Mac OS X: Viruses and Security

Here is an interesting post on Macs and Viruses from Symantec's site. The most salient point I want people to get:

"Simply put, at the time of writing this article, there are no file-infecting viruses that can infect Mac OS X."

That's a pretty amazing track record considering OS X was initially released in March of 2001. We often debate on the show about the state of Mac virus and malware threats. In my not so humble opinion, the only reason to have antivirus software at this time on a Mac OS X machine is to prevent spreading them to Windows users (and even then, it would have to be done manually by the user!).

Even Microsoft loves the new Macs ;)

Listeners may remember me saying the only computer to buy for a new student is an Intel based Mac because it can run Windows and the Mac OS. This picture show even Microsoft agrees with me. :)



This picture is a demo of Windows Vista and Microsoft Office 2007 running on a Macbook Prop. Now THAT'S a ringing endorsement. More info can be found here.

Everyone, please have a safe and happy Independence Day!

XP's No-Reformat, Nondestructive, Total-Rebuild Option

This is a great article from Techweb that describes how to rebuild, repair, or refresh an existing XP installation without destroying anything. Oddly, Microsoft has kept this somewhat under wraps. It is a wonderful complement to our earlier post about fixing XP in eight easy steps.

The article can be found at this link. I recommmend printing this out and keeping it for future use (use the "Print This Story" option at the bottom).

ISASS Virus removal:
--This is such a complicated topic that we hve prepared a separate post on it.

ISASS Virus Removal/LSASS.EXE

A caller on 5/16/06 described a Windows problem which may (or may not) be the ISASS virus, a/k/a or related to the Sasser worm. He kept getting a 'file missing' message.

Note that there is a real, needed Windows program spelled "lsass.exe". The first letter of the genuine program is a lowercase 'L'.

The virus uses an uppercase 'i' and is written "Isass.exe". The confusion is undoubtedly deliberate on the part of the virus writers.

So we're not certain if the caller has the virus, or is actually missing a used resource.

See the other comments below. Here is Guy Moore's analysis:

Tips on this virus

Another source

Also after removing the Sasser worm users need to do Windows updates. There was a Windows patch that protected computers from this problem.

Using Stinger to remove viruses on Windows based computers:

1. Download the Stinger removal tool using another computer

2. Put Stinger on a floppy then write protect the floppy.

3. Boot in safe mode and choosing the DOS option which I hope will boot OK.

4. Switch to drive A: by typing:
a:
then hit the return/enter key

5. Run Stinger by typing:
stng260
and hitting the return/enter key
Note: In this case "stng260" is the name of the Stinger application. This name may change so look to see what its name is when you download it.

6. Let it scan and clean up the problems

7. Remove the floppy

8. Re-boot hopefully it will boot properly

9. Check for Windows updates right away. Some of these things have had security updates that protect you from them.

Also -- here is a message sent too late for inclusion in the show, from Shawn M.:

"For the lass.exe missing file. I would use the XP installation disc and use the "Repair" windows option. This should reinstall the corrupt or missing file, without losing current files on the HD, , , Great ShoW!!!!"

Finally, we heard from the original caller, Mike O., who had the 'file missing' message:

"I found what I was doing wrong when I could not create the 6 XP boot disks. I now have the 6 disks. My error was that I thought the download from windows would create the disks. That was wrong. A program is downloaded which when executed creates the 6 disks. Got the answer via my son who is kinda a nerd, and he asked me a simple question. (What are you trying to load -- the download program or the program output?) God Bless the American school system."
