I have downloaded at least 6 anti-virus suites, and everyone of them has made changes on their own. These were top rated programs. Norton, Bit Defender, Avira, and others. And most were the devil to try to uninstall. They hide the uninstall program under some strange name or part of the program. I just spent a scary hour trying to uninstall Avira. It informed me that "it could not be uninstalled because I needed a virus control program. It also asked me for administrator rights. I finally got it out thru some aspect that wasn't the main program. All of these programs tried to put software and changes of their own on my computer. One asked me if I wanted to make internet explorer my default and use opera. I clicked 'no', yet it put up a window anyway telling me that these were now my defaults. It was a window without a way to x out except to accept. All of the programs used these windows that you can't x out of. All of them wanted to speed my computer, and make all kinds of other changes they called tune ups, ect. I had a hard drive die, have had two techs and spent days for a month fixing this damn computer, and it works good. I just want what used to exist, an antimalware program that changes nothing, just scans and gives online protection. I don't want it to tune anything, defrag. anything, accelerate anything, or take over my computer. Can anyone suggest a decent, legit program? As well, what is going on? Everyone of these programs were almost impossible to remove and imo act more like viruses. Do I have some kind of virus that is causing this?
