You can download & install MalwareBytes' AntiMalware on your system from http://www.filehippo.com/download_malwarebytes_anti_malware/ it's listed as Shareware but the same installer will install the freeware version as well.
During installation leave all defaults in place so that updates are downloaded before the first launch of the program.
Perform a Full System Scan & fix any errors found. When your done you may post the logfile here; let us know if you need help posting the logfile.
