So a couple of months ago my laptop became infected w/ a sirefef trojan (not really sure which one). I've been using bitdefender for years and have never had a problem like this, but bitdefender can't seem to clean this awful trojan. I initially tried doing some research and have had no luck following "how to" guides I've come across online. Anyway, my laptop got to the point where it was unbearable to use, so I haven't even attempted to use it for the past month or so. It's less than a year old, has Windows 7 w/ 64 bit OS. Luckily I have my trusty macbook as a back-up. I'm determined to get this resolved, even if that means junking the HD and putting in a new one, but I decided to start doing more research again today and came across one of your posts where you helped someone w/ a similar problem. If you could get back to me whenever you get a chance, I'd GREATLY appreciate it! Look forward to hearing from you! Thanks!
