Losing internet connection after 5 mins.

I had some problems with a virus on my pc earlier this week but have since sorted the problem. I have to PCs wired to the same router and after 5 or so minutes browsing I lose my internet connection on one of them. If I switch off the router for a couple of minutes and then back on I'll get a few more minutes of browing before I recieve the page load error. Filters are present in the only phone line connection. Any help would be gratefully recieved.

Have you tried switching the two ports that the computers are in? It's rare but a port can go bad and cause that problem.

Also, are you 100% positive that the virus problem was taken care of? Most of the time an infection does cause connectivity problems, you might still have something lingering around in your computer.

I've tried switching ports but no success. I suppose it is possible there is still something on the PC somwhere although I've scanned with avira, eset, malwarebytes and have nice looking hijack this logs.

It could also be the NIC inside your pc but I agree if you just got rid of a bug, you may still have damage related to that bug. Just in case this bug got into your networking try this. Goto device mgr and delete the driver for your NIC. Then reboot the pc and let it reload the driver. This will reload the NIC drivers and essentially default all your network settings.

You might also try another NIC. In rare cases it might be a cabling issue as well so consider swapping cables just to make sure you haven't forgotten anything.
