Yesterday mom got an e-mail from Aunt You that had a strange DOS file and objectionable pictures. I think a virus has affected her computer. Mom opened it without knowing what it was and today the antivirus detected a trojan in her computer with the file avpo.exe.
I don't know if that virus and the e-mail are related, but just in case, here's a site that tells how to remove it. I followed the instructions and so far everything looks fine.
Uncle Jiann, Felix, Aunt Sheau, and Cindy were also recipients of the e-mail. So everyone be careful.
