l cannot delete it no matter what l do, l hve found several articles on google but there so complicated!!
Hi, l downloaded the malware program and it seemed to do the trick however as soon as l connected back online l found the virus had resurfaced, l ran the scan again and deleted the offending files but again it resurfaced when l connected!!! any further clues.

Many thanks for help so far
