Suspicious Files Detected

The problem is, I have no file to upload.

Download and run TDSSKiller following instructions here.
After you finish scan, there should be report file on location similar to C:\TDSSKiller_*.txt.

Attach it to your message.

Hi, there didn’t seem to be any link to instructions, however I have downloaded the software and run a scan. please let me know if there were any special instructions that I may have missed.
The text file is attached as instructed.

Something else new. When I completed my most recent Avast Scan, I deleted the “virus” files it found same as I’ve been doing each time. To date it’s just given a green tick with no information and gone on the next step in the Resolving Issues process.
This time I closed the scan window after Step 1 of Resolving Issues (ie resolving virus issues) When opened the scan again it said, “Resolved Issues: NaN”.
Not sure if NaN is the name of an infection? I’ve attached a screen shot.

It was my mistake because I forgot to paste link. Sorry.
TDSSKiller didn’t find anything so I can say for sure it Avast report. NaN is acronym for “Not a Number” and it is Avast error. Can you try to reinstall Avast?

Hi, now that you explained the meaning of NaN, I don’t think Avast is doing anything wrong. Rather it was a reflection of the fact that I was trying to delete files that it had already deleted (due to closing and reopening the process)

I’ve disconnected my PC from the internet as I’m nervous about what’s going on. I’m using a tablet to post this update! Avast is still finding the same temp files, only now the number seem to have reduced to 35.

I also ran a Rootkit scan from Spybot Search and Destroy. It found a number of processes etc and I understand these may not necessarily be malware. To my untrained eye, there is one item that seems a bit odd.

File: “Invisible to Win32”, “C:\Boott! s”

I cannot see that file if I browse to C:
I will attach the complete report.
