Actually, it is MALICIOUS. Suggest removing it Immediately.
Apparently, I found it Installed with a Download of a Video Compression Utility that I downloaded (AnyVideo - I believe) a few weeks ago.
I started looking when I saw that FireFox was running at about 250M instead of the normal 130M Task RAM - (dropped to 130M again after removal). It was also executing ConHost.exe every second or 2 repeatedly - apparently it spies on You and your Pc / Internet etc.
No Program should be doing this. Don't know why anybody would advise anything else.
(I have done past AntiVirus work.)
Simple Removal :
1) Kill ByteFence.exe in TaskManager.
2) Delete ALL files (that you can) in the C:\Program Files\ByteFence\ directory.
3) Rename remaining few files with .dead on ending (file.dead , etc).
4) Restart Computer.
5) Delete C:\Program Files\ByteFence\ directory now.
I agree completely. Yesterday, I was prompted to update the "freemake Video Converter". My AV app quarantined several files; nevertheless, ByteFence was installed and added a service. I found that several other folks had run into the same file quarantining issue and resolved it by downloading freemake directly from its website. This time the AV app had no complaints but the Trojan had already infected the system. The CPU and Disk IO (internal drive) usage kept spiking to 100%, which virtually never happens, and the PC became
very slow. It also consumed a good chunk of memory but since I have 16GB of RAM, it had little affect on performance .
I tried to uninstall it but three processes continued to run: ByteFence.exe and two others whose names began with "rtop." After they were killed the PC's performance immediately returned to normal and I was able to delete the ByteFence folder.
