Hello Vjay -

Very sorry to hear about your problem. I was also infected a little over a week ago and although not qualified to assist you, the fine folks here are you will be in excellent hands.

Good luck.

Hi vjay0204,

Welcome to Vista Forums!

You have two very nasty infections (at least) and a clean installation may be required - but I'm not the expert, so I'll let them make that call. Let's start by finding out exactly what you do have so our security expert can review the results and offer advice on how to proceed.

Here's what someone (the same person who provides the removal instructions that follow) said about this particular infection. It doesn't sound good - but before you take drastic action like re-installing, let's try these options and then get an opinion from our security expert, Jacee. http://www.bleepingcomputer.com/foru...3#entry1977393.

I'm not the security expert, so I'll just offer some advice on a removal process that may at least help with how the computer is functioning (even if it doesn't fully resolve the problem): how do i remove Backdoor:Win32/Cycbot.B. But even if you do this, you still need to do the following as it is no guarantee - no matter what the security scan results reveal (and ultimately did not work the last time it was tried where you originally posted). Plus you may have another one and maybe more which I did not address here.

Download, install, update and run Malwarebytes: Malwarebytes and copy the results and paste them to your next reply.

Download, install and run HijackThis: HijackThis - Trend Micro USA (the full version, not the beta version) and again copy and paste the results to your next reply (and yes, we know it's typically quite long).

This should help our security expert get off to a running start on your problems. In the meantime, I recommend you use a different computer and change all the passwords and logins to every site you've visited where there is information about you - especially banks, financial institutions, your ISP, your e-mail provider, and, if you keep financial information on the computer, your ATM password, passwords to all your credit cards and investment firms and so forth (and possibly changing the account numbers as well depending on what's on that computer). Do not use the infected computer to access any of these places until it is repaired or whatever you use or wherever you go will need to be changed again. The problem is that this virus compromises your system so it can be penetrated and information on it can potentially be accessed and may already have been accessed (despite whatever security you are using).

But first, post those two logs so the experts can get started whenever they arrive.

I hope this helps.

Thanks and good luck!
