Some Virus Questions
I have been trying to stay as safe as possible
in my web life recently. I was getting a bit
overconfident because of the Macs reputation.
I have had only Macs going back to OS7.
My questions are
#1.
When I finally get a Intel Mac and heaven
only knows, if for some reason wanted to run
windows on this Mac, does it now become as
vulnerable as a normal PC to attacks?
Would I then have to do the whole spyware/
viruse regiment on the computer as a whole or
would the Mac side still be insulated against
the PCs bugs?
#2
I have a fairly large collection of cassette
tapes. I have been kind of lazy in that instead
of digging out a tape for a song I want to put
on my ipod and having to convert it to a digital
format which is kind of a pain.I would just
download it from a file sharing program. I heard
a podcast where they said that viruses could be
hidden in the mp3 files. Is this a concern for
Mac users or a real threat?
#3.
I learned about Root kits recently and was
wondering if there is a utility for finding
them on your machine? Is this something that
is not possible on OSX because of the Administrator
password necessary to install a program?
#4.
I recently had my Airport die so I am using
only the software firewall which according
to the GRC website was very secure.Heres what
their sites said when it tried to access my machine.
Your Internet port 139 does not appear to exist!
One or more ports on this system are operating in FULL
STEALTH MODE! Standard Internet behavior requires port
connection attempts to be answered with a success or
refusal response. Therefore, only an attempt to connect
to a nonexistent computer results in no response of
either kind. But YOUR computer has DELIBERATELY CHOSEN
NOT TO RESPOND (that's very cool!) which represents
advanced computer and port stealthing capabilities.
A machine configured in this fashion is well hardened
to Internet NetBIOS attack and intrusion.
Unable to connect with NetBIOS to your computer.
All attempts to get any information from your computer
have FAILED. (This is very uncommon for a Windows
networking-based PC.) Relative to vulnerabilities
from Windows networking, this computer appears to be
VERY SECURE since it is NOT exposing ANY of its internal
NetBIOS networking protocol over the Internet.
Should I take this with a grain of salt or is
it right on? I received similar results in all
areas. I do get numerous entries in the logs
about stealth attempts to connect to my computer.
It is amazing how often it happens (many times everyday)
This is why I having been stepping up the vigilance.
Thanks for all your thoughts. I admit I am
a little paranoid but with phishing and zombies,
I do think the internet justifies it sometimes.
Hi Wayne,
Regarding your question,
This is what I did:
Using Secure Empty Trash from the Finder menu:
After running the full scan as I described in the previous
post now set preferences in ClamXav to quarantaine the
corrupt files in a folder on my desktop named "Birdcage"
I set the preferences to look for '.rar' extensions.
(The elaborate scans showed 2 infected files with the
'.rar' extension, all scans described in this post run in
these settings)
The HD scan resulted in 1 infected file.
(this is a little strange because there where 2 infected
files reported after the force trash experiment described
in the previous post)
Log output:
/Applications/Utilities/Installer.app/Contents/PlugIns/Documents
/Office 2003 - Fully Registered.rar: Trojan.IRCBot-725 FOUND

Scanned directories: 129927
Scanned files: 4392
Infected files: 1
Data scanned: 122.96 MB
Time: 105.848 sec (1 m 45 s)
I know there are at least 2 infected files so I scan my
personal folder seperately, and infected file 2 is located
only after I individually selected my personal folder, and
gets automatically quarantained in the folder "birdcage"
on my desktop.

Data scanned: 122.96 MB
Time: 105.848 sec (1 m 45 s)
I have a Raid set with 2 external HD's, I scan them 1 by 1.
They show no '.rar' executables.
The log output:

Time: 17.338 sec (0 m 17 s)
Now I have a file on my desktop with two infected files.
I drag them to the trash and choose "secure empty trash"
from the finder menu.
I run a full scan with ClamXav and now I do not get the message:
ERROR: Can't access file /Users/janpietermelchior/.Trash
/Office 2003 - Fully Registered.rar
But:
Log output:

Time: 12805.845 sec (213 m 25 s)
1. I backed up my important files after running the
ClamXav scans and removing the infected files, and
installed a new osx.
2. I did not import keychains from another computer
after booting the new osx I (read somewhere this a
solution for the diskpermissions). I checked wether
my disk permissions where restored by choosing
Disk Utility in the /Applications/Utilities folder and
refer to Disk Utility Help. "verify permissions".
3. After downloading ClamXav, it promted me to donate,
I did this after I removed the infected files.
4. As Mac OS X is essentially a UNIX-like operating
system,the ClamAV project has recently pledged improved
support for it, which includes the adding of any potential Mac OS X
malware to the definitions list. Of course, this implies that the community reports such programs to the ClamAV authors and that they
in return judge the threat of significance so that they act upon it.
Unfortunately they do not have a database of Mac infections
or other malware.
5.After the proceedings described above ClamXav did
not report infected files.
I am not aware of infected files that are residing on my
harddrive after running ClamXav, backing up and installing a new osx.
Many thanks to ClamXav, it is the only virus scanner I ran
that located these infected files.
I entered my creditcard data for a donation.
Hope this kind of answers your question Wayne, I hope the files are gone.
If anyone has advice on what i did or sees that I made a mistake, or could
do better please inform me a.s.a.p. I never had a pc.
I'll keep you posted.

