From memory, WINZIP is still free to use from winzip.com
Be sure to select the right forum for support since this forum isn't about that utility. There are other unzippers out there, but what I see is that you need to use GOOGLE.COM so you can be more self-supporting.
Thankyou I took your advice and used the adaware program and have now removed 300 and more pest files. However I have tried to download the starter program which will enable me tocontrol the start up programs, it says that this is in compressed format I tried saving it uncompressed and it did so ( I dont have a programme for compressed files- or so I believe)- i have no idea where it has gone and how to get it started!
