My question arises from the fact all virtualising programs now admit they can't protect the MBR from rootkits such as TDL&Co.,apart from Diskshot which has not been translated yet. I use three pcs with three different configurations which i'd like to protect,please bear in mind computers 2&3 run GRUB as i dual boot Ubuntu: 1-Windows7:Comodo CIS5+ToolwizTimeFreeze and MBAM,Superantispyware free on demand 2-XP (GRUB): Sandboxie + ToolwizTimeFreeze and Comodo AV,MBAM,Superantispyware on demand 3-netbook Windows7(GRUB): Sandboxie + ToolwizTimeFreeze and Comodo AV,MBAM,Superantispyware on demand. In computer 1 I also do routinely scans with MBAR (Malwarebytes anti rootkit prog) and KasperskyTDDS. What I'm planning is doing the above plus perhaps a new image every now and then ( two weeks?) whether i need it or not, just to reinstate the MBR. (I wonder if you can successfully backup and recover just the MBR with PARAGON ) (I also wonder if the new Comodo V6 with its Kiosk can take care of MBR threats...) Any suggestion/advice on this matter regarding the MBR and/or my setup is more than welcome,thanks.
