Search the Internet to find a "new" virus. Tell me about the virus, what is does, and more importantly, how to remove it. Don't use technical terms, I can look that up myself. Tell me like you are telling your mother to watch out for it and once she got it, how to remove it.

Troj/Invo-Zip - This is a Trojan virus. A Trojan virus allows a hacker remote access to your computer system This is also Malware. Malware gets in and damages the computer without the computer owners approval or knowledge. This virus is sent in a spam email that claims to be an invoice. It comes as a zip file.

To remove:
1. Using Enterprise Console

You can remove Trojans over a network using Enterprise Console.
2. Sophos Anti-Virus for Windows, version 7

To remove a Trojan:

* Close down all programs.
* Go to Start|Programs|Sophos|Sophos Anti-Virus and run the 'Sophos Anti-Virus' program.
* In the 'Available scans' list, select the scan for which you want to enable removal, or use 'Setup a new scan' to scan your local disks. (Do not select a scheduled scan, as you will not be able to run this manually.)
* Click Edit|Configure this Scan.
* Select the Cleanup tab and select 'Automatically clean up items that contain virus/spyware'. Click Apply|OK.
* Click 'Save and Start' to save the scan, and run it immediately.
* At the end of the scan, click the link in 'Items passed to Quarantine' to open Quarantine manager.
* Select any items needing removal.
* From the 'Perform action' dropdown, select 'Delete'.
* Select 'Yes' or 'Yes to all' to delete files.
* Run another scan to ensure that the file has been removed.
* Click Edit|Configure this Scan.
* Select the Cleanup tab and deselect 'Automatically clean up items that contain virus/spyware'. Click Apply|OK.

If Sophos Anti-Virus cannot delete files because they are held open by the operating system, make a note of the names of the files, then do as follows.

1. Download an emergency copy of SAV32CLI. On an uninfected Windows computer, run this file to extract the contents into a SAV32CLI folder on a medium that can be write-protected. Copy the SAV32CLI folder produced onto a medium that can be write-protected. Add any relevant IDEs to this folder and write-protect the disk (on a CD/R or CD/RW close the session).
2. Restart the computer in Safe Mode. Go to Start|Shut Down. Select 'Restart' from the dropdown list and click 'OK'. Windows will restart. Press F8 when you see the following text at the bottom of the screen "For troubleshooting and advanced startup options for Windows 2000, press F8". In the Windows 2000 Advanced Options Menu, select the third option 'Safe Mode with Command Prompt'.
3. At the affected computer, place the CD in the CD drive (D: in this example). At the command prompt type

D:
to access the CD drive. Type:

CD SAV32CLI
Then type:

SAV32CLI -REMOVE -P=C:\LOGFILE.TXT
to remove the file.
4. Before leaving Safe Mode, edit any registry entries mentioned in the analysis recovery instructions. If problems persist, contact support.

3. Windows 95/98

To remove a Trojan:

* Check the threat analysis for details on the Trojan and its removal.
* Go to Start|Programs|Sophos Anti-Virus and run the Sophos Anti-Virus program.
* Select the Immediate tab.
* Go to Options|Configuration. Select the 'Disinfection' or the 'Action' tab, (according to what is displayed in your window) select 'Infected files', select 'Delete' then click 'OK'.
* Click the green 'scan' arrow, or the 'GO' button (as appropriate) to run the scan.
* Delete the files. Run another scan to check it has gone.
* Go back to Options|Configuration. Select the 'Disinfection' or the 'Action' tab, then deselect 'Infected files' and 'Delete'. Click 'OK'.
* Reboot and run a final scan to be certain it has gone.

If the Trojan cannot be removed because the files are held open by the operating system:

* Reboot the computer from a clean startup or system disk.
* Delete the file manually, or using the following DOS instructions:

You will need SWEEP for DOS on floppy disk. To do this, make a set of Emergency SAV disks.

* Check the threat analysis for details on the Trojan and its removal.
* Reboot your PC from a clean system disk, put the SWEEP for DOS disk in the floppy drive and at the A: prompt type:

SWEEP *: -REMOVEF

Pick a legislator, a governor, a vice president, a senator,a president, or someone in power and tell me where they stand on technology. Please site your references and write it in your own words.

I picked San Francisco Mayor Gavin Newsom. Mayor Newsom started “Open Data Policy” on the site Datasf.org. This is open data, participation source on an open website. This site will be an interaction between residents and agencies and will share infor. There is an interactive crime map with San Francisco Crimspotting. This is a link that take you to areas where there is crime and what the crime is.

He also supports EveryBlock. This is a breakdown of what neighborhoods are requesting from their government.

Mayor Newsom issued an “Open Data Executive Directive”. This asks that government be open and put anything that is not confidential on “Datasf.org” for all the public to see.

