HI! i just want to ask .. If Macbook Pro can get a virus?

Is your MBP doing anything odd that raises concerns for you? Or is it just a case that the USB is behaving oddly and has been plugged into your computer in the past?

There really are no true viruses out there which affect Macs. There ARE examples of Malware, poorly implemented programs, occasional Trojans etc.

Chances are that even if there WAS a virus on the USB stick, your MBP operating system would prevent it doing anything nasty to your computer (without then need for anti-virus software).

I'm not sure why you are saying this.

XProtect is the native anti-malware program on Macs since 10.6.7, I believe. It will only recognize malware it has already cataloged and it does not recognize dangerous files, even if they are cataloged, if the source is a USB connection, like a flash drive.

To the OP: I would suggest getting VirusBarrierExpress and using it to scan your entire drive. Or reconnect that flash drive and see if you can get VBE to scan it alone. It's available free at the App Store. But there again, if a threat hasn't been cataloged, it will be useless for finding it. You shouldn't therefore conclude that if nothing is found, it necessarily means that no exploit or infection has occurred.

I really don't understand your first post; it's very confusing. Can you please explain more carefully, perhaps with some punctuation (periods, commas and capital letters at the beginning of a new sentence would help a lot) what made you think there might have been some kind of malware (virus) on the flash drive (USB stick)? Or if if it wasn't a concern about a USB flash drive, can you say just what your concern was that prompted asking this question.

I would not worry. And no, I don't think you need anti-virus. On the whole, antivirus programs on Mac tend to slow up OSX, cause problems and try to solve problems that don't exist.

Don't worry, use your Mac, be happy!!!!

It's very difficult to understand the problem due to your style of communication, as WZZZ has pointed out. However, it sounds like whatever the problem is probably is an issue with that USB flash drive. Perhaps it is formatted in a way that the Mac cannot deal with in the same way a PC can (NTFS, for example, can be read but not written to on a Mac), or it may be damaged in a way that the Mac is having a problem with and the PC is not.

In any event, this is not due to a virus, or any other kind of malware. That said, it's also not true that your Mac can protect you from everything, or that you can put aside all worries. Strawb268 is setting your mind a bit too much at ease, and this could end up getting you infected at some point. See my Mac Malware Guide for more information, and see Time to re-evaluate safety of Mac OS X for information about malware that I have tested against Mac OS X and found to still be of concern.

Unfortunately, VirusBarrier Express is no more. It has been removed from the App Store by Intego. See:

VirusBarrier removed from App Store

EDIT: meant for Thomas.

That is unfortunate. Just downloaded new defintions, so at least that's still working. Have also been running Sophos on my 10.6.8 the past week. No problems at all, so far, although site loading is a tiny bit slower than before. If that's the only issue, then I think it's worth the trade off, at least for running Snow.

Thanks thomas_r. (and WZZZ) for clarifying.

I had not intended to foster over confidence or complacency on the part of the OP and I do tend to make a distinction between Virus and Malware that is not in the thinking of many who post here. As I said in an earlier post on this Thread, there ARE examples of Malware, poorly implemented programs, occasional Trojans etc. all of which have the potential to affect Macs.

I also fully accept that new and unrecognised malware will not be picked up by XProtect.

I think Klaus1's User Tips are rather helpful:

(and, of course, your Mac Malware Guide thomas_r. !!!!).

Not only that, but as I pointed out before, XProtect only quarantines a limited number of sources.