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM...
I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM?
Is there any way to get more VRAM to play games on steam?
I've learned by reading other topics that I can't upgrade my graphics card on my Macbook Pro because it's soldered into the motherboard or somthing like that, but please tell me if there is any way to get more video ram by chaning some setting or upgrading something else. I'd also like to know why I only have 256MB of VRAM when I have 8GB of RAM, since I have 8GB of RAM I thought I was supposed to have 560mb of VRAM...
So the two questions are...
Is there any way to upgrade my VRAM, so that I can play games on steam?
Why do I only have 256MB VRAM when I have 8GB total RAM?
Other Info:
I have a quad core i7 Processor.
My graphcics card is the AMD Radeon HD 6490M.
I am also trying to play games on my BOOTCAMPed side of my mac, or my Windows 7 Professional side.
THANK YOU SO MUCH IF YOU CAN REPLY,
DylanThe only two items that a user can change on a MBP are the RAM and HDD (Retinas not included). You have what the unit came with and the only way you will be able to change that is to purchase a MBP with superior graphics
If you are very much into gaming, the I suggest A PC. They are far superior for that type of application to a MBP.

So I have a problem with iTunes not letting me download anything without first responding to some security questions which I don't remember setting up, how can fix it? Oh, and it won't let me reset the questions either!
If you mean that you aren't getting the reset link, then from the page that you posted from :
Note: The option to send an email to reset your security questions and answers will not be available if a rescue email address is not provided. You will need to contact iTunes Store support in order to do so.
You can contact iTunes Support in your country via this page : http://support.apple.com/kb/HT5699
When they've been reset you can then use the steps half-way down the HT5312 page that you posted from to add a rescue email address for potential future use -
How do I recover the program for Photoshop Elements 12 that was wiped off my computer when they removed some viruses? I no longer have the program because I bought it on-line and downloaded it instead of having the program disc. I bought it last year and can't seem to contact anyone at Adobe or find out who to call.
You can download it here:

Some basic questions on File Adapter
Hello all,
I have some basic questions on XI and File Adapter and hope you can help me. Any answer is appreciated.
1. Can I use NFS transport protocol to poll a file from a machine in the network, which is not the XI? Or do I have to use FTP instead?
2. If I understand it correctly - when using the FTP-File Adapter, XI has the role of a ftp client. I have to run a ftp server on my distant machine. XI connects to FTP-Server and polls the file.
Can it also be configured the other way round? The scenario I think of would be: FTP client installed on distant machine, which connects to FTP-Server(XI) and loads up a file. So XI would act as FTP Server.
I know this works, if I install a ftp Server on the computer my XI runs on, and use the NFS-File Adapter to observe the folder. But I want to know, if I need a second, independant ftp server for this.
3. And last but not least: When do I need the active ftp mode instead of passive?
Thanx a lot for your answers!

Some generic questions on BPM of NW CE
Hi Gurus
i have over 6 years of ABAP business workflow experience and over 3 years of XI experience. Now i'm getting tough with this new stuff, BPM of NW CE. Here i have some generic questions of it:
1. How can i trigger a BPM task while a document, like a sales order , has been created in the system? is there any processes to catch the event of R3 in NWDI?
2. Can BPM consume RFC/BAPIs in R3?
3. Is it possible to make message mapping in BPM? i found there is a 'mapping' choice in the context setting of NWDI whereas it is quite simple compared with PI.
4. Can the BPM be integrated with webdynpro ABAP? or send the relevant tasks into R3 directly? Actually what i mean is , can i bypass java programing while dealing with BPM of CE, if possible.
thanksHi Stephen,
In the first released version of SAP NetWeaver BPM it is not possible to catch events of R/3 directly. Anyway. In case you have the possibility to trigger a web service in that situation you could start off a specific (BPM) process instance that handles the situation.
The same is basically true for the question regarding RFC: In the initial version you'd need to wrap the RFC into a web service in order to consume it.
The mapping possibilities in SAP NetWeaver BPM are meant to perform data flow between different activities in a BPMN based process model. This way you could transform a message that came into the process in that way that if fits your needs in regards to the BPM process (data) context.
Bypassing Java when using SAP NetWeaver BPM would be difficult as the supported UI technology is Web Dynpro for Java. In addition the possibility to add more flexibility to your mappings by defining custom functions is based on EJB, thus again Java.
Best regards,