To me this technology will make sure that there is nothing hidden in the government (but of course, there still will be), but this is a good start. He is trying to bring in public partnering with government.

I've said that ME was a horrible operating system. Explain as to why it was such a bad OS and what some of the problems were. Also, tell us if you have had experience with it.

Windows ME was unstable and unreliable. It would freeze up and crash often. Some found it difficult to install and getting to to run correctly. It did not work well with the hardware and the software on your computer. Malware would reinstall with a system restore. System restore would use incorrect date stamps on the system restore. You could not trust the date stamp after Sept 8, 2001. Microsoft had to issue an update to fix this.

ME did not support MS Fax, QuickView, Active Directory and more because this release was mainly targeted to the home user.

Micrsoft released 3 Beta version during the development. It was released December 31, 2000 and support ended Dec 31 2006.

I remember having this, but at that time, I was just interested in basic computer fun. I remember installing ME and thinking this MUST be better, the packaging and commercials were so cool! And it was "first" upgrade and I thought I was so cool getting the latest and greatest!!!

What is Linux and who would use it? Would you? Keep in mind this is worth 10 points so it will be graded accordingly. Also, remember to use your own thoughts and ideas.

Linux is an operating system. It is installed on mobile phones to supercomputers, but basically used in servers. Per Linux.com, Linux does not need anti-virus protection because the user is very rarely logged into the root. The virus would have a hard time modifying the registry. "AVG Free for Linux" is designed for Linux and it's free, so it cant hurt.

Anyone would want to use Linux after you get used to it. Its an operating system that has no virus as of yet and very stable. You can use OpenOffice instead of MicroSoft Office,The Gimp instead of Photoshop, Foxfire instead of Internet Explorer, Thunderbird instead of Microsoft Outlook and MMMS Mplayer instead of Windows Media Player.

Microsoft is developing an embedded program for hand-held internet devices. As you surf the internet on your internet hand-held device there will be this little symbol showing by a words or picture. When you tap this, its like a hyperlink that will take you right to your word or picture.

I will add that the iPhone basically has this feature already. MS seems to be one step behind!

Do some research and find a cool multimedia device or software. Tell me about it and give me a web URL I can find out more information about it.


"cyberguys.com" (best place ever to shop if you are a computer geek!!)


The multimedia device that I would really find fun and handy for my office as we do not have laptops, we have desktops, would be a "Handwriting Recognition System"


This is a pen and a "reader" that takes what you write, on any type of paper, write all your notes page after page and you can upload to your computer as a text file. This can hold up to 50 pages of info. It uses regular ink so that you save money on special ink and you can use any kind of paper unlike some expensive brands that need a specific "Tablet".


This comes with handwriting recognition software, extra regular ink, 17 languages, USB cable and 2 batteries.


This does not work with a Mac. This will work for Windows 2000/XP/Vista and works with Office XP/2003/2007. Cyberguys.com sells this for $73.39


This is sold by IOGEAR. There is more specific information on the IOGEAR website at www.iogear.com, but don't buy it there as its $99.95 on that site.

This is just one multimedia toy in this catalog that I love. My other favs are power strip liberators and USB hubs.

Chapter 8, page 359 "hands-on Project" Project 8-1 Use the internet:

What is the price of the internal floppy drive? You can get an internal for about $25 at Tigerdirect.com.

What kind of connections do the external floppy disk drives uses? the particular one I looked at used a 34 pin floppy connector.

What is the price of an external floppy drive? You can get an external floppy drive for about $20 at TigerDirect.com.

Why do you think external drives cost more than internal drives? Because they need to be self sufficient and they have a case.

What are the advantages of external drives? Handy to carry around.
Internal Drives - Stability as far as cant be dropped, you cant loose them and you can transfer data to other machines carrying a floppy.

In addition, define these terms:

*******I need help with the layman's terms for Low level formatting and IDE...

DMA - sends data from drives to memory with out going through the CPU. DMA has 7 speeds 0-6

low level formatting - I read this and still cant tell you in my own words what this is.


SATA - A serial ATA has a bit following the next. They come in 2 cables, eternal and internal. They are thin so that airflow in the case is not compromised. External SATA are 6 times faster that USB or Firewire. They are more costly than a parallel cable, because they are new. They are expected to be for high-performance large drives. Several drives now use the SATA.

ATA - This is what controls speeds and transfer methods of drives and how they work with computers. There are 2 kinds, serial and parallel.

IDE - Technology used internally by a harddrive. (taken from the book. I still cant figure this is my terms)

What is Second Life?  Could it be used for anything useful?  How could businesses use it?  How could education use it? Would you use it?  Why or why not?  Again, make me think you know what you are talking about and make it more than a sentence or two.  


Second Life is an online community.

