I do not think you have a virus. Most people here think Apple is virus free (and I agree) ... but.
If you are doubtful and go checking for anti-virus protction, the best you can get is Sophos and / or ClamXav, the latter being free.
Warning. Do not download or have anything to do with MacKeeper or anything from Zeobit.

Considering there are zero viruses for OS X it's a waste of time and money and resources. There are a few trojans but they are 1000% different than viruses. Almost alll the antivirus applications for OS X tend to create more problems than they solve which is why I recommend no antivirus software. However if you must ONLY install ClamXav which is free, kept up-to-date and unobtrusive. I'd also recommend educating yourself by reading articles such as Thomas Reed's Mac Malware Guide, don't read articles from the antivirus vendors they're only trying to sell their products.

It's almost certainly not a virus (aka malware.)
First thing to try is to make a new location in Sys Prefs>Accounts. See BDAqua's instructions for doing this
If that doesn't help, this may be a DNS server issue. Test with OpenDNS, Level3.net or GoogleDNS to see which of these improves the speed.
In Sys Prefs>Network>Advanced>DNS enter these numbers above any others that may be there and hit Apply.

I'm still fairly new to mac, so all this jargon is like a different language to me. lol
I've tried to enter those DNS numbers and I can't see any difference.
I'm not sure if I'm doing it right

I've read the guide, and it's just my internet that's slow. He only talks about the whole computer being slow/shutting down. and Malware doesn't cause that. So I'm not sure where to go from here because the technician tested the lines and they were fine.... so yeah, i'm clueless lol

Are you using WI-FI? If you are, option-click on the Airport icon. What is the Transmit Rate showing there?
To enter new DNS numbers (Sys Prefs>Network>Advanced) click on the + button. You will get a new field in blue, as shown in the screenshot below. Enter one number there, then hit OK. You will be brought back to the main tab. Hit Apply. Go back to Advanced and repeat for the second number, then hit OK. You will be brought back to the main page and hit Apply again. You can reorder the way the numbers appear by dragging them. Not absolutely certain of this, but the numbers first listed will be the DNS servers used first; second will be contacted next. If you put all those numbers in (all three sets), you can then test which servers are the fastest for you by rearranging the list order.
DNS (Domain Name Server) is like the phone book. It translates names into telephone numbers. You can't dial a name. DNS servers translate site names into numbers. Some servers are better/faster than others.
Also be sure to turn off IPv6 in TCP/IP
To check that OpenDNS is working, go to http://www.opendns.com/welcome/

No I'm using cable - I've done as per your instructions. I've done a speed test and my internet speed is still around 1.16Mbps - when the technician checked it. The speed was around 8Mbps - so im not sure if it's to do with DNS, don't know.
But thank you

OK, do the other stuff. And what's this about the computer shutting down? And whatever browser you're using, test with another. If Safari, try Firefox and vice versa.
