Thanks everyone for your replies although a lot of it is way over my head!

I have now got Kaspersky 2013 installed free from my bank but my computer is soooooooooo slow now that earlier trying to get the BBC news it took 45 seconds to appear and everything else seems to take forever as well.

I still have Malwarebytes installed, would this be working against Kasperski?

That is the problem with a free lunch. I always found KIS strangled the system, especially when installing software or scanning. I shifted to Kaspersky Pure 2.0 alongside Webroot SecureAnywhere complete which is cloud based, lightning fast and has turned out to be one of the best, so i will probably drop kaspersky Pure next year. You can get a free trial here http://www.webroot.com/customerSupport/trialRegistra... try it with Kaspersky shut down and be amazed at the speed, or run alongside and compare the performance.

the free version of Malwarebytes doesn't have a resident component, as I understand it. It scans when you run it. The paid for one has some sort of protection layer and at least one AV used to ask for it to be removed before it would install due to incompatibility.

You can only really run one proper AV on a system at once, but some other malware products may be complementary.

As Yarwell says, Malwarebytes only runs when you run it to clean up a virus - it has no background service and so won't be 'competing' with Kaspersky.

Like I said earlier, I have found Microsoft Security Essentials perfectly adequate and it has no slowing effect. Maybe try using something other than Kaspersky????

Thanks again for your advice and have been researching MSE which seems to have mixed reviews but for some reason my computer is working much faster this morning so will see how it goes and if it does start crawling along to such a speed that it is all but unusable I will have to change.
I wish I was about 55 years younger then I would perhaps understand all this stuff!

Age isn't really an issue - my son is 24 and only knows how to switch his computer on. Any problems and it's a call for his 60+ year old Dad!!
