Two Very Important Computer Alerts that you may not have seen: 1) on Windows XP and 2) a New Computer Virus, "Cryptolocker". I am posting links to both of these diaries in case you missed these alerts. FOREWARNED IS FOREARMED.
1) XP USERS BEWARE: Microsoft will no longer support Windows XP after April 8.
If you use Windows XP, see this excellent diary by Hey338Too with all the information you need, Windows XP - Less Than One Month Remains of Microsoft Support
As Hey338Too warns in the comment thread:
From what I've read, hackers are licking their chops and have been waiting for this for at least a year.
2) A warning is also circulating about the "Cryptolocker" virus, which is really an extortion racket, that would be a good idea to avoid. Putting it mildly. The hackers put a lock on your computer and then demand payment in Bitcoins to unlock it. Where is the NSA when you need them?
For more information on it, see the comment thread and links in:
Alert: New Computer Virus: "Cryptolocker"
