I have a constant issue with banner ads and pop up advertising even though pop ups are disabled, after much trying I have found that I am receiving malvertising as I also get banner ads in Wikipedia. I have tried many different malware and anti virus software though none seems to be able to recognise the threat. Because of this issue, in Task Manager cpu is always higher than 8/9%, memory is always past the 25%, disk is sometimes at 0% though mostly jumps up to 100%. Programs are constantly crashing and I can't watch videos as the page crashes. What should I do?
