Check your antivirus

 you can test your anti virus is it working or not. Just follow my instruction:

# open a wordpad or note pad and save this.

X50!P%@AP[4\PZX54(P^)7CC)7}EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

save it as eicar.com . while doing this your anti-virus should stop you. its not harmful either but if the anti virus is active it will warn you. if it does not then your anti virus is good for nothing .
