Windows 7: Virus/Hijacking removal?

As I was looking for more programs such as CCleaner, I downloaded one that inadvertently came with a virus, one that sets up my search engine to Blekko no matter how many times I remove it from the loadup and searchengine. I removed that by system restore, which im pretty sure its still out there.



The second one is, anytime I go to google.com, it goes into a black screen with white letters on top saying "Welcome to Nginx" can someone tell me a step by step way to remove this?


EDIT: The hijacking google "Welcome to Nginx!" went away after I ran CCleaner again, but i'm still a bit cautious about blekko as everyone says, doing a system restore rarely "removes" a virus.

Hi,

I do not think this is a virus. Nginx is an open-source browser used by many sites. Which internet browser do you usually use? Find the option to delete your browser history and the message will dissapear.

The search redirection is a different matter. Please perform an online scan using ESET, and then post back the findings here.

I think it was a virus, as I was unable to access some websites, such as Youtube.com it says Unable to find Youtube.com, even Support.Mozilla.com wasnt working, (Mainly used Google chrome, but decided to see if Firefox was infected as well which it was) This was fixed by the system restore.

Currently still running ESET, its been at 99% for 7 minutes, still scanning.

EDIT: ESET still at 99%, 50 minutes into the scan it found 3 threats so far:
probably a variant of Win32/Adware.iBryte.Bapplication
a variant of Win32/Toolbar.Widgi application
a variant of Win32/OpenInstall application

Ill re-edit once the scan is completed.

Second EDIT: Scan completed, those were the only 3 threats. I checked to quarantine and finish.

What was the name of the program you D/L ed? Please let as know as this will help find a removal program.

MzRamBooster, it came with that program, and the virus/hijacker.

Generally, programs that promise to speed up your PC...don't. If they do speed it up, the amount they do is negligible. In some cases they can render your system inoperable.

A system restore may have worked, however it's suggested that you restore to a second or third point back as some viruses embed themselves in the 1st restore point.

Start by running Malwarebytes and see what it finds. Make sure to check the boxes next to anything it finds and quarantine it.

If you still have problems, the following programs are suggested:

Microsoft Safety Scanner - Antivirus | Remove Spyware, Malware, Viruses Free

What is Windows Defender Offline?

Yeah, I was aware that programs can't really speed up your PC, but I was hoping to find a program to do something similar to what CCleaner does, which is to free up un-needed ram usage so there would be more Free/Available ram etc.

Will check those scanners out, thanks.
