PC infected

Hi, for one year I use AVG and Malwarebytes for my PC. I usually have almost no viruses. But for 4 or 5 days, I have the impression that my pc is slow, more than usually. I had AVG9 and there was a pub for AVG11 so i downloaded it, but i had some problems to install it and another problem so I installed Antivir instead today.
After analyzing my computer during 2h30 (but 30% only, i hadn't the time to finish), 3 viruses + 1 keylogger were detected... Moreover, it was markedthat the file "keylogger.exe" was created one year ago, so I'm really afraid that someone i know stole all my passwords and have been spying me all this time... Help me please

3 years ago my brother used a keylogger or spyware on my family's only pc and today, I am suspecting him to try this again (now, we all have our own computers) because there are strange things :
- Some weeks ago, he lent a USB flash drive to my sister and she detected a keylogger. He wasn't surprised at all and didn't say anything.
- 2 weeks ago, he lent his computer to my father for work, I quickly watched the screen and there was no antivirus working and a lot of toolbars. When my brother is using is account, there are 0 toolbar and the antivirus is working.
- When my brother's pc is working, mine becomes slow, even if I am not doing something on Internet. I have no problem when everyone's pc is connected but my brother's.
- Some minor details : he loves doing illegal things, he is a killjoy/manipulator and at home, he spends almost all his time on Internet.

We share the same network so I'm afraid he found a way to infect our computers again :/
The main computer of my family is my father's and he has no password.

 

Ok, thanks, i will wait until my father comes back from work to do the scan on his pc.

Could you also help me to protect my network from my brother in the case where he tries to infect me please? Thanks.

 

For the moment on my computer after 2 hours (47%) there are two threats found :
Win32/Adware.ADON application
une variante de Java/TrojanDownloader.OpenStream.NAU cheval de troie

The scan takes a long time so I don't find the time to scan my father's computer completely... But after 30% there were 5 or 6 threats detected

 

It was 49%, I was playing a game, and 5 min after it was finished.

I deleted the two threats but nothing seems to have happened :confused

 

I found the threats with eSet but I don't know how to find the exact path to the files. SAS and MBAM don't find any viruses (on my pc).
I will try to do the scans on my father's pc but I don't know if my father will let me.
