Hi, this problem has been sticking to my laptop(HP Pavilion dv6-6003tx) for about 2 months now. At first, i thought it was a virus after accidentally downloading some add-ons and it was called something like Anti-phishing file bulldog. It changed my homepage and i got redirects to their search engine. After doing whatever i can and to no avail. I had it reformatted twice but the problem remains. Which led me to believe that its a hardware issue. It doesn't matter what browser i'm using as long it is my default browser it will open let it be chrome,ie or opera. If i'm browsing websites and stuff, it would not happen. However, when i'm playing games the temperature would be about 90degrees and the fan would suddenly have this intense spinning and the browsers would just start opening. It won't stop until after 5 minutes and if i go back to resume my game, it would happen again in intervals of roughly 2 to 5 minutes. So yea this is roughly the hell i'm going through. I have had it sent to a repair shop but the tech couldn't identify the problem and couldn't conclude whether it was a virus that still stayed or it was a hardware issue. He did pointed out that the south bridge of the motherboard is pretty unstable which is the cause of the high temperatures and that the high temperature causes software to open. But why browsers?, he said he is not sure about that and that this is the first time he is seeing something like this. So i had him turned down because he wasn't really sure what the problem was caused by and if he was to change some part of the motherboard it would cost about $157 but i was not convinced because what if its not gone after changing.
I kind of gave up on this laptop already as i have really gave it my all over a span of 2 months. It has caused me real mental torture but it still bugs me that i'm unable to identify what actually caused it. So please if there are any solutions to what causes this, i really hope we can put an end to this soul crushing problem and also thanks for reading this whole chunk, and i thank you in advance for any help.
1)I did split some ribena onto my keyboard but it happened like early january this year and this problem showed itself only at the end of march so i don't know if its related.
2)My keyboard has a shortcut key to open a browser.
3)Been to bleepingcomputer as i thought it was a malwarer issue but the techs there went through my logs and couldn't identify any virus.
4)The number 2 key would sometimes spam itself and would only be stopped after i press 2 again.
5)The browser spams used to open to the file bulldog search engines however, after a period of time, it just opens up my homepage and furiously refresh it. I can only slowly wait for about 5 minutes and wait for it to stop itself. Also, the more i try to close its as if its retaliating and it opens more.
