Thank you to all members who have tried to help me in my time of need. My laptop is now fixed and I have my pictures back - YIPPEE
After posting on the forum this morning I contacted Computer SOS after seeing their ad at the top of the page. Brian and Sheryl kindly replied back promptly and said that my computer would need to be re-installed to fix the problem. Because the laptop has all of my husbands work programs on it I did not want to go to such drastic action if at all possible so I took Mike's recommendation and contacted Dom at Paphos PC Repair. Dom came out to my home this afternoon and has managed to remove the virus' and has recovered all but the last 3 days of my files. Apparently, the virus had not encrypted a hidden area within Windows which held a copy of my files so he was able to get 99% of my files back - Thank the Lord.
FYI: The virus I had was called Crypto-locker and is apparently quite common. Dom said that if people get this virus they should turn off the computer as quickly as possible and call someone out as the longer the virus runs on the computer the more chance there is of not been able to recover anything. He said I had been very lucky. Maybe I should put the lottery on this week

Off to the shop now to purchase an external hard drive to back up my files.
Thank you again to all who have tried to help.
