Welcome to the Apple Support Communities
See > http://www.reedcorner.net/mmg On OS X, you don't have to worry about malware and viruses because Mac OS X has got its security systems. However, if you want to make sure that there isn't malware, you can use Sophos or ClamXav to scan your hard drive
Even if viruses aren't detrimental to Apple devices any file infected with a virus can potentially be spread to other PC's that they would do damage to.
I know a number of people that received fraudulent emails falsely claiming to represent legitimate companies. These emails had a zip file attached in attempt to infect with the Trojan Agent virus.
I had person from India renting out my spare room who requested internet access also be provided as part of his rent. He signed a rental contract which included internet access for $15/week.
I probably don't want to know what he did on the internet but during his tenancy internet usage was massive. This probably exponentially increased the risk of malware or viruses being a real threat to systems he was connected to. And while it may not harm a Mac, if hosting the infected data and transmitting it to a vulnerable system, the need for virus scans for all systems is evident.
One really easy way to prevent malware on your computer is to use Avira - freeware virus scanner.
It has Windows and Mac OS X versions and it protects your computer from the most malwares.
This is not maybe 100% percent the Best program what is out there but it should be more than enough for regular user.
I use this my self.
Thanks but I know how to act appropriately with malware.
Problems persist because the government does not know how to deal with internet security matters as evident in the attached response which was submitted as evidence in court. This was after 3 people called the police while I had this document in my possesion and the police called the author of the letter to confirm it's authenticity.
Persistent internet attacks are commonly classed as cyber-terrorism and the affects on systems should prompt investigation as counter-terrorism financing and anti money laundering guidelines. Not doing so is equivalent to throwing everyones personal information, like a dog with a bone, to perfect strangers.
Install firewall & Antivirus software.
I think we all heard you the first time. We haven't heard anything from the OP and it's been over a week since they joined and posted their one and only question to date, so I suspect they have all the info they need for now.
let's get back to the subject if problem still occurs.
What problem was that?
I need a little help with the topic of malware. I was attempting to update my Department of Defense ID card utilizing a card reader and the DEERS website. The requirements for doing so was to have Java Runtime Environent installed. I went to the Oracle webpage and downloaded JRE and was still not able to do so. I also went to CNET and downlaoded JRE, which I know I probably should nothave done. After doing so I had degraded internet access and several attempts to login to microsoft.com from an IP adress from Russia. I also received this email from google:

This email also has it orogin out of Russia which is leading me to believe that I have dowloaded soemthing I should not have done. I have ran wireshark and have not gone through everything yet but did not find anything unusal just yet. I subsequently installed little snitch with nothing unusal. I guess the question is if I am being paranoid or is did I download malware?
I doubt that many people will see your posting. It's always best to start a new discussion in cases like this.
A quick examination of the message indicates that it was sent using Microsoft Outlook Express 6.00.2900.5931, so it didn't come from your Mac.
Also, there is currently no known malware capable of sending bulk e-mail from a Mac. If it came from your Mac there should be evidence of it in your Sent Mail folder.
The majority of spam e-mail is sent using a forged From: address. Since you received a non-delivery message from Google, I suppose it's possible it was sent from your account on the server. Again, there may be evidence in the sent mailbox on the server of it having been used, but spammers have also been known to erase them after they finish. If this continues then I would change my e-mail password and make certain the spammer has not set a preference to allow a second account access. This is often done for businesses to allow a secretary to send e-mail out for their boss.
Back to the JRE you downloaded from C|Net. I checked and can only find Java JRE for Windows, which you should not have been able to install anything on your Mac, even though they have been known to include adware in their installers for Windows for some time now.
If you installed the JRE from www.java.com (run by oracle) you should have the latest working Version 7 Update 51. I've never tried to use a CAC card from a Mac, so I can't help you with that.
