Old external drive; how to check for virus?
I`ve an old external drive from the time I was a Windows PC user. I just don`t want a virus on my macbook, so I want to make sure that the drive is clean, and wipe out all the deadly ****. So, what do I do? PS, I have really important stuff in there too, so I cant just reformat the drive.

Download and scan it with either Sophos or ClamXav. Not that Windows viruses can affect the Apple OS:
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.

Received an email from a friend telling me an email they sent which may have contained a virus
should not have been opened but I had already opened it!Probably your computer is not infected with any virus.
Am I infected?

Help! How to check for virus on IBook G4
Okay, I have been getting the multicolored swirly ciricle thing when I try to do anything online or though word on my Mac, it is significantly slower and has done this before. The tech support guy showed me how to scan for viruses and restore it after they were found. Can anyone help? Thanks.
Welcome to the iBook Discussions!
Since there have not been any viruses released in the wild that will infect a computer running Mac OS X, it's not a virus that is causing the trouble. If all you want to do is search for a virus, you can use ClamXav. But, we can be fairly certain this won't really clear-up your trouble. Is there any other troubleshooting you've tried? Have you used the Disk Utility (in your /Applications/Utilities/ folder) to "repair disk permissions"? Have you started up from your Mac OS X install disk and used the Disk Utility there to "repair disk"?

I have an old external drive with a firewall connection-How do I use this on my Mac with it's USB3 ports?
Does your Mac have ThunderBolt ports?
There are ThunderBolt to FireWire adapters.
As far as I know there are no FireWire to USB 3 adapters.

Is there a program that will check for viruses or other reasons why it runs slow?
For several months my iMac has been running slow or freezing often. Safari often quits unexpectedly as does mail on occasion.
Programs that check for viruses are a major cause of slow Macs, so let's look at doing steps that don't handicap your computer:
1) How full is your hard drive? You need a minimum of 10G free for background processes such as Virtual Memory.
2) How much RAM is installed? RAM for the Mid-2010s is rather cheap at the moment, I upgraded my 27-inch Mid-2010 recently from the original 4GB to 12 GB for about US$55. Installation took only minutes.
3) If you have an external hard drive for backups, are you using something other than Time Machine to do the backups. Many third-party backup programs can cause a performance hit.
The next step is a little longer. It checks to see if some runaway background process is eating processor cycles and slowing you down:
1) Use your computer normally for typical tasks for several hours, then quit any applications you have launched. Do not restart.
2) In Applications > Utilities, find Activity Monitor. If you've not used it before, you have to change a setting. At the top of the AM window is a "Show" option. By default it is set to show "My Processes." Change it to "All Processes" like this:
4) Now highlight the "%CPU"column as shown so the most active processes "bubble"to the top (tiny arrow points down).
Now watch things move up and down for a minute of two. What you are looking for is any single process that is using more than about 10 percent of the processor cycles while the computer is idling. If you see one doing that, post its name in a reply here.
Awaiting your report,

What kind of external drive should I get for my macbook pro for backups etc
what kind of external drive should I get for my macbook pro for backups and storage
Hi, i have a Mercury Elite-AL Pro from OWC, www.otherworldcomputung.com
this is the one;
http://eshop.macsales.com/item/Other%20World%20Computing/MEAQ7S1TB32M/
have had this for over two years, moved around a lot with the drive, ( to date ) no problems, they have good after sales support; give them a call if you need info.
There are a lot of drives out there as others here will let you know, there are good NAME drives but they also fail, POPULAR drives also fail, select the one you are happy with for your system and how you plan to use.
i suggest if $ is not a problem get a big drive you will find someting to put on it and is better.
hope this helps. -

How to check for updates on SCM packages?
Hey guys,
I wondered for some time now how to check for updates on SCM packages, i.e. -git
or -svn ones. Updates for binary packages are automatically updated by pacman,
no problem there. Checking for updates on non-SCM packages from the AUR is
easily done with one of the various helper tools available (personally, I use
slurpy).
However, SCM packages can change without their PKGBUILD changing, so I'm not
notified that I should recompile and update them.
Is there a "proper" way of doing this? Am I missing something?
Thanks in advance!If your system is booting then u can say that your bootblks are installed.Usually BootBlks are present in 0 & 1 slice of UFS Filesystem
/usr/platform/platform-name/lib/fs/ufs
directory where ufs boot objects reside.
An x86 FDISK partition for the Solaris software begins with a one-cylinder boot slice, which contains the partition boot program (pboot) in the first sector, the standard Solaris disk label and volume table of contents (VTOC) in the second and third sectors, and the bootblk program in the fourth and subsequent sectors. When the FDISK partition for the Solaris software is the active partition, the master boot program (mboot) reads the partition boot program in the first sector into memory and jumps to it. It in turn reads the bootblk program into memory and jumps to it. Regardless of the type of the active partition, if the drive contains multiple FDISK partitions, the user is given the opportunity to reboot another partition. -

