Solved Partition Data(E:) suddenly appeared

[cobace742]

I had to repair my laptop screen lately and i've left it with a guy for 2 or 3 days. Since then i'm a little paranoid, he asked me for my password and i gave it to him.

First weird thing i noticed, is that a data partition (100Mo) suddenly appeared :

What do you think ?
I'm also interested in an in-depth scan if you would please assist me.

Thank you.

Hello,
A new installation of Windows 7 usually places a 100 mb partition on the main drive. It is a system reserved partition and it is normal. I usually hide it by removing the drive letter using the OS Disk Management utility, since it seems best not to mess with its content. Here's a related link.

If you want to be on the safe side & put your mind at ease, it wouldn't hurt to run a scan with TDSSkiller. It's a quick scan & will tell you if you have any rootkits.

Thank you for your replies. TDSSkiller didn't find anything.

But i also noticed that my CPU is very often used at 100% even though i'm just using Chrome and Spotify.

If you would like to go in depth exploring what is causing this, there is a free program called Process Explorer by Sysinternals. It will show what is running, how much CPU usage a program is using & give you the option to do a web search on any item. (R click on item, at the bottom of the list "search online."

Have you run a scan with a malware scanner such as Malwarebytes or AdwCleaner? Malwarebytes free will work fine, just be sure to uncheck "start free pro trial" at the end of the installation & do a full system scan.

I've already used Process Explorer to see if anything was abnormal, but everything was fine, chrome wasn't using more than 20% tops, and the rest was about ~75% and used by System Idle Process (is it normal ?).

Nothing detected by Malwarebytes Anti-Mawlare nor AdwCleaner.

Maybe you can guide me for one last test with Combo ?

Thank you very much.

If nothing was detected, then it looks good. 75% is good. It wouldn't be a good idea to mess with Combofix since it's easy to hose your system & is more of a heavy duty tool for badly compromised systems. I have little experience with it, so the way things look, I would recommend against it.

Jacee has experience with it, as do other people, so if you want, you can ask them if they think you need to run it.

This is a 'specialized/heavy duty tool' and it can render your computer as a doorstop if not used without trained supervision.

Please don't download and run it unless you are asked to do so by a "certified" malware instuctor who has gone through the use and special training of this Application.

You have been warned. :warn:

Ok, thanks for your help.

Glad you got it sorted . Keep an eye on your system & be sure to run your scanners on a regular basis. Remember, no program gets everything 100%, so use both scanners as well as your AV to run system scans

Something you may want to consider doing is making a system image. If disaster strikes, you can easily restore to the time you made the system image. Keep the image on an external drive if possible.
