I am in WIndows 10
Last night I got infected with something.
Every so often an ad from an invisible window would start playing, i identified that It always came from a process called 'nine'
If I opened CCleaner, it would automatically close after a few seconds.
What I did was going to the task manager, in the Startup tab and look at all the entries that seemed suspicious(there where a lot), I then tracked them to their location in disk and removed them manually. All of them remain deleted expect for "hallowell", which takes me to a folder called "fearlessness", this folder has an application called harassing inside.
Then, I ran AdwCleaner, it found some malicious software and then I used it to remove them.
After doing both of these thing both the random ads stopped and CCleaner worked again, but now I did not have internet access from any of my browsers(If i did a ping from the command line it would reach its destination). They say that they cant connect to the proxy. I believe this is caused because many of the Startup processes that I removed were called network, and they were in a folder that seemed suspicious.
Also, when I do Window Key + S to search something in my computer it doesnt give any result.
I then tried to change my proxy settings, but it everything is greyed out and it says that the settings can only be changed by the organization.
Then, I ran the Malwarebytes Anti-rootkit tool, it found some threats and removed them using the same tool.
The problem with the proxy and the search function remain.
These are some of the applications that I removed manually that were on auto startup:
