My anti-virus software keeps going nuts over it And can't seem to delete it, says system can't find the media even though I'm staring at the file.
Found this file while running registry Cleaner, have been having a problem with popups, this is spyware

from what i know its a defuka adware file
F-Prot detects it as "Dyfuca" security risk; F-Prot started reporting it soon after a problem with some advertisments started popping up - so it was not in the system before (else it would be reporeted before)

It has been dropped on my computer with a couple of other spyware programs
installed with free audio recorder, along with loads of spyware. signed by Avenue Media N.V. with invalid signature.
I got it too within a flood of spy etc. ware. Seems like it has to do with an mysterious "c:\uploads" folder which is not visible in the explorer. Found this using Treesize. Antivir detected nem220.dll and optimize as Trojan.

Best practices for resolving nem220 issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active nem220 process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the nem220.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
