CPU usage 100%

Hello! processor amd fx 8320, merely loaded 4 cores from 8 to 100%, as soon as you launch task Manager or process explorer, then once the load drops ( like when off the Internet, too, with no load, not sure).I believe that the reason downloaded yesterday (12.10.2017) game with torrent, the distribution of which was included the miner, which I learned today.
In process explorer I noticed. what svchost.exe starts and immediately turns off errorsheck.exe well I found it and deleted, to no avail... also antivirus periodically produces the message 100% CPU usage file Name: attrib.exe
Full path: c:\windows\system32\attrib.exe
Please help!
Vidyuhi way too loaded in simple 70-75%, after removal errorsheck ceased, and the percent no, sometimes monitors for process explorer is popping up a red errorsheck for a second, I catch him and open the file location, but egechilca there, because I deleted it, there are only files with the file extension .sol
Is Norton, Doc.the web is also checked, all clear.
Shake torrents on one site for 4 years, was unfair releaser, was immediately banned, and bowel on the computer left.
