If you wanna go that route I would first update your antivirus. If you wanna Run scans, good tools you can use are:
1)Malwarebytes
2)TDS Killer
3)RRKiller (use first before anti-virus
4)SuperAntiSypware
5)Combofix (This is a really strong tool and could damage your PC, but is thorough)
*Note that these may not catch it though if you do have it
