Hi guys, how are you all? Fine I hope.
Well, I have a big problem. I just put in my uncle's pen drive in my PC and it proved to be a major mistake. The pen drive contained the Sality.y virus and it quickly infected my PC. I had Avira and although it detected the infection, it was unable to prevent it from spreading. I scanned all my PC and deleted/quarantined infected .exe files. Naturally, when I restarted my PC, I couldn't launch Avira again. I tried to install CCleaner, Norton AV, ClamWin AV, but to no avail. The virus infects .exe files and hence I can't launch any applications now.

Can you please tell me what I should do? Anyways, what is the procedure to get rid of a virus that makes installation/running of a AV software impossible?

Thanks a lot for reading guys, please help me!

Abhi.

NB : I am attaching the hijackthis log here.

Hello, Lophatphuud!

thanks for the reply!

I tried that first solution! With Malwarebytes-Antimalware, I performed quick scan. But it couldn't find any infected file. Here is the log!

Then I thought may be I should go with full scan! But then also, Malwarebytes couldn't find any infected files. Here is the log of that scan!
