USB Drive infected by Small - CBL in Recycled/Driveinfo.exe, Not being removed

I use windows XP SP2. System Config are Pentium IV, 256 mb SD RAM, 1.6 GHz Processor. I dowloaded some Zip programs from Softpedia on a cybercafe and saved it to my USB drive 256 mb. When connected to home computer Avast showed it infected by Win32:Small-CBL [Wrm]in Drive Letter X: Recycled/Driveinfo.exe. Despite the suggested action of Move to chest the drive is now not being recognized by the system. Now another partition of my hard drive is infected and when clicked to open it show choose program to open dialog box. Though repeated attempts hae been made to remove it by avast but it does not work. Please Help…

What is happening? Is there any error message?
Or just the virus come back over and over again?

If a virus is replicant (coming and coming again), you should: disable System Restore; clean your temporary files; schedule a boot time scanning with avast and use trojan removers.
