Minecraft Username: _Malicious

Problem: I got on my computer today to get onto the Dalek mod server, only to find the new minecraft launcher had installed. I click on the slide down button but when it was loading up, I got an error.
Evidence/Screenshots: Unable to save download. client-1.7.xml

Name: client-1.7.xml

URL: https://launchermeta.mojang.com/mc/log_configs/client-1.7.xml/6605d632a2399010c0085d3e4da58974d62ccdfe/client-1.7.xml

Error details: Attempting to move successful download to C:/Users\user\AppData\Roaming\.minecraft\assets\log_configs\client-1.7.xml

The process cannot access the file because it is being used by another process

The last bit is confusing, because I had nothing else open.

Fixed, just had to reinstall the forge file in case anyone had the same problem.

--EDIT--

I have also found that uninstalling ByteFence, an anti-malware program will stop the issues of downloading versions of minecraft.
