3 Preventing transmission of the virus via USB disk

Local viruses have one peculiarity that is rarely found on foreign-made computer pests. A Virus or worm out usually make use of the internet for spreading. Another case with a local virus. Its creator is often designed so that the virus can reproduce through the mediation of the usb disk, be it a flash disk or portable hard disk. This may be because in Indonesia are generally data exchange via a portable medium much easier to do.

I myself had a chance to get acquainted with the two types of viruses that spread via the local usb disk. Fortunately both are relatively tame, unlike the famous ferocious virus Brontok. And more lucky again two types of virus that I encountered on other people's computers.
Both have the same transmission method: via flash/portable disk. The mode takes also the same, i.e., by leveraging the Windows autorun feature.

Autorun feature (or autoplay) is actually intended for medium such as CD-ROM or DVD, so that the computer can directly execute the program (usually installer) in the optical disc when inserted. Autorun feature is enabled by the computer infected with Autorun.inf file with writeINF to the flash disk. These files are hidden (hidden) contrived and converted its status becomes read-only.

File AUTORUN.INF contains commands to execute other files in the form of programs that are also entered by computer contracting. This Program can be written in Visual Basic (this means we can read your own code), or in the form of binary executable files. The second file is in charge of infecting other computers. Then when the USB disk is first plugged it into the USB slot, and the computer detects the file AUTORUN.INF he will read it and then run the command run the program penular. Of the two events I encountered an antivirus program that is installed does not warn the existence of viruses in the flash disk.
 

Remove and prevent virus 

Treat your computer already contracted the virus rather troublesome. Fortunately cleared the USB disk and ward off penjalarannya on a computer that is still clean quite easily. In both cases I found this transmission mechanism when using a USB disk on a computer that is running a non-Windows operating system (in this case, Fedora 7).

So far Fedora 7 and other distributions of Linux (and Mac OS) are immune from the virus Windows. Because it is quite safe to use non-Windows systems for cleaning the virus from autorun feature that utilizes the USB disk. Open the AUTORUN.INF file..INF FILE using a text editor, and then from there find the file which will be executed automatically. Find and delete these files. The last delete Autorun.inf file too.

Penangkalan this virus on my computer Windows is quite clear: turn off the autorun feature. This will not fully guarantee transmission through computer immune from USB disk, but it will ward off But how?
Users of Windows XP can download Tweak UI, which is one of Microsoft's Power Toys utility from http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx

Click TweakUIPowerToySetup file to install the utility. When you're done launches Tweak UI. In the left pane of the application window, select My Computer, and then select Types. Clear the box next to Enable Autoplay for removable drives, and then click Apply. If you want you can also disable the option Enable Autoplay for CD and DVD drives.4.5

0 Computer Tips - Top 10 computer security tips

Top 10 computer security tips :

1. Use "anti-virus software" and keep it up to date.

Make sure you have anti-virus software on your computer! Anti-virus software is designed to protect you and your computer against known viruses so you don't have to worry. But with new viruses emerging daily, anti-virus programs need regular updates, like annual flu shots, to recognize these new viruses. Be sure to update your anti-virus software regularly! The more often you keep it updated, say once a week, the better. Check with the web site of your anti-virus software company to see some sample descriptions of viruses and to get regular updates for your software. Stop viruses in their tracks!

2. Don't open e-mails or attachments from unknown sources.

Be suspicious of any unexpected e-mail attachments even if they appear to be from someone you know. A simple rule of thumb is that if you don't know the person who is sending you an e-mail, be very careful about opening the e-mail and any file attached to it. Should you receive a suspicious e-mail, the best thing to do is to delete the entire message, including any attachment. . If you are determined to open a file from an unknown source, save it first and run your virus checker on that file, but also understand that there is still a risk. If the mail appears to be from someone you know, still treat it with caution if it has a suspicious subject line (e.g. "Iloveyou" or "Anna Kounikova") or if it ortherwise seems suspicious (e.g., it was sent in the middle of the night). Also be careful if you receive many copies of the same message from either known or unknown sources. Finally, remember that even friends and family may accidentally send you a virus or the e-mail may have been sent from their machines without their knowledge. Such was the case with the "I Love You" virus that spread to millions of people in 2001. When in doubt, delete! If you receive an e-mail from a trusted vendor or organization, be careful of phishing, a high-tech scam used to deceive consumers into providing personal data, including credit card numbers, etc. For information about "phishing" go to the FTC document titiled "How Not to Get Hooked By a Phishing Scam", http://www.ftc.gov/bcp/conline/pubs/alerts/phishingalrt.pdf. The best way to make sure you're dealing with a merchant you trust, and not a fraudster, is to initiate the contact yourself. Type the merchant's address into your Internet browser instead of clicking on a link in an e-mail.

