Had something similar happen to my comp at the beginning of the year or end of last? Anyways, had a friend at work take it and plugged it up to his like an external hard drive and ran AVG over the files and then he used some canadian program the only one he could find to rebuild the part of the boot up portion that the virus had taken. He was able to get it to boot up and I backed up my pics/videos and then searched other choices which hp offered a disk for 20 bux had this not worked. Instead after i got it up i did AVG it found a couple more things. I also use malwarebytes along with it that Zillabik suggested one time which also found stuff none else did. Currently still in the same state with some files missing, but virus free. Fighting the upgrade to windows7 due to xp.
