Mail virus and Trojan issues

I have a high end virus detection running on my Mac.


Recently I have had many Spam emails with attachments. The attachments had viruses or trogans, most likely Windows ones. When I marked them as 'Junk' there was no issue, then I deleted the Junk mail. When I rebuilt the mail boxes recently the virus checker picked up the viruses in the attachments.


Two things are of concern related to above;

1) the recent information about 650,000 Mac's worldwide being effected with flashback trojan, should basically have eliminated the thought that there is no necessity to use virus detection on Macs or at least have concerns about attack potential.


2) Why there was no issue until I tried to rebuild the mailboxes, basically meaning if you just 'erase junk mail' any future potential risk to Macs could be dormant or active, still on the HD. 'Erase junk mail' means the data is still in the mailboxes/HD, just not shown in mail, perhaps just the file headers removed.


It could just be a matter of time before Macs become a more active target, as most users are complascent about the potential for viruses and trojans, there are strong myths that Macs are safe against such attacks.


A good friend recently had an virus attack on his iPad that Apple technitians at the Genious bar were all interested in and they reported it back to Apple headquarters. So I think personally the time for complacency is over.


Any idea about what is going on with the mail boxes would be most interesting.


Thank you.

MacBook, Mac OS X (10.6.8), iPad & iBook OS 10.6.8

I don't rebuild the mailboxes every time I erase Junk mail. The virus detection kicks in only during the rebuilding of the mailboxes, which sometimes is one or two days later. If Erase Junk Mail command had erased these Junk mails, I was curious how the Virus detection kicked in later during rebuilding of the mailboxes.

When I observed the rebuild process last night I noticed that it not only rebuilt the mailbox index to match what messages were actually in the mailbox, but each of the email file names were changed to sequential numbers, indicating to me that it was also doing something to the messages themselves. The same thing happened to everything in the Attachments folder so that the file names matched the message they were attached to. That tells me that what Thomas said was correct, that everything in the mailbox is assumed to be new to the A-V software and needs to be scanned.

If the Erase Junk Mail command is run, it may not erase the Attachments Folder

Which was not the behavior I observed. Every time I used "Erase Junk Mail" when there was something in the Attachments folder, it was emptied at the same time as the Messages folder was.

Hi please help.

I have a iPad 2 , not jail broken, just 2 months old fresh from the apple store. Recently I have been directed to **** sites or a fake bad oink **** application, through various applications. From google chrome app, the photon app and safari.

I always delete cookies and cache on exit. I use photon and puffin to watch flash player videos on tv series site with links such as put locker. I heard that there is no virus for the iPad but Trojans do exist.

Pleae help, at first this was just happening with photon app now in 3 different apps, and it is directing me always to the same **** site. I don't watch **** so it's. it from cookies or whatever and my iPad has been randomly turning off and also the videos are working really badly now. Also there is a message red alert staying untrusted site and hacker may be intercepting your device. What is going on? Please help

Is their a new redirecting Trojan or virus for iPad 2. ? If yes how can I remove it and will it cause permanent damage to my device? How could I have got this virus and in 3 apps. I'm also,worried as I use my iPad to buy things online etc with my credit card. What shall I do?.. Do I restore my device? How do I do that as I cannot connect to iTunes as I do not have a computer, just my iPad. Any help appreciated thanks.

No, there is still no known malware capable of impacting any iOS device.

What shall I do?..
