USB Virus/Worm in both Windows 7 and Linux?

Hi,

Because of a USB virus/worm that infected my computer, I recently DBAN-ed and formatted my hard drive then used my Gateway recovery dvd's to reinstall the Windows 7 os.  My os was still acting "funny" and I did a slew of virus scans, but only one so far (Norman Malware Cleaner) detected a couple of malicious files and deleted them.

The kicker is that this virus(es) also ran when I booted to Ubuntu linux and messes stuff up. I tried to run a number of scanners and cleaners, but most of them refused to run and the scans that ran reported no problems. The only one that started going and reported malicious files was Sophos savscan.   Savscan identified some suspicious files until the savscan failed and wouldn't restart.  (So, whoever is perpetuating the myth that linux doesn't get viruses needs to open their eyes)

Here is what Savscan identified as suspicious in linux before it stalled:

/lib/modules/2.6.38-11-generic/build/source
/lib/modules/2.6.38-8-generic/build/source
/lib/firmware/vxge/X3fw-pxe.ncfl  Password Protected

T1:X3_101115_1_8_1_expROM_FW_uni_template_eeprom0.bin
/proc/sysrg-trigger

Did this malware corrupt the BIOS?

Thanks much!

P.S.  What do I do now?
