Bug fixer

Perhaps try putting "Fixer" on the same line as "Bug"? Make sure to align all elements down the middle. I would try several layouts (like have the text on the right with the symbol on the left). The typeface also looks a bit too bulky, maybe try other font families.

I think you need to push more of the tool aspect of the logo. You have a nice wrench look to the bugs face, try to find more tool elements to work into the body in the same way (more of a hint of the tool, than an actual tool- if that makes sense).

Not a fan of the font, or the way it's laid out- I agree with above comment of making it all one line. If this product is to fix computer "bugs" then your font needs to reflect a more tech style, as well as compliment your symbol. What you have here is more of a novelty, or cartoon, type font.

not a bad idea, the text looks off centered with your symbol, i'm also not a fan of how you've stacked your lettering
