Viruses On Os X

Thought I'd post about one type of virus that does effect Mac computers, I actually caught this one- Macros virusus.

This is the best application for finding and quarantining viruses for Mac. Clam Xav http://www.pure-mac.com/downloads/clamxavdl.html
It's free I use it all the time. If you trade files with PC users believe me you'll probably get at least one infected file in your lifetime. You need to go to Preferences and select "quarentine infected files" and choose a location if you want to actually take action on fixing them.

Macros virusus are probably the most common. They get into your system through applications that use Macros (Microsoft Word is probably the most popular). So step one is obvious: never enable Macros on a file, never. Still some virusus are quick tricky and can still embed themselves even if you deny enabling Macros

Most infect your templates, since formatted templates often utilize Macros functions, and then continue to populate your system as you use that template.

As a user you might experience frequent crashes, strange errors on saving (like stupid childish messages such as "Are You Surprised" and so forth). More than likely you will have absolutely no idea you have a virus.

Macros virusus are easy to code so they are abundant but luckily pretty easy to kill.

1) Locate the default template file for the application infected with the Macros virus and delete it. The templates are usually packaged with the application in a folder called user data or something similar- you can search for "template" and you should find it easily.

3)Any infected files can be disinfected by copying and pasting the text into a new document. If you seem to keep that virus in the copy save as plain text (import into text edit, go to format> make plain text then save as plain text). There's zero places for a Macros virus to hide in a plain text file but you do loose your formatting.

PS: SHAME on the person who posted to the user that they shouldn't get rid of the virus just because it doesn't effect Mac!!! First off it does, and will, second any documents that Mac user makes and sends to their PC friends will wreck havoc on their PCs. So always disinfect your computer- don't propogate virusus.

kiral, did you read the previous post before yours? I am not saying Randy is right, but the two posts seems at odds with each other.

By the way, here his Intego's explanation of VirusBarrier:

VirusBarrier ....... does not scan for all 60,000 or so Windows viruses and variants ...... it does scan for the latest ones and all of the Office Macro viruses [which] can affect the Mac version of Microsoft Office as well as the Windows versions ......... VirusBarrier is not a comprehensive tool for eradicating Windows viruses.

Just worth bearing in mind that relying on VirusBarrier to prevent passing on virii to PC users is not as reliable as one might hope.

Obviously he didn't, and he doesn't really know what he is talking about. There is quite a bit of misinformation about this topic being spread around, and it would be nice if folks didn't disseminate FUD (Fear, Uncertainty and Doubt) without really having a clue what they are talking about.

None of the anti-virus programs for the Mac scan for all of the *over 180,000* (not 60,000)

Windows viruses. They only scan for those Windows viruses that are spreadable to Mac users via e-mail, or as Word and Excel macro viruses. It is extremely unlikely tht Mac users will see other Windows viruses show up on their machines.

In any case, as I said, Windows users need to be responsible for protecting themselves from Windows viruses. Windows viruses are not Mac users' responsibility, and Mac users, unless they are are absolutely clueless, aren't going to be speading any Windows viruses. No anti-virus software is necessary to protect Windows using colleagues.

One note, to avoid all Word and Excel macro viruses, all that you have to do is turn on "Macro Virus Protection" in Preferences in Word and Excel. You don't need anything else for this.
 
Kiral - just a note on English. The verb to "effect" means to "bring about" or "make happen". The verb you need is to "affect". Using the wrong verb doesn't help your credibility and I agree with Randy - especially since I've been using Macs since 1987, been on-line since 1995, and I have *never* seen a single macro, trojan or virus that would affect my Mac. In the early days I did receive a few suspicious attachments that could have been Windows viruses but I simply trashed them with a single click. I don't need software to do that for me!

Now you might say "you've been lucky" but, if so, I have a lot of friends in the Mac community who have also been "lucky". ;)
 
Which rather proves the point that so-called "virus protection" for MacOS can do more harm than good, unfortunately.
 
I downloaded an update that was to prevent virus through Microsoft word and now my Word is gone. How do I get it back?
I've never heard of an "update" (to what, to Word itself?) for this purpose. Where did you get this update? How was it installed?

Have you done a Spotlight search for Word?

Do you still have the original CD-ROM that Microsoft Office came on so that you can reinstall it?
 
