Contacts Have Disappeared

[obieag]

When i woke up this morning, all of the contacts from my "Exchange ActiveSync" were removed and were replaced with 5 random contacts with names like "House", "Sissy", "Big Momma".

I do not remember doing anything different with my phone last night - updates and whatnot.

Should i be worried about a virus? I should be able to sync my phone with my computer at work to retreive all of the contacts, but i don't want to take a chance on damaging my computer (if thats even possible).

Also, it has not affected all of the contacts saved directly to my phone or my facebook contacts.

Thanks,
