Is it safe to keep your computer on for a long while?
Mine is on for 24 hours straight, but i turn it off eventually Turning your computer off and on repeatedly actually causes more "wear and tear" on it than leaving it run continuously. It's still a good idea to reboot it periodically. One reason is to clear up any memory that might not have been fully released by the application that last used it. A buildup of unreleased memory will deteriorate your computer's performance over time. I usually reboot mine every 2 weeks or so. Also be sure and periodically run scandisk and defragmenter on your system to keep it in top shape.
Can a virus affect the ROM of a computer?
It shouldn't affect the ROM - ROM stands for Read Only Memory. The data in the ROM was written at the manufacturing stage of the computer, and viruses shouldn't be able to affect it.
If you have antivirus software can you still get viruses?
yes and actually the 'so called' "Anti-virus 2008" software is a virus desguised as an anti-virus software opens a backdoor that downloads other virus onto the system. The best thing (the only thing actually) you can do is then download the trial or buy the Norton 2008 package off their website which will fully take ALL virues out gaureenteed by me (jk). So yea..
Also, there's a virus called "ALPHA ANTIVIRUS"and my computer got it off of facebook and I had to look it up to delete it.
And again there is another virus called Antivirus7, it tellls you too give it information and to buy it but really its someone trying to take all your info. If you seem too have it on your computer i advise you too take it off. Another thing to look out for is things that are unusual.. NORTON DOES GIVE VIRUSES. Norton does not help at all and you have to pay for it which is the WORST PART OF ALL. please be carful .
I recommend FIREWALL, and more
How do you remove internet security 2010?
Internet Security 2010 is a fake antivirus that hijacks your system starting from boot up, launches popups that display fake warnings of fictitious viruses, and asks you to purchase a so-called licensed program. Its real purpose is to entice you to purchase a registered version of Internet Security 2010 giving you the false perception that you've eliminated the problem after you have already paid.
There is a quick solution to get rid of Internet Security 2010 before it does more damage to your system. You will have to run a scan to check where the infection and remove this virus automatically. You can also do the removal manually if you wish.
Where and when first computer virus was created?
"The first PC virus in the wild was a boot sector virus dubbed (c)Brain[7], created in 1986 by the Farooq Alvi Brothers, operating out of Lahore, Pakistan, reportedly to deter piracy of the software they had written[citation needed]. However, analysts have claimed that the Ashar virus, a variant of Brain, possibly predated it based on code within the virus" - Wikipedia

What is one of the main impacts of technology in the the information age?
There was a massive impact on the human population after the Information era. People became much more aware of their surroundings and actions for example.
Software has become the key element in the evolution of computer based system and products. Over the past 60 years, software has evolved from a specialized problem solving and information analysis tool to an industry in itself. But early programming culture and history have created a set of problem that persist even today. Software has become the limiting factor in the continuing evolution of computer based systems. Software is composed of programs, data, and documents. Each of these items comprises a configuration that is created as part of the software engineering process. The intension of software engineering is to provide a framework for building software with higher quality.
What is the use of pop-up blocker?

Is other protection needed against harmful code besides installing anti-malware software?
True. Install updates from Microsoft and enable your fire wall.
This is Rogue Security Software. Rogue security software can install itself onto any PC or laptop, just from a click to a misleading website. There are hundereds of rogue security applications that are lurking to steal your credit card number.
Rogue security software will usually download itself via. a fake scan flash animation. It will give the user the option to download the program. No matter what choice you pick, it will download automatically. If you see a popup message saying something like "Your PC is in danger. Click Yes to remove found threats", follow these steps from this software to not download on your computer BEFORE YOU CLICK ANYTHING:
1) Press Ctrl+Shift+Esc.
2) Task Manager will open. Go to the processes tab.
3) Terminate iexplore.exe, safari.exe, chrome.exe, or firefox.exe (Depending on the browser you are using) and click Yes. iexplore.exe = Internet Explorer.
Also, this type of "antivirus" software is fake. It will generate misleading scan results to lure you into buying the product. When you buy the product, these companies behind their servers may take more money off your credit card than how much you paid for. If you purchased the program before reading this, please call your credit card company as soon as possible!!
These programs also mess with your Windows HOSTS File, which, if edited, will make your Google searches more harder, as you will be redirected to other websites if you click on the first 2-3 search results. Also, they will mess with your Proxy server settings, as this will disable you from accessing the Internet. In addition, such programs may block access to any program such as Windows Task Manager, Windows Security, Downloaded programs, and antivirus programs, etc.
So, that's about it for Rogue Security software.

What are the risks of opening up an email attachments?
The risk is the spread of malware. Malware is anything that affects the functionability of your system or executes commands that are not wanted by the user. You can get anything from viruses to trojans to worms, spyware, adware, grayware. The best way to help avoid these dangerous attachments is to really chose your email account wisely. Yahoo is the best free email because it scans all of the files you want to send as attachments and before you open them it scans them again. This helps to stop the spread of email. The next is to use common sense. As your self am I suppose to get this email. also ask your self these questions. was I expecting it, do I know the sender, does me getting it help me in any way and why would I need the email and the attachment
Email viruses and worms are common. If you've not received one, chances are you will. Here are steps you can use to help you decide what to do with every email message with an attachment that you receive. You should only read a message that passes all of these tests.
- The Know test: Is the email from someone that you know?
- The Received test: Have you received email from this sender before?
- The Expect test: Were you expecting email with an attachment from this sender?
- The Sense test: Does email from the sender with the contents as described in the Subject line and the name of the attachment(s) make sense? For example, would you expect the sender - let's say your Mother - to send you an email message with the Subject line "Here you have, ;o)" that contains a message with attachment - let's say AnnaKournikova.jpg.vbs? A message like that probably doesn't make sense. In fact, it happens to be an instance of the Anna Kournikova worm, and reading it can damage your system.
- The Virus test: Does this email contain a virus? To determine this, you need to install and use an anti-virus program. That task is described in Task 1 - Install and Use Anti-Virus Programs of "Home Computer Security."
You should apply these tests - KRESV - to every piece of email with an attachment that you receive. If any test fails, toss that email. If they all pass, then you still need to exercise care and watch for unexpected results as you read it.
What do you do after you install virus scan software?

# Do a disk clean up. click start>all programs>accessories>system tools> disk cleanup. # Defragment your drive. click start>all programs>accessories>system tools> disk defragmenter. #
Which ways can a virus inject itself into its target?
Computer viruses are either 'attached' to an email - or hidden on a CD-ROM or floppy disk. When someone opens the email or inserts a disk without scanning it - the virus has a chance to infect the new computer.
Yes.

Who designed the first computer?
The first computer was designed by Charles Babbage in 1837. It was called the "Analytical Engine". The design was mechanical and Babbage never got to build his machine. It would have operated more like a large mechanical calculator than a computer as we know it.
More recent computers were designed during the Second World War to assist the British in their code breaking efforts, these were either mechanical or electrical in operation.
More modern computers developed all through the 1950's and 1960's, however these were large, bulky machines and operated on systems of vacuum tubes; this used large amounts of electricity, generated large amounts of heat and needed large rooms to be constructed in. The price of operating and maintaining them meant that only the military, universities and insurance companies could afford them.
In the 1970's and 1980's smaller computers were developed using transistor and then Integrated Circuit technologies allowing them to become smaller and produced in larger numbers; this gave rise to consumer products like the Apple 2E, Commodore 64 and ZX81 and ZX Spectrum. These products were refined and updated into the PC's, Laptops and Tablets that we use today.
