I have 3 files that norton does not consider a threat but I cannot delete them. They are in C/Documents and Settings/User/Local Settings/ Temp/Temporary Internet Files/Content.IE5/G54XYV4X.... The name of the files are too long but one starts with click,... another starts with activity,... and a third starts with betr=mvfne.... I tried to delete them in Safe Mode but could not. I am pretty sure these are spyware but are they anything more than annoying? Can I get rid of them? Should I get rid of them?
