How can I detect BackDoor.Flashback.39.
edit: I DID a search, and found several 'fixes' regarding this trojan, but frankly, I am not confident enough to start deleting files as many recommendations suggest. Is there a program that will detect, and destroy or clean this trojan? I saw reference to Virus Barrier. Do you know this works on this particular trojan?
I'm running Sophos, but I don't know if Sophos would catch and clean this particular trojan. Any thoughts?
Thanks much!
You would be hard pressed to get any better explanation than Topher Kessler's.
As for Sophos, no, all it can do is detect an past variant of the Flashback trojan, and as such its utility is limited at best.
To remove this trojan with complete certainty, I am unaware of any method other than the drastic measure of completely erasing your hard disk and reinstalling OS X. Resist the temptation to download some magic bullet. There is no such thing.
The next threat to be aware of is exactly that. Spread fear and then sell you its cure. The fear is imagined - or at least overstated - and the cure is snake oil.
If you want to avoid all possibility of future attacks, it's easy, open your Utilities folder and disable Java in Java Preferences. If you get the following dialog:
... then it's not even installed, so don't install it.
Also, disable Java in Safari Preferences. I believe it is disabled by default anyway. I have never found anything that requires it, but if you really need Java to run then you must be aware of the possibility of attacks such as this. Nothing can install itself on a Mac without your explicit consent by providing a user name and password so if you don't know or don't understand why you are being asked for it then don't provide it.

How can I detect a dialog and respond?
I'm having trouble doing something that's probably not that hard. I'm trying to "Print to PDF" a bunch of old AppleWorks documents. When you open a document created in AppleWorks v6 it opens right up, but when you open a document created in AppleWorks 5 you get a dialog box that says, "This document was created by a previous version of AppleWorks. A copy will be opened and "[v6.0]" will be added to the filename."
Right now I open the file and then:
tell application "AppleWorks 6"
activate
repeat while not (exists front document)
delay .2
end repeat
end tell
When the dialog box pops up, there's no front document so the whole thing freezes until you hit OK. How can I detect this dialog box and dismiss it?
Thanks
PS
When the box is open I ran this and got this result:
/usr/bin/osascript -e 'tell application "System Events" to get properties of windows of application process "AppleWorks 6"'

The simplest would be to set the application preferences in the script.
Like this :
-- *** set prefs ****
tell application "AppleWorks 6"
activate
set oldPrefs to its preferences
copy oldPrefs to tPrefs
tell tPrefs
set old version warning to false --doesn't show the old version warning alert
set converted file suffix to true -- append “[v6.0]” to documents converted from older formats
set locked file warning to false
set paint reduction warning to false
end tell
set preferences to tPrefs
end tell
-- *** end set prefs ****
--**** your script, example ***
set tfiles to choose file with multiple selections allowed
tell application "AppleWorks 6"
repeat with i in tfiles
open i
tell front document
-- do something
end tell
end repeat
end tell
--**** end your script ***
-- *** reset prefs ****
tell application "AppleWorks 6" to set preferences to oldPrefs -
How can I detect a certain text within a field within CASE using IF
Dear all,
for a transformation / generation of values receiving from R/3 into BW I try to
manupulate three fields. I have a problem detecting a string in a field.
I am using a CASE with several WHEN clauses on one field. Depending on the
value, an IF is integrated. There I look into another field evaluating, if it contains
a certain string. E.g. IF STRING CP 'xyz' OR 'abc'.
System gives error for the locigal expression. I also tried CS, but same error.
How can I detect a certain text within a field and which is the right logical
expression.
Many thanks in advance!!!
ClaudiaHi,
Folow the blow example...
May be it helps....
DATA: hex1 TYPE string,
hex2 TYPE string.
hex1 = 'FFFF'.
hex2 = '123FF'.
IF hex1 CP hex2.
ENDIF.

Hello Everyone,
We all know whenever we try to connect to a PC which is not on network, we get UnKnownHostException etc..... by which we can detect that the corresponding PC is not an network(intranet/internet)
But when i send a msg from my PC to my PC, it works fine even if the network is down. I hv provided my PC's IP address instead of using localhost or 127.0.0.1 which reduces the possibility that the msg will not be traversed thru the network.
Any IDEA how this works.
Is There any possible way by which i can detect that my PC is not on network or the PC to which i'm trying to connect is not on network .......
Pls help me out, its really urgent as to be implemented in my Project
Thanks In Advance
Sahil ShaikhHello Surtee
I have developed a Messeging Service for the eCRM Apllication my company is developing and we r in the final stage of debugging.
Now whenever a user sends a msg to a PC which is not on network, the messaging service automatically sends an Offline mssg to that PC. But know i want ot distinguish wheather the PC to which i'm sending the msg is not on network or am I not on network based on this i need to perform diff. actions, hence i wanted to know that how can i detect .......
Pls see if u canhelp me out ......
Thanks

How can we detect a virus on our mac?, How can we detect a virus on our mac?
We think we may have a virus from the USPS spam email. How can we detect a virus on our computer?
What makes you think there is a "virus"? Any symptoms...?
There are other types of malware (such as trojans) that can affect Mac OS X, but no viruses. A trojan would have to trick you into installing something (the malware) by making you think it is something else. You would be notified (by the system) that you are running a downloaded application for the first time, AND if something will be done to update your current system, you will be asked to authenticate (with your admin user name and password). If something like that comes up when you don't expect it, you should be suspicious (and NOT authenticate). Just opening an email won't do anything, even if it's an email that may affects Windows PCs.
This free utility can scan your Mac for malware.

All of the examples shown around those samples are using After Effects to get the effect. You should look into that if you have it available. Otherwise, you will need to experiment to get something that might come near to those effects where you use blur filters and property variations of images sitting above images.

How can I detect in Business HTML that the app was called from portal?
How can I detect in Business HTML that the app was called from portal?
I need to distinguish whether the application was called from portal (URL iView) or by using an URL outside of portal.
So what I'm looking for is a variable or function that can be used like this:
`if (~within_portal==1)`
do this if called from portal
`else;`
do that if not called from portal
`end;`
For example, can I check in the program that there is a SSO2 cookie from the portal?
I'm using Integrated ITS in Basis 700.Here is the trick:
if (sapwp_active=="1")
in portal
else
without portal

How can I detect if I'm running a compiled versione of my application?
In my application I have included some special functions I don't want my customer to use. Since I will distribute the application as an .exe file, instead of cutting away those functions before releasing the .exe, I want to hide them when the application is runnig as an executable, and leave them active when running in the LV environment.
How can I detect if I'm running an executable or the LV environment? Do I have to scan the application name until I find an .exe different from labview.exe or there is another way to obtain the flag (something similar to CVI function InStandaloneExecutable() for example)?

How can i detect if the picture or swf file is produced from legal flash?
I have recently bought images and swf files from a student for my website.
I've just realized that the images and swf might be from pirated flash product because i found out that
the original flash is really and i mean really pricey! I don't believe he bought an original product.
How do i detect if it is from a legal product? I'm worried as i'm going to put it in my website.
I can't get the guy who did this for me as he is in another country already.
If it is possible to detect this and it is indeed from pirated product, how can i make it legal again?
Please help.Hey Rob,
Its the same question, just that i want to know if it is possible to trace the source if the file is an image.
If it is not possible to trace the source be it a swf or an image file, then i will just upload it to my website.
I wouldn't bother to check if it came from a pirated flash product.
The image is created from flash 8 just for me. It is not downloaded from another source.
Thanks. -
