BROTHER SAY PHALI BAAT K AAP JUB BHI KOIE VEDIO DOWNLOAD KAREEY ISS BAAT KA KHAZZ KHAYAL RAHKEY K JISS SITE SAY AAP DOWNLOAD KAR RAHEY HAI WOH SITE TEEK HAI TRUSTED HAI PHIR DOWNLOAD KAREEY JASSEY YOUTUBE ETC ETC SITES HAIN..
2ND AAP APNEY SYSTEM KO FULL SCAN KAREY YEH VIRUS KI WAJA SAY BHI HO SAKTA HAI KYUN K JO EXTENSION AAP BATA RAHEY HAAI UNDF

UNDF is an undefined file. This may be because it is corrupted, or it is still in the process of being downloaded, and therefore vital information is missing. It is not a file type.
SO HO SAKTA HAI K DOWNLOAD COMPLETE HI NAHI HOTI YAH FILE CORRUPT HO JATI HAI VIRUS KI WAJA SAY....
MAZEED REHNUMAIE K LEY CHECK KAREE
