Recently I have noticed that when clicking on Google search results, arbitrarily, a link I open is redirected to various advertisement websites, if I go back one page, and click the result again, generally I will go to the result properly, again, this only happens randomly.
This is quite annoying, and worrying because I'm probably infected with something and do not know the extent of the harm. I did run ComboFix, it removed some files, but I'm using Firefox now, and still upon clicking a Google search result, I am randomly directed to an advertisement website. I also ran MalwareBytes, full scan, and was told that my PC was clean, 0 problems found.
I also would like to mention an off-topic "issue." Not sure if this is a result of an infection, but a week ago, I was accustomed to using CTRL+T or CTRL+SHIFT+T, just various shortcuts to make browsing easier. And usually if I was on Youtube, or on a Flash component in general, I could not use these shortcuts. Obviously, the fix to this was to click somewhere off of where the Flash screen was (or Youtube video, etc) and then I could execute the shortcut no problem. But recently, while browsing Youtube, I would attempt to click somewhere else, but still cannot use the shortcuts, the only way I can use the shortcut now is to click on the search textbox, not a huge deal, but very annoying when it's become habitual to just click anywhere besides the Flash video to make shortcuts work. I should also mention that prior to this issue, my Flash just began to operate rather faulty. I ended up uninstalling Flash, and reinstalling it because of this. And after the reinstallation these shortcut errors have been occurring. Also, after the reinstallation I noticed in Task Manager that Firefox is no longer putting all of the memory on "plugin-container.exe*32" but instead now I have noticed two new processes running whenever I use Flash related things, FlashPlayerPlugin_11_3_300_262.exe*32, again, there is two of these running at the same time, one uses significantly more memory than the other, the other typically stays under 10,000K.
Again, not sure if that issue is even worth mentioning, but it is something that is completely different from what I usual do/expect, so I decided to mention it.