Businesses could use this for advertisement and free downloads.

Education could use this to post ads for Universities and create possible “classes” that the avatars can attend. They could be free general classes or tutorials or create small paid classes that you would pay through the dollars you can earn on this game.

I signed on and created a person. Not sure I would use this as I’ve been “walking” around for a while now and there is no easy explanation of what I am doing. I'm an instant gratification person and this site is not it. I had a guy walk by and say something in another language to me and they he through up his hands when I didn't answer.

I'm not familiar with this site as of yet. There is so much exploration. I think sites like this are a little un-nerving for me as they are interactive with strangers. I’m going to explore and read up on this site a bit more.

There are many new innovative tools for people with disabilities.  Find two, describe what they are, who they might help, how they work, and if possible, how much do they cost?  Please make it more than one or two sentences....it is worth 10 points so I expect a little effort this time.

Mac OS X has a built in screen reading. This is a voice over program that tell you via the speaker what is going on, on your screen. It will tell you windows, menus, and more. This voice over program will let you control your Mac with your keyboard. Mac has braille display or you can use its multi touch trackpad. A Mac runs from $1000 to $3-4000

Another one of my favorites is Dragon Naturally Speaking. It will type as you speak, this helps visual impaired with letters, emails and several other programs on your computer It is very accurate and faster than typing. Dragon ranges from $99 standard to professional at $900.

Then there is my ultimate program. Its called Signtel Interpreter. This is for the deaf, hard of hearing, blind-deaf or visually impaired. This program translates speech and text to sign language. This is a program you load onto your computer. Laptops mostly. This program will run you $4,900.00 (text only) to text and voice for $5,400.00. Laptops can be added for another couple thousand.

Processor Frequency
The processor frequency is how fast that internal processor beats per second. It beats more times in one second that a heart in a lifetime!

Word Size
The number of bits that a processor can handle at one time.

Overclocking
Overclocking is were you chance the processor speed to run faster than it was meant to go. It takes more work for the processor but can speed up games and applications. Overclocking can also speed up older processors so you don’t need a new faster one.

Data Path
The number of bits that goes in and out of the processor.

SRAM
Stands for static ram. This keeps the information on the computer until it the computer shuts down. This does not need to be refreshed. SRAM is more costly that regular memory.

Primary Cache
Primary Cache is the fastest memory on a PC. It's in the processor and a very small amount, not more than 64kb. The Primary cache runs the same speed as the processor.

External Cache
This is external memory that is not part of the processor, but may be in the processor. External cache is also called Level 2 (L2)

Memory Cache
Memory cache is RAM and keeps all your data in its memory so the computer doesn't have to always go back and look for it. Memory cache is also called Level 1 (L1)

Power Supply for Mom

http://www.newegg.com/Product/Product.aspx?Item=N82E16817152028

Mom, you need to go to newegg.com to buy this cool power supply for Dad.

It costs $39.89.

This has a 530W PSU which is the electrial power. A normal computer is from 200 to 600W. This should be great to run all Dad's stuff.

This delivers 28A on the +3.3V rail and 34A on the +5V rail plus 20A and 17A on the two 12V. This means that Dad's monitor that needs about 2A and his printer, about 2A and his CD drives that need about 1A and all his other drives will not even come close to using the 28 amps that this will provide.

This is an ATX so it will fit in Dad's common form factor machine.

The fan has a "Blue Glowing LED Fan", and I think that means is the fan is glowing, there is a charge in there, so tell him to be careful and not get shocked by the current that may still be in the power supply.

The 100 - 240 V is good, so incase of spikes, it can handle the extra volts.

I dont see an energy star rating, but it it states it delivers up to 80% efficiency. This could even save you $$ on your electric bill.

I hope this helps you! Have a great time in Bora Bora!!! Linda

What Does the Research Say About Technology's Impact on Education?

I read all the links on http://www.ncrel.org/sdrs/areas/te0cont.htm.

Research states that the Internet has become a vital part of learning. Students are researching more for their homework. Teachers need to monitor more due to “copying” from the internet.

Research shows that students that write down their homework retain more than copying and pasting from the internet.

There were so many research sites, but I noticed that very few gave actual grade statistics.

Students can get tutorials on line for science classes and it is much more effective than sitting and watching an outdated movie.

I think schools should stop buying books and start buying inexpensive laptops for students. I think the entire educational system should be evaluated as the technology grows. Grade schools are teaching out of date info because they can’t afford new books.

I do worry about children not learning the basics because of technology. Spelling is automatically correct, as is grammar. Math problems are solved in seconds. Students are lacking imagination.

My niece, who is 12, sends me “updates” on Facebook. I can’t understand half the words she is using the other half are spelled incorrectly.

Students may have more access to learning, but they are sadly under socialized.
