Every time when I plugin USB drive, pops and says virus detected, I did clean with online tool from trendmicro.com, again after few days if I insert USB drive, samething?. Isn't virus get clean with tool?. after I did clean with tool, if I do again, can't find any, but appears back after few days, why?

The virus might be in your OS and installs itself onto media once it's connected. Have you done a full scan on your system?

I did scan OS manytimes, no issues at all, very clean, only it comesup when I plugin USB.

Open up on linux and delete the virus.
