox but when I click on seacrh nothing happens. Please help?

I have a Macbook and as usual, I was notified of a Firefox update, which I accepted. Since uploading the new version, when I type a search into the usual box and click enter or on search button, nothing happens at all. This is very annoying! I would appreciate any help.
Thanks.

I just went to the Help>Troubleshooting Information>Open Containing Folder>Organize>Select All then deleted everything. When I reopened Firefox my homepage asked for my password, the option for Firefox to remember, I clicked remember and now it is working.
By the way the previous post was me as well. Just a typo, should have been stlblues1226 as well.

My browser has been infected with a virus that is not showing up in a scan. When I do a Google search and click on the desired site, I am diverted to some completely unrelated commercial site. Can this be fixed? in English

In Firefox I did a search for Alaksen ( wildlife refuge). The search results were appropriate. Clicking on any site in the Google search diverted me to various commercial websites that were completely unrelated to Alaksen.

Try running several malware scanners. It is best to run several as each will pick up things that the others miss. Some scanners you can try are:
* Malwarebytes - http://www.malwarebytes.org/mbam.php
* SuperAntiSpyware - http://www.superantispyware.com/
* Ad-Aware - http://www.lavasoft.com/products/ad_aware_free.php
* Windows Defender - http://www.microsoft.com/windows/products/winfamily/defender/default.mspx
* Spybot S&D - http://www.safer-networking.org/en/home/index.html
This link may also be of use - http://deletemalware.blogspot.com/2010/02/remove-google-redirect-virus.html
If the above malware scanners do not find any malware or can not clear it, you should consider posting in one of these forums for specialized malware removal help:

There are different variants of names for this malware but the steps of removal should be the same unless it has advanced.

I would like know if there is any timestamp feature in Project Server 2007, so that it can be possible for Project Managers to know when a task has been updated for the last time.
Thanks in advance

Hi,
If you are using the My Tasks to drive the task updates then you can use the 'Applied Requests and Errors' available under 'Go To' in the Task Updates area. Here the PM can find when requests have been approved and how many updates he/she received for a
particular task (by clicking the task name) etc.
Hope this helps
Paul

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.
