First of all sorry for my english bcz it's not my main language and it's 1AM. So yesterday i installed or at least tried to install a torrent of The Spongebob movie: Sponge out of water. As soon as i started the installer i noticed it wasnt installing the movie but other malicious programs so i cancelled it, immediately scanned with windows defender and malware-antibytes, later i also scanned with mbar with no succes at all. I searched online for a while and they said to try gmer, but again found nothing which is weird bcz i keep finding these folders and files with rlly long names and random numbers. It infected some folders like steam and makes copies of existing folders like skype but instead of skype maps and folders it contains maps and folders with these random numbers. I tried deleting every suspicious folder by manually going through every single map in C:. Yet i still think my pc is infected bcz it is going rlly slow and it crashes alot with errors that never occurred before.

 

Again sorry for my english and i hope someone can help me as soon as possible bcz i feel like its getting worse over time.

Do not remove the catroot folder. It's an operating system folder managed by Windows.
Unless you have an error listing the catroot2 folder I would not do anything.

You can refer to this article but I would NOT do anything at the moment.

Open notepad (Start =>All Programs => Accessories => Notepad). Please copy the entire contents of the code box below.


start

CreateRestorePoint:
EmptyTemp:
CloseProcesses:

HKLM-x32\...\Run: [] => [X]
Handler: WSAMVCUchrome - {086BD280-4613-43B5 -  Geen bestand

S3 dcdbas; \SystemRoot\System32\drivers\dcdbas64.sys [X]
S3 IntcAzAudAddService; \SystemRoot\system32\drivers\RTKVHD64.sys [X]

End
Save the files as fixlist.txt in the same folder where the Farbar tool is running from.
The location is listed in the 3rd line of the Farbar log you have submitted.

Run FRST and click Fix only once and wait.

Restart the computer normally to reset the registry.

The tool will create a log (Fixlog.txt) please post it to your reply.

There is nothing to worry about the proxy item found by the AdwCleaner tool.

Clean it if you want.
