My Mozilla Firefox, Internet explorer and steam (Chrome is ok) have been acting very strangely the last few days. Every now and then I get a new tab opening with a fake adobe flash updater. I know it's fake as it's already up to date. Also, in Firefox when I go to some ordinary website it constantly says "connecting" and has a spinning/loading icon next to it even though the page has fully loaded and it says transferring data to "www.x" whatever sites. I've reinstalled the programs, disabled/removed add-ons, and also ran malware/virus software such as hitman pro, adwcleaner, RKILL etc and removed any programs I though might of been making this happen but NOTHING has helped the problem. I've also used a restore point from before the problem started but it didn't help.
Please don't tell me 'download and run' this that and the other unless you are 100% sure it will provide a solution to the problem.
Thanks in advance.
