NOTE: Ubuntu 14.04 LTS was used for this.

I spent some time researching top-rated, but free antivirus security software for both Mac and Windows. There are far more free antivirus software solutions out there than listed here--I focused solely on those receiving positive reviews from respectable sites and/or testing labs. I also tried to limit the search to those offering both Mac and Windows versions.
This hunt was sparked by a personal incident where malware slipped past my AV software defenses. For obvious reasons that software did NOT make the cut. I needed to find something better, so the hunt began. Here's the list I compiled along with my snap impressions.

PROBLEM
Once in a while I am unable to delete an email message on my iPhone. It throws an "unable to move message to trash" error message. I use the normal iPhone Mail app and have an MS Exchange mailbox that syncs with my office email.
While this problem was well-documented for IMAP mailboxes, I could not find a solution for MS Exchange mailboxes.
SOLUTION
Turn off the mail sync, then turn it back on.
* Settings
* Mail, Contact, Calendars
* Touch your Exchange email account. You'll see a list of the things it syncs (e.g. Mail, Contacts, Calendars, etc.).
* Turn off the mail sync.
* Open the Mail app to confirm that your Exchange mailbox is no longer there.
* Return to the settings and switch the mail sync back on. Your mail will be re-synchronized with the Exchange server and the troublesome messages will disappear.

My company's firewall enforces NTLMv2 proxy authentication, which kinda sucks for some Linux hosts since I can't pass that authentication directly on the command line. Maybe I'm dumb, but every command format I found didn't work. But this did work...
1. Install CNTLM package: apt-get install cntlm
2. Configure username/password in /etc/cntlm.conf.
3. Restart cntlm service: /etc/init.d/cntlm restart
4. Try this format: http_proxy='http://127.0.0.1:3128/' apt-get update
CNTLM does the authentication for you, so you can relax and think about more important things.
NOTES
* Enable remote hosts in cntlm.conf to allow other hosts to use this child proxy.

Make sure the partclone package is installed.
apt-get install partclone
Create an empty image file.
touch image-file.img
Restore the clonezilla files into the image file.
cat sda1.ext3.ptcl-img.gz.* | gzip -d -c | sudo partclone.restore -C -s - -O image-file.img
NOTES
* This is 3 commands on 1 line with pipes.
* Be sure to include the lone hyphen in the last command. That's not a typo!
Mount the image:
mount -o loop -t ext3 /folder-path/image-file.img /mnt
If you converted an NTFS partition, it probably won't mount. Try this...
Mount the image - NTFS:
ntfs-3g /folder-path/image-file.img /mnt
