<h1 class="subject">I have tried 3-4 "zip" software programs but am unable to "unzip" zips in email, any comments?</h1>

I'm running Windows XP with 3GHz processor and 512 MB of RAM. I also have AVG free anti virus software and Spyware Doctor.

The best software I have found which deals with ziped files is winrar and its free

Which ones have you tried?

How about Tugzip?
