Well here it is!!... My computer done some configurando y limpiando during the restart which looked promising!
Fixlog below fingers crossed all went well...
Michael or Alan1998 - I couldnt agree more!.. Essexboy is the best!
With regards the other little suspicious file... i rescanned with all the programs you recommended and it didnt pop back up... then i searched for the file location and it was no longer there... i presume ive zapped it and it hasnt moved somewhere else (i think im starting to give these viruses a little too much credit - like free thought!)
Thats why i asked why avast hadnt picked it up as i regularly complete full system scans ... bit worrying!
Thank you so much Essexboy feel as though we could possibly be at the last hurdle... Its been emotional
