    Re: How to protect Computer from Viruses and Malware

    What you can do to protect your computer against Viruses and Malware

    Install an antivirus program. By installing an antivirus program and keeping it updated, you can defend your computer from viruses. Antivirus programs look for viruses that try to access the e-mail, operating system or files. Every day new viruses are spread, so it is advisable to visit the website frequently for updates of the antivirus manufacturer. In most cases, antivirus programs are provided with annual subscriptions, which you can renew as needed. To find an antivirus program, please visit the Windows Vista Security Software Providers . Do not open email attachments. Many viruses are sent as attachments to e-mail messages and attachments are spread as soon as they open. It is best not to open attachments unless they are expected to file. Microsoft Outlook and Windows Mail help block potentially dangerous attachments. Keeping Windows updated. Periodically Microsoft releases special security updates that may be useful for computer security. These updates help prevent attacks from viruses and other computer by closing possible loopholes. Make sure that Windows receives these updates by turning on Automatic Updates in Windows. To find out how to do this, see Enable or disable automatic updating . Use a firewall. Windows Firewall or other similar alert you of any suspicious activity if a virus or worm tries to connect to your computer.

    First, and as obvious, we have installed an antivirus. There is already a lot of them and most can be downloaded online for free. Among the most reliable find AVG Anti-virus, Nod32 and Avast you can download. Once installed the virus on our computer, we can say that we are almost certain, though this is a utopia because we will never be 100% safe. The virus will not be an impenetrable shield; you also need help from us. What we can do to avoid viruses? Much...

    We update the antivirus, most of them already have a built for daily updated automatically, but you still need to be vigilant and check each program while you are doing. New viruses appear daily on the net and if we keep our software updated to saving the computer can become infected.

    In terms of our responsibilities, lack of attention can lead to inadvertently let a virus to enter our computer. This can occur, for example, opening an unknown file in our mail etc. That's why we must pay special attention to each attachment you open, and especially with the extensions. EXE,. COM,. PIF. BAT and others. Normally safe all graphics file (GIF, JPG, PNG) and music (MP3, WMA, WAV) but still this is not always so. Fortunately, most mail clients include antivirus service in charge of scanning the file before opening it, but if you use Outlook or Thunderbird is better to pay attention. If you do not know the sender, avoid open what you send, but this is not always safe because many viruses are auto-sent on behalf of the user and not even notice them. Thus the only solution is to pay attention, be suspicious of strange messages and files and scan them before opening

    Viruses have long been the scourge of the Internet. Moreover, they appear to be more and more sophisticated: where the 'old' viruses your computer did crash, they infect your computer and ensure they are such that your bank details will be passed on to criminals when you do not notice them. Do you feel computing, it is to protect your computer is always priority number one. What's the best approach, we list here. Probably do that now a lot of.

    Keep your computer safe from infections, you ensure that you have to start regular updates of the operating system (Windows) to install, it can also automatically expire. In addition, install decent antivirus software. Although none is perfect, walking according to Trend Micro and Kaspersky Security.nl leading the fight against malware.

    Prevention is not only trying to prevent viruses from entering our computer, but also involves safeguarding the information. Therefore it is advisable to make backups or backups of important files regularly, keeping them on CD, DVD or any other device. Thus, if the virus wiped out your hard drive or computer, we can stay a little easier knowing that we have copies of these files. Finally, although the current antivirus are continually reviewing each file to be opened and the program activities, you should perform a full scan of the computer each week or when we see fit, to make sure everything is clean and free of virus.
