Hello, not sure if it is malware but DO Not run a Temp file or registry cleaner as it may eliminate them.
Yes post the ESET log.
Lets try this.
There is an infection family that will also hide some/all the files on your computer from being seen. To make your files visible again, please download the following program to your desktop:UnHide
Once the program has been downloaded, double-click on the Unhide.exe icon on your desktop and allow the program to run. This program will remove the +H, or hidden, attribute from all the files on your hard drives. If there are any files that were purposely hidden by you, you will need to hide them again after this tool is run.
