Thanks for the replies.
I think DaveLembke has a valid point. I have SAS and MalwareBytes (free) on my desktop computer as well as MSE to name a few. HJT etc. etc. Oh and yes I found MSE does have that option (thanks Salmon Trout).
I wanted to give the drive a thorough going over.
Im (reasonably) sure I had the drive installed when I tried to virus scan it.
Adding the drive has come about from other issues on this computer. Ultimately I think it was a flat battery in the motherboard. 2 beeps at startup, cannot find SATA 0, slow to load Windows past the blue screen, so on.
So I am going through the system bit by bit and decided to add another drive.
However I suspect the C: drive may actually be ready to fail. (That might be a different posting later)?
Back to the question yes I tried to look around on the Antivirus scan on SAS & MalwareBytes, but Im (reasonably) sure/unsure I had the drive installed when I tried to virus scan it.
I guess I will just have to step back for a minute and start at the beginning to make sure I am doing it all right and fix 1 issue at a time.
