回复：I had same problem today.

I cleaned the virus (Trojan Vundo virus). I tried to post how you can do it but failed twice. probably because it is too long (lengthy).

你照步骤做做看.

我是菜鸟.以下步骤是我今早在DELL SUPPORT的BLOG (COMMUNITY DISCUSSION)那儿查到的.我忙了大半天,总算把柄TROJAN VUNDO VIRUS CLEANED.

Sorry, I can not post it. I will try to do it as a new post.
