2012 MBA acting strange

This just started happening out of the blue. Typing into the url bar of safari is really slow to respond and when I use the touchpad it constantly selects and hifhlights text or makes a selection box when I 2finger scroll.

No idea what caused this, anything I can do?

Ok I think I've isolated the problem. It seems to be the trackpad.

Whenever I move the cursor around on a web page or anywhere it thinks I am hard clicking so it emulates the behavior of highlighting or trying to mass selection. It is EXTREMELY annoying and makes the touchpad basically unusable because any time I try to do something I end up selecting something I didn't want to select. It doesn't do it 100% of the time but it does start doing it randomly.

I was using my MBA just fine last night and then it just randomly started happening.

What can I do? Does this sound like a hardware problem? I tried resetting the PRAM and SMC but it didn't do anything.

This sounds crazy but I think the problem is some residue on my trackpad/fingers. Right now my fingers are moving across it smoothly and I don't experience the problem but earlier the trackpad felt "strange" and my fingers were sticking on it. I washed my hands like crazy and cleaned the trackpad and it was still doing it so I didn't think that was it, but right now it's not doing it.

Yep it's back to doing after I used it for a while and now it feels gritty/sticky. This is really ridiculous.I have never experienced this before

Is there anything I can clean the trackpad with that will fully strip off those oils or whatever embedded in it? Water won't do anything

Nevermind, did some searching around and a lot of people have experienced this problem. It's definitely not just a case of a sticky substance on the pad or anything.

Gonna take it into my apple store, hopefully they just replace the whole trackpad

This is so infuriating. I made an appointment to take it in today and now OF COURSE it stops doing it. I literally have tried everything to make it happen again and it just won't. The problem is that I know it isn't actually fixed. Sometimes it goes through periods where it stops doing it and then it comes back non stop for like 30 minutes.

If I take it into the store I won't be able to prove anything is wrong with it so they won't do anything about it and it will just be a wasted trip
