Help I think i'm infected and not sure what to do now

[robertthurman]

First I want to say Thank you in advance to everyone helping me with this question and even those who have taken the time just to read this post.

The problem I am having is I accidently downloaded a virus meaning I was running Norton and the real time scanner was slowing down the system so I disabled it (DOH!) forgot to turn it back on and I think a virus snuck in through one of my installations, anyhow I have swept the whole system with norton, uninstalled swept with AVG free, unistalled swept with superANTIspyware, swept with MalWareBytes Uninstalled, Swept with Eset trial version Unistalled. No pesky ads on webbrowser but IE still loads pages slow though internet connection is good boot time is tremendously slow considering too that it used to take around five seconds max.

 

I am using a Toshiba All-In-One with windows 8(not 8.1) and a preinstalled factory system with no system disks but a partition with a image for reinstallation, I know how to do this and I have already backed up all my files, call me a Homer but I had a feeling boot time speeds might be due to a virus implanted on the cmos,bios or mbr so I downloaded AVast AswMBR which is scanning right at this moment and MbrCheck from geekstogo which found a non standard or infected MBR or unknown MBR code, I would type Yes to repair but I heard online that doing so can wipe your data and stop you from being able to use the system recovery tool on your computer plus I am not sure wheither this is actually a infected MBR or Unknown.

 

I still have'nt even looked into fixing the cmos or bios, though I did hear the bios chips from mid 90s up are non infectable though I need a bit more evidence to believe call me a skeptic.

Anyway I really hope you can help, and if not thanks for taking time to read this, I do appreciate it.

Cheers.

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll be working with you.
 
     
    
Before we start please read and note the following:

• Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
• Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
• Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
• Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
• Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
• Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
• Note that we may live in totally different time zones, what may cause some delays between answers.
• Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
• If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

I can't foresee everything, so if anything unexpected happens, please stop and inform me!
There are no silly questions. Never be afraid to ask if in doubt!
