Win32:Dropper-gen [Drp] and Win32:Malware-gen infection!

Viruses and worms
1

Hello,

Every few minutes avast tells me it has blocked two files: Win32:Dropper-gen [Drp] and Win32:Malware-gen
Before that it was Win32:ZAccess-PB [Trj] and Win32:Trojan-gen, but those have stopped popping up.

I followed the instructions on http://forum.avast.com/index.php?topic=53253.0

And so I’ve attached the files, but OTL never made an extras file? Please let me know if I’ve done this incorrectly!

Your help is hugely appreciated.

Thanks in advance,

Kev.