hp laptop is slow to start checked for virus none found
Hi,
Shut down the notebook. Tap away at the esc key as you start the notebook to enter the Start-up Menu. Select the Bios option ( usually f10 ) and under the Advanced or Diagnostic tab you should find the facility to run tests on both the Hard Drive and Memory. Post back with the details of any error messages.
If both the above tests pass, try the following.
From the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'. In to the prompt type the following command and hit enter.
sfc /scannow ( note that there is a space between sfc and the / )
Let the process complete, then type exit and hit enter.
Next, click the Start Menu, click Computer, left click Local Disc C once to highlight it, right click Local Disc C and select Properties. Click the Tools tab and then click the button to 'Check the Drive for Errors'. In the following window make sure both boxes are ticked and then click Start. Agree to schedule the check at the next system restart and then restart the notebook - this process can take several hours to complete before loading back into Windows.
Regards,
DP-K

How to check for a function module with its description and functionality
Hi all,
How to check for a function module,with its description and its functionality,in detail how can I know the purpose of a particular function module,how to search for a function module which suits my requirement .Hi,
You can search a FM of your requirement by putting in the Key words and searching for a FM. Like * KEYWORD * and then pressing F4.
Say for example you need to search something regarding converstion.
Search for * CONVERT * and press F4.
If there is something specfic like converting date to something you can give
DATE * CONVERT *
OR
CONVERT * DATE * and press F4.
Once you narrow down your search you will have a Function module documentation inside the Function module. Please note that all the FMs willl not have documentation.

Want to know how to check for new line character in text file
Hi All,
I`m trying to read data from text file. However I`m not sure whether the data is in 1st line or nth line. Now I`m trying to read the text from the readline. But if text is "" and not NULL then my code fails. So I want to know how to check for new line character and go to next line to find the data. Please help.
Thanks
static int readandwriteFile(Logger logger,String filepath){
BufferedWriter out = null;
BufferedReader in = null;
File fr = null;
int get_count = 0;
try {
if(new File(filepath).exists())
fr= new File(filepath);
System.out.println("FileName: "+fr);
if(fr != null){
in = new BufferedReader(new FileReader(fr));
String text = in.readLine();
if(text != null){
get_count = Integer.parseInt(text);
in.close();
else{
get_count = 0;
else{
out = new BufferedWriter(new FileWriter(filepath));
out.write("0");
out.close();
} //Reading of the row count file ended.
catch(Exception e) {
e.printStackTrace();
finally {
try{ if (in != null) {
in.close();
if (out != null) {
out.close();
catch(Exception e) {
e.printStackTrace();
return get_count;
}You are calling the readline() only once which means you are reading only the first line from the file...
Use a loop (Do-While preferably)
do{
//your code
}while(text == "") -
My MacBook Pro hard drive is almost full and I wish to store my Aperture Library on an external drive, how do I do this and is the use of USB2 suitable or do I need to use a Firewire external hard drive?
You'll get better performance if you use a Firewire hard drive (especially if you buy a 7200 RPM drive). Firewire's IO speed is significantly faster than USB 2. USB 2 has a theoretical max speed of 480 Mbps except that it has extremely high over-head. The fastest speeds you can typically get are about 300 Mbps. Firewire, on the other hand, has very little overhead. The fastest speeds you can get are very nearly 800 Mbps. You will typically be constrained by the maximum read/write speed of the drive, not the speed of the I/O on the Firewire bus. Now if you had one of those nice shiny new Macs with the Thunderbolt I/O and a Thunderbolt drive (Light Peak) ... I think they alter space and time so that your data arrives before you know you want it.
Also... unless you want to buy a solid state drive (very expensive), try to keep your hard drives from becoming much more than about 60% full if you want great performance. A nearly "full" hard drive is, on average, only about half as fast as the same hard drive when nearly empty.
USB 2 will work perfectly fine... just not as fast.
Also... it's much safer to move the entire Aperture library than to "relocate masters". Your images must be managed. You can Aperture manage them, or you can manage them. But someone has to manage them. If you "relocate" them so that they are no longer stored inside the Aperture library then you'll need to work out a system of how you decide to organize things and it's critically important that you don't start moving files around or deleting things without Aperture's knowledge. If you do, you'll break the links to your masters and start having problems with missing masters. If you have Aperture manage the library then you don't need to worry about any of that stuff.... it's safer.
Do make backups (use the Aperture Vault or use some other backup program, but make sure you back up your work if you care about it.) There are only two kinds of hard drives in the world: (1) those that have failed and (2) those that are going to fail. There are no exceptions to this rule. Hard drives are cheap. Backup software is built into Aperture and into your Mac. -
