I have noticed a few weeks/ month or so ago, that the 'new tab home page' on both of the web browsers I regularly used had started coming up with something called globa search. (i.e. when opening a new tab in the browser, the page that was automatically shown on the new tab was this globasearch thing)
At first, I thought this was just a change Mozilla had made to Firefox, but then I noticed it also happened in Chrome. I also noticed that this seemed to coincide with my computer becoming very slow and unresponsive.
After doing a bit of research, it seems this globasearch thing is a virus that I must have picked up from somewhere... I had run a few antivirus scans (using F- Secure Internet Security, and also downloaded and ran an Ad-Aware scan), but neither of these picked up any viruses, so I wasn't sure what was going on.
I've had a quick Google of how to remove globasearch from my computer, but every site I've looked at is telling me to download and run some 'spyware removal tool'. I'm not sure that I trust these sites... there's just something about the feel of them that makes me think that they're not genuine, so I'm reluctant to download the tools they've suggested.
I was just wondering if anyone on here knows how I can remove globasearch from my computer, since neither F-Secure nor Ad-Aware seem to be able to?

Ok, I ran a scan using Malwarebytes as suggested, and it removed a few threats (all of the ones it found), and told me to restart my computer. I did that, and when I then opened my browser, and opened a new tab, I was still given the globasearch page... Any other ideas as to how to remove this?

Ok, having run both Malwarebytes and Hitman separately, and also restarted my computer, when I open a browser, I'm still having the same trouble with it being ridiculously slow/ unresponsive (for example, while typing in this comment, I type a few words, and it takes about 5 seconds after I've stopped typing for those words to be displayed in the text box). Also, when I open a new tab, I still get this globasearch thing, so whatever malware has been removed, clearly neither of the tools have found this globasearch virus/ malware. Any other ideas as to how I can get rid of it?
