i wont argue with u on re-flash will solve the problem but please look carefully at his pic...look at the size of the folder & the date...it all the same...now if you said the problem is cause by forced reboot/unmount then why all files are the same size??? unreadable partitions wont have give all files the same size....

need to know this is not a phone virus but a windows virus...as u connect your phone as a mass storage (same as u connect your thumbdrive) it will infect your phone....
now let said that the virus is true...re-flash your phone then when you connect your phone again using the pc that have the virus wont it affect his phone again??? how many time he has to re-flash his phone just to makes this thing go away????

don't tell it a CRAP thing cause this thing you so called CRAP can happen....
atleast i give him a few reason why this thing could happen & a solutions to fixed it not just telling him that what other people said is CRAP JUST LIKE YOU!!!
