System Check is NOT legitimate.

Quote:
System Check is a fake computer analysis and optimization program from the FakeHDD family of rogues. This rogue displays false alerts that are designed to make you think that your computer has hard disk problems that have lead to corrupt and missing data. It displays these alerts in order to scare you into purchasing the program so that you can fix these issues. In reality, though, there is nothing wrong with your hardware or data, so please ignore any error messages that this program displays. System Check is installed through hacked sites that exploit vulnerabilities in software that may be installed on your computer or through fake online scanner pages. Once installed, System Check will display false error messages and security warnings on the infected computer. These messages will state that there is something wrong with your computer's hard drive and then suggests that you download and install a program that can fix the problem. When you click on of these alerts, System Check will automatically be started.
Removal instructions can be found here.

Remove System Check (Uninstall Guide)

Quote:
To make matters worse, recent variants of this family have been know to install the TDSS or ZeroAccess rootkits as well. These rootkits will attempt to stop you from using security programs that may help you to remove this infection. If you are infected with System Check and are unable to update your Malwarebytes's Anti-Malware definitions then you most likely have this rootkit installed.
Suggest you run TDSSKiller to make sure you have not picked up a rootkit.

Hello all and first of all many thanks for helping!!

I don't have an antivirus program An my computer only has one user, so I can't check.
Cottonball, those were the messages I got:

Critical Error
RAM memory usage is critically high. RAM memory failure.

Critical Error
Hard drive clusters are partly damaged. Segment load failure.


I did not know where to start and what program to download first. So I started fallowing your advices from the beginning.
I visited this page Remove System Check (Uninstall Guide) and I read everything.
After that I went to safe mode and downloaded Malwarebytes, because I also read here Remove System Check virus that there is no need to try to remove it manually.
I also downloaded this thing TDSSKiller Download
The last thing I installed was Avast.

And after all of this I ran my computer normally (not in safe mode) and did a scan with both antivirus programs and they both said no infections an viruses were found (that is after a few previous scans and some deleted viruses).
Well I hope that this was all, thak you again for helping I really appreciate it!

Glad it looks good. Now, what you need to do is run a full system scan with Malwarebytes, your AV & run TDSSKiller again. A full system scan will take some time depending on how many files you have, but be sure to do it to weed out anything that might be hiding. And keep a sharp eye on your system for suspicious behavior.

If everything look good after running the scans, you may want to consider making a system image. That way if something serious strikes down the road, you can restore to the point when you made the system image.

Backup Complete Computer - Create an Image Backup

BTW, those error messages are nothing but BS. Programs like that (Scareware) attempt to trick you into buying the software so they can fix non-existent problems.

AlbinoPanda,

Since you ran TDSSKiller, the tool creates a log normally in the C:\ drive where the Operating System resides.
Logs have a name like:
C:\TDSSKiller.2.4.7_31.05.2013_15.31.43_log.txt

Is it possible to attach or post the TDSSKiller log in your reply?

We want to make sure all is well.

Also, please open Malwarebytes Anti-Malware, and obtain its last report by clicking the Logs tab.
Could you provide its log also?
