If you chat at www.webcamnow.com it's essential to make sure your main hard drive is not accessible (or make sure you don't offend anybody!). I lost 13 gigabytes of data while chatting at the site. You might be also be interested to know that they can take snaps with your webcam without your knowledge. These pictures will be stored in C:\Documents and Settings\****\Local Settings\Application Data (if I remember correctly). If you want to see these you will firstly have to click - tools, folder options, view then tick display the contents of system folders, choose show hidden files and folders and untick hide protected operating system files. You should assume that webcamnow has access to all your data and can do anything it wants with your hard drive. I believe firewalls and antivirus programs are no impediment (zone alarm pro might decrease your vulnerability). I should mention that for the above to be relevant you may have to install webcamnow software (ie they probably wouldn't be able to operate your camera unless you had set it up for broadcasting. Don't think it's only webcamnow you have to worry about, whenever you are connected to a web site there is potential for your data being accessed, manipulated or deleted. The only safe way to compute is to never go online with your main hard drive.
