Cheers, will see what I can find out, phpinfo shows 512M so that is ok, the filer permissions are fine (its a windows apache server) just tried a quick scan and got
The Quick Scan was unable to finish because of a shortage of memory or a problem accessing a file. Please try using the Complete Scan, it is slower but it will handle these errors better and continue scanning the rest of the files.
error log shows nothing
Will let you know if I find the answer
Many thanks for your help
