I beg to differ. You do not need a resident program like MC Shield. All 4 of my USB sticks are immunized and I have stuck them in hundreds of infected pc’s and never an issue. Disabling autoruns is a primary step in staying malware free. Just Google it.

No need to explain myself. Immunize explanation is on the Bitdefender link. Please read the links I posted before commenting. The disable autoruns is for 7 and Vista. Here is XP.

FYI…I have a masters in computer science and work as a systems engineer. I also run a home business repairing pc’s. I make house calls a lot to remove malware. So do not doubt mt knowledge.