I have a jailbroked iphone,and it seems that it has some viruses how can I remove them from my iphone?
You have viruses because you jailbroke your phone, and now you're probably spreading them to other phones. Nice.
Jailbroken phones are generally bricked for good. Throw it away, it's junk. -
hello all, as this forum has many brilliant minds, i have some interview question, if you mind please let me know the answer....
q1. default level at which validation accurs?
q2. in which case property pallet display **** as a property value, what its meaning?
q3. best way to ensure that item can not accept query criteria?
q4. what is the use of key-other trigger?
q5. what is the use of forms module validation unit. if it is set to form then data block pre-text-item trigger at point will raise?
i tried but did not find any relevant answer.Hi yash...
q1. default level at which validation accurs?Well, the default level is where ur trigger exist ( Form Level ,Block Level or Item Level )
q2. in which case property pallet display **** as a property value, what its meaning?Conceal ; it means hiding displaying data and it is almost used in password text item.
q3. best way to ensure that item can not accept query criteria?Well, actually i don't have any forms now but u could try it urself item property > query criteria (any related query allowed property ) >NO
q4. what is the use of key-other trigger?A Key-Others trigger fires when an operator presses the associated key.
A Key-Others trigger is associated with all keys that can have key triggers associated with them but are not currently defined by function key triggers (at any level).
A Key-Others trigger overrides the default behavior of a Runform function key (unless one of the restrictions apply). When this occurs, however, Oracle Forms still displays the function key's default entry in the Keys screen.
Hope this helps...
Good Luck :)

Some simple questions regarding the Xcode.
I have some preliminary questions regarding the Xcode (objective C):
What is the difference between the programming files followed by .h and .m?
What does an asterisk * followed by a text mean (i.e. *window;)?
Is there any source that briefly explains the most common codes with examples (nsstring, nsarray, iboutlet, inaction.....etc)?
Any other tips will be highly appreciated.
Many thanks.Xcode is the IDE.
Objective-C is the most common language used within Xcode.
UIWindow *window ..... the * means return the address of the instance variable 'window'.
An * is called a pointer to a variable.
Everything you need is explained here: https://developer.apple.com -
Some basic questions from a mac newbie
hi,
i have been using linux and windows all this while, and recently began using an apple too. have some simple questions here that i hope to get some answers for.
1. is there something similar to /etc/hosts in linux where i can add the IP address of a server? this is for me to use the 'ssh' command in the terminal
2. when i open up an application, say safari or chrome, i want the window to fill the entire screen automatically, instead of having to drag the bottom right of the window to fill the screen. how to configure that?
3. when i close an application by clicking on the 'x' at the top left, why is it that it still appears in the list when i press command+tab? to remove the application from the list, i have to right click on its icon on the dock, then click 'quit'. this is rather troublesome.
appreciate any help!1. is there something similar to /etc/hosts in linux where i can add the IP address of a server? this is for me to use the 'ssh' command in the terminal
The /etc/hosts file is there, but the /etc/ folder is hidden. You can use the Terminal (in /Applications/Utilities/) to access it via Unix, or could enter "open /etc" in the Terminal to open that folder in the Finder.
However, I'm not sure how this relates to ssh... I have not needed to modify that file, yet I can ssh all I need to. Are you trying to connect to your new Mac via ssh, or connect to other machines from the Mac via ssh?
2. when i open up an application, say safari or chrome, i want the window to fill the entire screen automatically, instead of having to drag the bottom right of the window to fill the screen. how to configure that?
Just drag the window out to full-screen and the browser should remember and open new windows at that size in the future. There are also some utilities (one called "Right Zoom" IIRC?) that will make the zoom button (green + button) behave more like the Windows zoom button.
3. when i close an application by clicking on the 'x' at the top left, why is it that it still appears in the list when i press command+tab?
Applications shouldn't quit just because you close their last window, unless the application's entire user interface is contained within that window. That is the case with ALL Windows apps, since there's no global menu bar, but only in some Mac apps. This is something that always ticked me off big-time with Windows... there have been times when I carelessly closed a window I didn't need anymore, but wanted to keep using the app, and then had to wait for it to load again. That won't happen on the Mac.
If this bothers you, just use the key combination command-Q to quit apps. -

[email protected]Please think when you were at the beginer stage.Yes, I guess setting up a second machine under your desk and spending the next - oh I don't know - 2 months fiddling around and trying out all kinds of things is really nothing that can be asked of anyone anymore today. </sarcasm>
Mind you, my boss at the time did not find it funny that I just formatted a surplus workstation and monopolized it, but when I then took the first official training I had a whole stack of questions at the ready with which to hassle the teacher.
Now you tell me: which approach enables you to learn and understand more and better?
@rnm1978: +1!
