I accidentally deleted my driver and now cannot connect to internet?

[444]

I accidentally deleted a software named something like 'Realtek Ethernet Controller' and it has a logo of a blue crab when I was deleting my overloading softwares. Can I redone load it?

Then when I went into Google Chrome and it showed the homepage but when I search for something or opened a new webpage, the internet is unconnected.

Another possible reason is that recently I have downloaded some softwares which brought a lot of advertisements and sometimes suddenly pop out some advertising website. And every time when I on my computer, loads of software windows pop out, for example: Reg Clean Pro, Whistler, PC cleaner, Systweak Support dock, my PC backup, etc. Honestly I really didn't know how all these many softwares came since in my memory I only downloaded 1-3 softwares which I thought they were useful, but then it ended up with all these softwares which I didn't even download and the advertisements. So I was thinking if they are some sort of viruses on the computer?

I am using TP-LINK

I am using Windows 7 Ultimate

I am using a PC

Please please please help if you can! Thanks!

try reinstalling your ethernet drivers. go to your laptop manufacturer's support website and under a section that may be titled drivers and downloads look for your laptop model's drivers. download and install, see if it works after that

he said he can't connect to the internet though, lol, if you have your CD installer than you'll need that to re-install it