I dont have the disk becuase I got office from a friend. I tried to use spotlight and it found the test version that comes with the computer. I will have to find somebody else with the disk to re-install word.

It was installed like every other update.
 
Absolutely agreed. There was a posting on one of my MacOSX mailing lists that quoted, and I don't know the exact source's name, but it was a large software firm, that viruses are non-existant for OSX. Malware is out there, but you have to search for it, and it's very easy to avoid it if you do find it.

So having read all these threads I'm wondering if my mail issue is virus or application related. I started having problems on Valentines day last week; after downloading security update from Apple. Now I keep receiving emails I sent last week, there are copies and copies of the same email being created and stored in my drafts folder, and friends are irritated because they are receiving the same email 35 times. I'm using iMail. I contacted by Internet Service Provider/Cable company and they assure me it's not their end.

Anyone got any ideas?

I installed Avast Virus software and that shows no viruses.....


Stumped!
 
A bit off topic but one thing I do not like (this is going to be hard to describe) is the pop up that says "Foo changed and is requesting permission to access your keychain". The message varies.

If I just updated Foo, then the message is great. I appreciate it. But I've had them pop up out of the blue and I honestly could not tell if it was valid or not. Maybe the solution is for all those pop ups to happen just after install... some how.

I like how I'm quized about running something I just downloaded. I've been worried about Trojan horses (e.g. something that looks like a jpeg but is actually an application) but this makes it harder for that to happen.
 
Hello, I have a few questions..kinda new to Macs. I know there are very few viruses for OS X 10.4... I think the iPhone's popularity has caused a few viruses to pop up but they technically shouldn't effect a computer right?
I have an iBook G4 and I use it in a college that is entirely Macintosh based, so I am concerned about file sharing and security from hackers. I have noticed there is a firewall in system preferences > sharing and I would like to know if it is potent? I know that stock PC firewalls are a joke but Mac is more serious about safety, so is it better?
Are there any free firewalls and virus protection available that does the job well? I need to get a few parts for the computer but virus protection is defiantly on the list..I know the stuff you pay for is better than the free stuff but I just want some thing that will work for now.

ClamAV

Mac viruses (two of them) need your permission to be installed. One of the OS X virus is a concept called the Newton Virus (but it is a joke trojan). Here is a video of it Newton Virus.

The second is installed by one going to an obscure porn site and it ask you to install a QuickTime plugin to view a porn movie. You can read about it at Macworld. the article will tell a user how to clean his DNS settings where it attacks.
 
Thats it? only two?
I dont use those kinds of sites, but does that mean any quick time plug in could be a virus?

Yes only two. The security level for Unix (BSD Unix is the core of OS X) requires your permission to install stuff where it could affect the system. Hence the different levels in the Mac Finder. Top level for the entire system, User level for YOU.

The second answer is No. It pretends to be a QuickTime plugin.

To protect you self go into Safari (or ant browser's preferences) and turn off automatic unpacking/installing. In Safari is is Preferences and then uncheck "Open safe files after downloading".

Lastly a little web commonsense can go real far in protecting yourself, on any computer platform.

Note: If you really want to be safe go to OpenDNS and use there DNS. Then go back to the site and create a free account. Then in that free account you will be able to block known phishing sites with adding additional software bloat to your computer. You also can block custom sites too. One added benefit using OpenDNS is many users (including me) saw quicker web site loading after using their DNS. That is way I recommend the service almost every chance I get.
 
Eh, I was downloading programs and I got one called Podview a week ago from versiontracker.com It asked me for my password and I pput it in ...Doh! It didnt say why but I thought it was to allow my ipod to send info back into the computer. The pprogram works and i havnt noticed any ill effects. I also took all of the @ symbols out of my adress book..I know windows version is very dangerous.. kinda assumed the same concept could be applied to a mac.


So that open DNS thing would make my internet run faster but all of my info would pass through them?

Yes. It is a simple case that most ISPs really have no clue on DNS. They don not keep up on the ever changing net.

Now if you really want piece of mind on a Mac then you get a program that monitors you connections outbound. That program (that I use) is shareware and it is called Little Snitch. You will be really surprised how many programs call home way beyond simple updating cues. Using the program seems overwhelming but the more you use it the less you notice it.
