a. Always keep your network shares password protected and read only unless really necessary. b. If using Windows 9x then ensure that you have updated your copy of Windows from http://windowsupdate.microfost.com because some vulnerabilities in Windows 9x allows the remote attackers (or in this case viruses) to unlock your password protected shares (it takes approx. 10 seconds max. for a vulnerable share to be cracked). To check whether your shares are vulnerable or not you can download xIntruder from www.irctoolz.com and check your system for this vulnerability, explanation on the use of this utility is beyond the scope of this article. c. Always write-protect your Floppy diskettes if you only want to read from them, this will ensure that any viruses on your computer don’t transfer to the floppy diskette without your knowing. d. Visiting Hacking sites or sites which invite you to download Freeware can transfer viruses or Trojan Horses without your knowing. Do not visit such sites unless you are really sure what you are doing. e. And last but not the least install an Antivirus, after using all types of Antivirus software my choice is Trend Micros PC-Cillin, it is the best antivirus I have ever seen, Second priority is Norton Antivirus, McAfee goes at the last of the list. But this will cost you, if you are interested in a free antivirus then you should get AVG Antivirus from www.grisoft.com. I have never been interested in installing an Antivirus because it makes a notable decrease in your computers performance, I for my self prefer going to http://housecall.antivirus.com and giving my PC an online scan for free, but for you people it is not recommended there is no exchange to installing an affordable Antivirus specially PC-Cillin. f.

There is no real way to protect yourself from cracking but one can satisfy oneself by taking certain measures, some of which are as follows: a. Install good firewall software, if you are using PC-Cillin 2003 it comes with an excellent firewall option performing equally to specialized firewall software. This will stop crackers from attacking your PC. b. Disable protocols which you wont be using for network connectivity e.g. NetBIOS if you are not a LAN, IPX/SPX if you are not on a Novel network etc. these protocols makes your network connections more vulnerable to cracking c. Keep Remote Connection Services Disabled d. Keep Remote Registry Services Disabled e. Disable Guest and Administrator accounts for remote login f. Use other user names to login to your NC g. Ensure that you have installed the latest driver for your Network Interface (e.g. Modem, LAN Card etc.) h.
