my mcafee antivirus is picking up a potentially unwanted program called prcviewer. Web searches give a lot of sites that talk about prcviewer but some of them look like sites that can potentially cause me to accidentally download a virus. I'm writing to Microsoft for answere regarding this unwanted program.2 people need an answerI do too

I have the same problem - it also refers to a file in a subdirectory called jnana

Update your Anti-Virus and run full system scan and if you still having problem contact support.
