dont worry so much...haha....this is an easy matter..mostly hp which will infected by virus is Symbian based.....and if your pc have virus, and u plug into ur hp, u wont be infected by the virus too...dont worry..the virus, yes, will go into your hp's memory card, but no harm at all...it cant work on your hp because different operating system..but if u plug ur memory into another pc, the pc will be infected...haha... anyway, hp are very less likely to be infected and affected by virus...unless u are using Symbian based hp...
