6. Download The Operative System's Actualizations

It is substantial, to get your protection to the maximum against eventual virus attacks, to download this actualizations; because what most worm Trojans seek are commonly found “security holes” in most Microsoft products. For these, the company constantly offers “critical” actualizations which we can download, and for those who are a bit lazy to look for them in the internet, Windows has an option for them to download automatically.

7. Be Careful With The Files You Receive In Your e-Mail

When we receive a new mail, it is highly recommended to virus scan it, even if you know the remittent. Most users do not even know that their computers are infected, and may be sending you a corrupted file by accident.

8. Another Entrance Gateway, Chat

In most chat rooms it's really common to send any kind of files, via a DDC system. If you get one you never requested, or from an unknown source, NEVER accept it, even if it seems really interesting.

9. Other Tips

Pay special attention to archives which may grow in size without any apparent reason. Or if you get strange Windows notes. Try not to download stuff from web pages you may consider unsafe.

10. And Of Course, Update Your Antivirus

Nowadays there are quite good either free or paid antivirus. In both cases they update automatically, so we all have the parches for the dangerous Mydoom y mentioned in the first part of the article.

If you haven't read the first part, brush up on tips one to five.

So in counterpart I am writing this article in order to try to advice other computer users who did not know about it.

And publish 10 obvious but really important tips that everyone with a computer must follow. So if you haven't been infected yet, you should read the next:

  1. Be Careful With VBS Archives

    Do not open files with the extension VBS (Visual Basic Script, a language which permits to execute routines in the PC) unless you are completely sure that that mail comes from a trustable person, who doesn't want to harm your computer.

  2. Do Not Hide Program Extensions

    All Windows operative systems hide commonly known program extensions in windows explorer. This characteristic can be used by virus designers and hakers to hide a program as if it were one with a different extension.

  3. Change Windows Explorer Security Form “Minimum” to “Medium”

    To change this you must go to “Tools”, “Internet Options”, and “Security”. After that you may choose the one you like. I recommend using the option to personalize and set it to mid or high, depending on the risk to which you consider you may stand up to.

  4. Install a Good Firewall

    This is really important. You may download a free one from the internet, or just configure the one from your operative system (better if you have windows XP).

  5. Make Security Copies

    A way is to upload most important archives to internet. There are web pages such as Rapidshare, Megaupload, or File Factory to which you may upload important stuff. In this way you may clear your hard disk without loosing info. Of course there are other ways, such as making backup copies in CDs, DVDs, ZIP drives or pen drives.

But sometimes when we install a program, it changes “Windows” settings and the Recycle Bin disappears. If this happened to you, don't worry, because there is an easy way to get back the Recycle Bin.

1. Press START and select RUN. In the new open window enter gpedit.msc.

2. In the new window go to User Configuration> Administrative Templates>Desktop. Than find “Remove Recycle Bin icon from desktop” and double click on it.

3. After that, tick on the “Disabled” and press OK. Now refresh your desktop by pressing F5.
