Update your Anti Virus Software! And then run a scan
You can also try downloading
http://www.download.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html
Which scans your computer for viruses and will not clash with your anti virus system, once installed make sure you update it and then run a full scan.
If you don't have an Anti Virus program well.. seriously.. tut tut to you, try getting a free one like Avast or AVG.. but paid for ones are usually better and have more security features.
Also!! i have found that it says if you can Kill the process as soon as possible go into task manager and end it!
