Hello sonll and welcome to MalwareBytes forums.

Firstly, be advised that you gotta have at least a minimum of computer-savvy to do some basic computer tasks.

If you are not comfortable, and there is no shame in that, you should consider taking the system to a local reputable small computer shop {but just not a Bigbox store}.

Do you have a backup of the system from before the infection(s) started ? If so, tell me what & from when.

Yes, a factory restore will generally overcome the infection, but doing that would cause the loss of all programs and data & user files that were added after the computer came new from the facory.

Backdoor trojan warning:ZeroAccess / Sirefef

This system has some serious backdoor trojans. ZeroAccess / Sirefef

This is a point where you need to decide about whether to make a clean start.

According to the information provided in logs, one or more of the identified infections is a backdoor trojan. This allows hackers to remotely control your computer, steal critical system information, and download and execute files.

You are strongly advised to do the following immediately.

1. Contact your banks, credit card companies, financial institutions and inform them that you may be a victim of identity theft and ask them to put a watch on your accounts or change all your account numbers.

2. From a clean computer, change ALL your online passwords -- for email, for banks, financial accounts, PayPal, eBay, online companies, any online forums or groups.

3. Do NOT change passwords or do any transactions while using the infected computer because the attacker will get the new passwords and transaction information.These trojans leave a backdoor open on the system that can allow a hacker total and complete access to your computer. (Remote access trojan) Hackers can operate your computer just as if they were sitting in front of it. Hackers can watch everything you are doing on the computer, play tricks, do screenshots, log passwords, start and stop programs.

* Take any other steps you think appropriate for an attempted identity theft.

You should also understand that once a system has been compromised by a Trojan backdoor, it can never really be trusted again unless you completely reformat the hard drives and reinstall Windows fresh.

While we usually can successfully remove malware like this, we cannot guarantee that it is totally gone, and that your system is completely safe to use for future financial information and/or transactions.
