Malware messed USB ports

few days ago i got infected by rogue malware.. i remove it (or i think i did), but my usb internet dont work no more... last 4 days i try everything, but cant find problem....

here what is about: when i plug internet usb stick it show it in "my computer as drive "F" on few seconds... then disapear and show as drive "G", and create unexisting virtual drive "F" (however i cant open drive "G" even it show stick is in it")(same appenr in all ports)... however.. any other usb stick work fine... so i thought it is problem in my internet usb stick, not in port... when i try on other comp, internet usb stick work normal... seems like usb stick work fine, and ports work fine, but just dont work together..

one more thing... in "disk management" mysteriously appear unexisting drive with no letter... when i click right click on it, all options are grey, only "delete volume" is possible to click... when i try that it say "the request could not be performed because of an I/O device error"... dont know is it connected with my usb ports problem tho... any help plz...

 

i found what problem is with my "no letter" drive.. and it seems its much worst then i though

this is what PartitionMagic software say about my problem:

#110 Partition table number of sectors is inconsistent
The hard-disk partition table contains two inconsistent descriptions of the number of sectors on the hard disk. This error is serious if both DOS and another operating system use the hard disk. Because DOS uses one description and other operating systems may use the other, data loss is likely once the partition is almost full. To resolve this problem, see the instructions in Resolving partition table errors.

#117 Partition's drive letter cannot be identified
Under OS/2, PartitionMagic must be able to find the drive letter for each partition before modifications can be made. There are various reasons why OS/2 might not be able to find a drive letter for each partition. For example, a driver on your system may change the drive letters from their defaults, or your partitions may not have serial numbers.

i was totally unprotected when malware attacked.. it was "system check" first day, and "internet security" second day, immediately after i was remove first one... coudnt believe it can make such damage any advice?
