Done as instructed. Many thanks for your help. Here are the logs u requested. However, when i searched for Cthelper.exe and PCsync.exe they were not found so i therefore could not run the scan and provide u with logs for these. This appears to have taken the next step to curing the problem. I await ur advice as to the next... over to you...

Many thanks for your continued assistance.
It is gratefully received and appreciated.
