Avira Premium antivirus is disabling automatically and won't update

Hello guys, annoying problem. Originally what was going on was I kept having the google redirect virus that was sending me to diff websites when I'd run searches. So I ended up going online and downloading a bunch of programs from various sites claiming to be able to assist in fixing it. Malwarebytes, super adware remover, spybot, among others were used. then at some point the problem went from the redirect virus to not being able to even get on the internet after a normal bootup. I had to boot up in safe mode and ended up reading enough to figure out that I thought all the programs I'd downloaded were causing complications, so I uninstalled a bunch of them and ran certain ones, and then my computer was back to working in normal mode and the internet working and all.

Now though, my antivirus that I always used, Avira Premium, it won't update and when I open it up it disables after like 6 seconds and says its deactivated. When I try to update it, it tells me "The following error occured:" and then has a picture of what looks like the # 10 but the 1 is a skinny arrow pointing up. I found a thread here on this site that was recommending to download combofix and disable all antivirus before doing so, but when I ran combofix it told me that I had trend micro internet antivirus running, even though I had already uninstalled that program repeatedly and it's not showing up on my program files list anymore.

Anyone know what's going on? Help? I can't run combofix if I can't disable trend micro, and I can't disable trend micro since I don't even see where it's installed or running.
