Hints on Computer Viruses

Recently multiple computer viruses caused major disruptions to the campus network. In addition to the risk of damage to your own computer and your personal data, infected computers are now frequently a tool for spammers to send junk email without detection and for professional criminals to steal confidential information for such crimes as identity theft. Here's how to protect your computer from viruses and how to cure it if it does get infected. Just what is a computer virus? It is a piece of software designed to surreptitiously enter your computer system and infect your files. Typically, a virus will replicate itself and try to infect as many files and systems as possible. Most viruses hide on removable media, such as Zip or floppy disks, in email attachments (not plain text messages alone), or on the Internet. If your system is infected and you save a file to a disk, you will probably infect the disk and any system that uses the disk.

Viruses can be written into almost any type of file, so you need to be careful when you add software to your system. Viruses have been accidentally included in licensed, shrink-wrapped software, but you are usually safe when installing legally purchased software obtained through normal channels.
A common myth is that viruses can be passed into your system only through executable program files or applications. Viruses can easily spread to your system from the Internet, bulletin boards, and email attachments.

The best way to keep viruses off your PC is to install antivirus software. The Downstate Network Technology Group help desk <http://uhweb1.hscbklyn.edu/netgrp/> provides antivirus software free of charge to students, staff and faculty which can be downloaded from their website. This software is for use on the campus with campus computers only. It will automatically download and install updates with information on the latest viruses. New viruses are released all the time and antivirus programs are only as good as their database of virus definitions. Your system will be checked for known viruses, incoming files will be scanned, and you will be warned you any infected files are let in. When you are not on the campus or are not using a campus computer,  the  Network Technology Group  recommends antivirus software from McAfee <http://www.mcafee.com/> or Symantec <http://www.symantec.com/nav/nav_9xnt/>.

It is also important that you download the latest security patches for your operating system and applications from your software vendors. Microsoft lets you do this automatically with the Windows Update feature.Once you've determined that all the files in your system are virus-free, you should do a complete backup of your system. This will allow you to restore clean copies of your files if you get infected thereafter.

Most viruses spread by email attachments and it's more than likely that an email attachment that contains a virus will come from a friend. Before you open attachments or downloaded files, scan them with your antivirus program. Also examine its file extension. Be very wary of any attachment with an extra extension, such as "happyfun.jpg.vbs."

Danger signs that may indicate your computer is infected – even if you antivirus software has not found a virus – include:

Unusual messages or displays on your monitor.

Unusual sounds or music played at random times.

Your system has less available memory than it should.

A disk or volume name has been changed.

Programs or files are suddenly missing.

Unknown programs or files have been created.

Some of your files become corrupted or suddenly don't work properly.Another way you can detect viruses is by monitoring the byte size of programs installed on your hard drive, particularly of .exe and .com files. If you notice unexplained changes in file sizes, this is a good indication that your system has become infected.
Here's what to do if you think your PC is infected.

1. Use your antivirus software Scan your hard drive, disk drives, and all files downloaded to your system, including email attachments. In some cases infected files can be "cleaned" by your virus protection software. In others, the files will have to be discarded or quarantined.

2. Disconnect.  Some viruses propagate across networks. It's a good idea to unplug your network connection if you find a virus during a virus scan.

3 Be happy you made a backup
In extreme cases, you may need to reformat your hard drive, destroying all the data on it. Then you'll have to reinstall your software and data, assuming you have the original software disks and clean backups of your files. In this case, you should install your virus protection software on the empty hard drive so you can verify that your backup files and original software are virus-free.

4. Warn your friends
Contact all the people you've recently exchanged information with via floppy disks, email attachments, Zip disks, or CD-R disks, and let them know that your system's been infected and theirs may be infected as well. Tell them what symptoms to look for or the name of the virus.

5.*Do not spread rumors about viruses and beware of virus hoaxes* Everyone has received an email warning from a friend about a new and terrible virus making the rounds. Often these are hoaxes and contain bad advice that will damage – or even infect -- your computer. Beware of warnings that claim a virus is undetectable. In general, if you keep your antivirus software up-to-date, your system will nab the latest viruses. If the e-mail message's subject line includes words such as "Urgent," "Warning," or even "Virus Alert," it's often a good indication that you're dealing with a hoax. Look out for pseudo-technical discussions on the dangers of the virus. Some hoax messages include pure gobbledygook. To create an aura of credibility, a hoax often quotes a well-known company or agency, such as Microsoft, the Federal Communications Commission, or an antivirus company. Check the Web sites of the sources quoted or see your antivirus vendor's site). Remember also that Microsoft never posts virus alerts via e-mail. Beware of messages that insist you delete a file manually. True, at times you should do so, but in the context of the other tip-offs, this instruction should raise a red flag. False alerts always urge you to tell everyone you know. Genuine alerts never do.

The system integrates globally networked computing resources, and creates a dynamic customer-driven library’s set of materials. It allows patrons to select the information suited to their interest and needs and create their own personal pages, which enable quick and easy reference.  The Bibliographic Databases, Electronic Journals and Reference Shelf sections provide the means for the user to have displayed only the scholarly information resources important to their work.  Make your customized ‘My Library’ page, for quick and easy reference suited to your needs. Use the ‘Bookmarklet’ program to add links to the ‘My library’ page as you surf the web. B. Subramanian



Innovations in Online Journal Publishing 
There are ever changing developments in online journals that have leapt forward in the last year or so, arousing interests across a large and diverse group of users, publishers and producers. It is tempting to think that this progress represents a significant step in the shift towards a new form of communication that is evolving from the long-established journal format.   The likelihood is that we have barely glimpsed the true form of the journal of the future.

The Haworth Press Publishing Group has enhanced the value of their publications by providing a powerful format for their electronic journals.  They have designed a one-stop link all of there publications to one URL:  http://haworthpress.com/store/E-Text/ViewLibraryEText.asp. With  one click you can view all the titles publishers by Haworth press.  Here is a one-stop source for cutting-edge for research and information. Until now, there has  been no other publisher that has dedicated time and effort in this area,  Kudos to Haworth Press for this inventive process   C. Perkins



Cash Photocopier

The library is pleased to announce the availability of a coin/bill operated photocopying machine. Copies are 25c per page. The machine is located in Room 113 (Photocopy Room) on the main floor of the library. It will accept bills, nickels, quarters and dollar coins up to $10.00. The machine will not make copies if it cannot dispense change. The bill will be returned to the user. Please note that the machine is not a change machine and before change is issued at least ONE copy must be made.

This is yet another effort on the library’s part to accommodate the diverse needs of users. M.Hussain