 3. Protect your computer from Internet intruders - use "firewalls."

Equip your computer with a firewall! Firewalls create a protective wall between your computer and the outside world. They come in two forms, software firewalls that run on your personal computer and hardware firewalls that protect a number of computers at the same time. They work by filtering out unauthorized or potentially dangerous types of data from the Internet, while still allowing other (good) data to reach your computer. Firewalls also ensure that unauthorized persons can't gain access to your computer while you're connected to the Internet. You can find firewall hardware and software at most computer stores and in some operating systems. Don't let intruders in!

 4. Regularly download security updates and "patches" for operating systems and other software.

Most major software companies today release updates and patches to close newly discovered vulnerabilities in their software. Sometimes bugs are discovered in a program that may allow a criminal hacker to attack your computer. Before most of these attacks occur, the software companies or vendors create free patches for you that they post on their web sites. You need to be sure you download and install the patches! Check your software vendors' web sites regularly for new security patches or use the automated patching features that some companies offer. Ensure that you are getting patches from the correct patch update site. Many systems have been compromised this past year by installing patches obtained from bogus update sites or e-mails that appear to be from a vendor that provides links to those bogus sites. If you don't have the time to do the work yourself, download and install a utility program to do it for you. There are available software programs that can perform this task for you. Stay informed!

 5. Use hard-to-guess passwords.

Mix upper case, lower case, numbers, or other characters not easy to find in a dictionary, and make sure they are at least eight characters long. Passwords will only keep outsiders out if they are difficult to guess! Don't share your password, and don't use the same password in more than one place. If someone should happen to guess one of your passwords, you don't want them to be able to use it in other places. The golden rules of passwords are:

• A password should have a minimum of 8 characters, be as meaningless as possible, and use uppercase letters, lowercase letters, symbols and numbers, e.g., xk2&LP97.
• Change passwords regularly, at least every 90 days.
• Do not give out your password to anyone! For enhanced security, use some form of two-factor authentication. Two-factor authentication is a way to gain access by combining something you know (PIN) with something you have (token or smart card).

6. Back-up your computer data on disks or CDs regularly.

Experienced computer users know that there are two types of people: those who have already lost data and those who are going to experience the pain of losing data in the future. Back up small amounts of data on floppy disks and larger amounts on CDs. If you have access to a network, save copies of your data on another computer in the network. Many people make weekly backups of all their important data. And make sure you have your original software start-up disks handy and available in the event your computer system files get damaged. Be prepared!

7. Don't share access to your computers with strangers.

Learn about file sharing risks. Your computer operating system may allow other computers on a network, including the Internet, to access the hard-drive of your computer in order to "share files". This ability to share files can be used to infect your computer with a virus or look at the files on your computer if you don't pay close attention. So, unless you really need this ability, make sure you turn off file-sharing. Check your operating system and your other program help files to learn how to disable file sharing. Don't share access to your computer with strangers!

 8. Disconnect from the Internet when not in use.

Remember that the Digital Highway is a two-way road. You send and receive information on it. Disconnecting your computer from the Internet when you're not online lessens the chance that someone will be able to access your computer. And if you haven't kept your anti-virus software up-to-date, or don't have a firewall in place, someone could infect your computer or use it to harm someone else on the Internet. and help protect others: disconnect!

9. Check your security on a regular basis.

When you change your clocks for daylight-savings time, reevaluate your computer security. The programs and operating system on your computer have many valuable features that make your life easier, but can also leave you vulnerable to hackers and viruses. You should evaluate your computer security at least twice a year - do it when you change the clocks for daylight-savings! Look at the settings on applications that you have on your computer. Your browser software, for example, typically has a security setting in its preferences area. Check what settings you have and make sure you have the security level appropriate for you. Set a high bar for yourself!

10. Make sure your family members and/or your employees know what to do if your computer becomes infected.

It's important that everyone who uses a computer be aware of proper security practices. People should know how to update virus protection software, how to download security patches from software vendors and how to create a proper password. Make sure they know these tips too!4.5
