I seem to have a very slow Download speed for the last couple of days @ 0.70/80 Mbps!! I suspect some sort of malware, but malwarebytes, Adaware, SearchBot S&D, and my AV scans are not picking anything up.They have all been Updated. It seems to be intermittent over a few days, then goes away before returning again? If i dis-connect the internet from telephone socket for a minute or two, then re-connect, i get normal speed for about 10 minutes before it slows again. I can repeat this process over and over, but this is not normal practice. What is it? Please Help!
