I keep getting a popup that says: avast! Warning A Trojan Horse Was Found!?

File name: C:\DOCUME~1\Owner\LOCALS~1\Temp\ac8zt2\m... (whatever that means)

Malware name: Win32:Agent-LTS [Trj]

ect..... Then there are options to click on:

"Move/Rename" "Delete" "Move to chest" (it says Recommended action: Move to chest) %26 then another option: "No action"

Apparently avast! charges $39.95 for their clean-up program. I know there are free clean-up programs out there, but I don't know which ones are ok %26 which ones might make things worse (or just not work). My computer is fairly old too (like maybe 5+ yrs-I don't know, got it used).

Anyway, any help would be appreciated. Thank you
