Computer Viruses

The serial number would either be on the back of the CD case or within the documentation that came with your software when you purchased it. You will know it is the serial number because it is a mix of numbers and/or letters separated by dashes, usually around 20 characters long.

You can't install this software without the serial number. Follow the on screen instructions during installation. One of the instructions will come up asking you to enter the serial number - put it into the white boxes - and the installation will continue. You can't use the software without installing it.

Contact costumer services at Norton (by mail, email, or phone). They will probably need proof of purchase such as original receipt, bar code on package, or some other form of identification. They will instruct you on what is needed and will then give you a new serial number if necessary.

Downloading proprietary software is illegal (except for trials). This is called piracy. Using serial numbers that you did not purchase is also illegal, even if you purchased the software and lost your serial number (see above for obtaining a new one in this case). It is also illegal to use key generators (keygens) which provide serial numbers as well as cracks to bypass expired time trials or entering a serial number and no-CD cracks which enable you to use the software without the original purchased CD for the software.

WikiAnswers will not provide serial numbers or links to serial numbers. We will also not provide information or links on where to obtain pirated software, serial numbers, keygens, or cracks. If you are caught doing any of these, you may be blocked from using WikiAnswers as well as reported to the proper officials and/or the company who created the software.

Note: This is a catch-all question. Neither it nor its alternatives should be deleted or removed. It should also remain protected so that illegal information cannot be posted.

I have gotten a virus after using websites. Some helpful tips include:

• Be aware of the web extension - a 2 letter extension indicates a country abbreviation - be aware of using webs originating in countries where spam, viruses, and hacking are well known problems
• Read reputable web forums about computing. They often post warnings about particular problems in countries where spam, viruses, and hacking are well known.
• Use well-known websites with high reputations.
• Avoid clicking on Advertisements or Links for websites you do not know.
• If an Ad or Link looks interesting, Google the Company's Name to see if other users posted in forums about problems.
• Use a good Antivirus Program. Many FREE programs have surfing protection that will alert you to Sites that might harm your computer. One good Free AV is AVG -- research it and decide.
• Do NOT open or click links in Email, even from Friends.
• Avoid clicking on Video Links from email. Go to youtube directly and search for the video.
• Be cautious about what you download.
• Know which file extensions are executable - which ones execute action - on your computer. Avoid exe file extensions.
• Run antivirus on anything you download, even pictures, songs, videos, Word and other text files.
• Run antivirus every week, and keep it updated.
• Malawarebytes (free) deletes malware and spyware.
• Spybot Search and Destroy (Free) also finds malware and spyware.
• Be proactive to keep your computer and web surfing free from viruses, malware, and spyware.
• If your computer 'catches' a virus, don't ignore it. Fix it quickly.

Antivirus software are computer programs that attempt to identify, neutralize or eliminate malicious software. The term "antivirus" is used because the earliest examples were designed exclusively to combat computer viruses; however most modern antivirus software is now designed to combat a wide range of threats, including worms, phishing attacks, rootkits, Trojan horses and other malware.
