Computer Maintenance

Hi!
You may not realize it, but your computer and your car have something in common: they both need regular maintenance. No, you don't need to change your computer's oil. But you should be updating your software, keeping your antivirus subscription up to date, and checking for spyware. Read on to learn what you can do to help improve your computer's security.


Getting started

Here are some basics maintenance tasks you can do today to start improving your computer's security. Be sure you make these part of your ongoing maintenance as well.

* Sign up for software update e-mail notices. Many software companies will send you e-mail whenever a software update is available. This is particularly important for your operating system (e.g., Microsoft VV!|VD0VV$® or Macintosh), your antivirus program, and your firewall.
* Register your software. If you still have registration forms for existing software, send them in. And be sure to register new software in the future. This is another way for the software manufacturer to alert you when new updates are available.
* Install software updates immediately.
When you get an update notice, download the update immediately and install it. (Remember, downloading and installing are two separate tasks.)
An ounce of prevention

A few simple steps will help you keep your files safe and clean.

* Step 1: Update your software
* Step 2: Backup your files
* Step 3: Use antivirus software and keep it updated
* Step 4: Change your passwords


Developing ongoing maintenance practices

Now that you've done some ground work, it's time to start moving into longer term maintenance tasks. These are all tasks that you should do today (or as soon as possible) to get started. But for best results, make these a part of a regular maintenance schedule. We recommend setting aside time each week to help keep your computer secure.

* Back up your files. Backing up your files simply means creating a copy of your computer files that you can use in the event the originals are lost. (Accidents can happen.) To learn more read our tips for backing up information.


* Scan your files with up to date antivirus software. Use your antivirus scan tool regularly to search for potential computer viruses and worms. Also, check your antivirus program's user manual to see if you can schedule an automatic scan of your computer. To learn more, read our tips for reducing your virus risk
.
* Change your passwords. Using the same password increases the odds that someone else will discover it. Change all of your passwords regularly (we recommend monthly) to reduce your risk. Also, choose your passwords carefully. To learn more, read our tips for creating stronger passwords.

Making a schedule

One of the best ways to help protect your computer is to perform maintenance regularly. To help you keep track, we suggest making a regular "appointment" with your computer. Treat it like you would any other appointment. Record it in your datebook or online calendar, and if you cannot make it, reschedule. Remember, you are not only helping to improve your computer, you are also helping to protect your personal information.

Double Click on the following settings and put in the numbers below - for the true / false booleans, they will change when you double click.

network.http.max-connections – 48
network.http.max-connections-per-server – 16
network.http.max-persistent-connections-per-proxy – 8
network.http.max-persistent-connections-per-server – 4
network.http.pipelining – true

Microsoft acts to avoid Windows bluescreen .............. repeat.

Microsoft took steps Tuesday to avoid repeating the debacle two months ago that left Windows XP users staring at the notorious "Blue Screen of Death" error message after they applied a patch.

In February, a security update that fixed two flaws in the Windows kernel -- the operating system's most important component -- wreaked havoc when it was applied by users, who almost immediately flooded Microsoft's support forum with reports of crippled computers.

As the number of reports grew, Microsoft first stopped automatically serving the MS10-015 update, then confirmed that a rootkit caused the crashes. Only PCs that had been previously infected with the Alureon rootkit were incapacitated, Microsoft's investigation found.

Microsoft restarted distribution of the update only after it had come up with a way to block rootkit-infected PCs from receiving the patches. "If detection logic included in Automatic Update discovers abnormal conditions in certain operating system file configurations, the update will fail and customers will be presented with an error message that offers alternative support options," said Jerry Bryant, general manager with the Microsoft Security Response Team, in early March.

MS10-021, one of the 11 updates issued yesterday as part of Microsoft's monthly Patch Tuesday cycle, also fixed flaws in the Windows kernel. But Microsoft is hoping that this month's update won't trigger a repeat Blue Screen of Death.

"This security update includes package detection logic that prevents the installation of the security update if certain abnormal conditions exist on 32-bit systems," stated the MS10-021 bulletin. "These abnormal conditions on a system could be the result of an infection with a computer virus that modifies some operating system files, which renders the infected computer incompatible with the kernel update."

One security expert applauded the move.

"I give Microsoft a big tip of the hat for not taking [the February incident] as a one-off," said Jason Miller, data and security team manager at network compliance and security vendor Shavlik Technologies. "The kernel is something that if something goes bad, that's not good. Patching the kernel is not like patching a media player."

Microsoft obviously learned a lesson. Even though the February update crashed a relatively small number of PCs, the problem actually affected many more, he argued. "It may have affected just a few people, but it scared almost everyone into not patching," Miller said.
