A few days ago, my laptop was broken. So I started using my dad's laptop. I think its a "netbook" but I'm not sure. I don't know the difference actually. Anyway... I use Mozilla Firefox, but while I was surfing, I realized that the connection working really slow. Most of the time, I write the website's link(like google.com, imdb.com...), hit enter but it says "Sunucu bulunamadı". I couldn't find the error in English, the translate must be something like; "page(or server) could not found". But after I press Ctrl+r it works, the website opens without a problem. So, I wonder why Firefox shows the error in most of the sites I try to enter.
Is it because of my connection really slow? But I don't think thats the problem, because when I was surfing on my laptop(the broken one), internet connection was pretty fast, I did not had any problems and I was using Firefox. I don't know whats wrong with this laptop. Could it be something about Firefox settings or something? Or is it a virus? I scanned with Malwarebytes' Anti-Malware and deleted 3 threats but its still not working properly. I did not scan with an anti-virus program yet, because I'm kinda confused with all those anti-something programs. I read that using two AV programs could cause problems. So, do I have to delete MBAM before I use AV program? Or MBAM is not AV program, so I don't have to uninstall it? Yes, I'm really confused.
By the way, I was checking some settings and I clicked Firefox/Tools/Options/Advanced/Network/Settings and I saw that "Use System Proxy Settings" was checked. I changed it to "No Proxy". I don't know if its important or not, but I think I have to write everything I did trying to solve the issue.
My other problems are, I suspect this laptop is being monitored and I forgot one of my hotmail addresses ID. But I guess I have to open separate topics for these?
I forgot to add that: The laptop(or notebook, or netbook..) is Windows 7 Home Premium.
Sorry for my English . If you don't understand anything, please tell me, I'll try to describe better.
