Windows 7: Malware issues - Windows 7

Malware issues - Windows 7

I just lent my computer to my brother, and it came back with a "windows 7 security" malware. I don't understand how it got through, but I guess that doesn't fully matter as much as getting rid of this. I ran malware bytes, the free version, and it said it removed the files, but when I restarted my computer, 4 error codes came up:

Windows cannot find 'C:\Windows\System32\igfxtray.exe'. Make sure you typed the name correctly, and then try again.

Windows cannot find 'C:\Windows\System32\kdcmd.exe'. Make sure you typed the name correctly, and then try again.

Windows cannot find 'C:\Windows\System32\igfxtrayTiltWheelMouse.exe'. Make sure you typed the name correctly, and then try again.

Windows cannot find 'C:\Windows\System32\igfxpers.exe'. Make sure you typed the name correctly, and then try again.

Now, when I tried to close these, it re-boots the malware. If it matters, the file doesn't appear to be "real" in the sense that my computer works mostly fine without it, and the icon is a red circle with an X in it.
The only other thing I noticed was, I tried to load up a program that accesses locally stored data (HoldemManager fwiw) and I am unable to load it up, getting the message:
"The following error occurred when trying to open the database: Unable to read data from transport connection: An existing connection was forcibly closed by the remote host."

Please help, you're my only hope! (Starwars reference)

Welcome to SevenForums!

Do you have a restore point from before you let your brother have the computer? See if you can go back to it and then perform another full scan with Malwarebytes.

Which antivirus software do you have running? What exactly did you find during the scan?

Most importantly: find out what it is your brother did with the machine. He was obviously careless with it - humans are still the main reason systems get infected.

Hello Jeas and welcome to Seven Forums.

First, my usual disclaimer: I'm not an expert at anything!

Never, ever lend your computer to your brother again!

I'd suggest making a copy of the free Microsoft Standalone System Sweeper. Run the full scan and see if that doesn't help.

You could also try the free Hitman Pro as yet another malware scanner.

Hitman Pro 3 - SurfRight

igfxtray is a process which allows you to access the Intel 81x series Graphics configuration and diagnostic application for the Intel graphics chipset. This program is a non-essential system process, and is installed for ease of use via the desktop tray. You could uninstall them if you want to. Since I'm not an expert at anything I'm not sure if you can download clean copies from the Intel website.

And not to sound like I'm preaching, but this is a good example of why a system image is so important. If a machine gets corrupted by malware or anything else, a system image can get the machine up and running to a known clean condition in minutes.

I was actually making a point of not saying it so bluntly - but, yeah. LOL.

The above it the log from the scan. I'm about to try the other malware removal programs posted in this thread.

He won't tell me or admit it was him that got the malware, so I'm not 100% sure, but I agree with you guys that I'm never lending it to him again.
