Hello, In fact, when a PC is infected the most thing that drives me mad is when the antivirus doesn't find anything suspicious. Well, I have trying to launch Malwarebytes dozens of times but in vain, it just flashes then disappears, same thing with hijackthis... I can't make any security program load except kaspersky which is loading from boot. Besides, any webpage I open, as soon as the virus or whatever is sees the word malwarebytes, it shuts the browser immediately, so when I surf I make sure I misspell the word to keep browsing Avira can't open too... Same issues with safe mode. Thank you for suggesting any trick.
