Hi Pondus,
Yes I do understand that you needed the name that avast gave but I cannot find it anywhere. I did shut down the system (although it took much longer than normal) to try and re-create the problem but thus far, Avast has shown nothing.
I cannot confirm if it was W32:Evo-gen [susp] = suspicious or not. All I know is that Avast wanted to delete the file, it didn't say anything about sending it to the virus chest which is why I told Avast to ignore it when it was highlighted. Do you think perhaps that by taking the 'ignore' action Avast will no longer show it up as an issue?
I'm really am very sorry for my dumbness, people like me must seriously get on your nerves. I am a true newbie at this so please forgive me.
I've also just realised that I've probably put this in the wrong forum too? Ooops!!
Thanks for all your help and advice.
