Hi Paul
I also use Google Chrome with Wndows 7, but like others, without the problems you are having. I use, as Oompa Lumpa AKA Graham suggests, Malwarebytes in addition to my standard security program, F-Secure, as it also detects PUPS (Probably Unwanted Programs/Software) and frequently enables effective deletion of the offending software. This free software does not affect the running of standard security software progs as it is a stand alone and on demand prog which gives a second line of defence. Much of this unwanted software is included with what appears to be genuine progs and frequently includes extensions to your browser which you have to opt out of if you don't want them installed automatically, it can be a real PITA at times.
If you have already run Malwarebytes then please ignore my reference to it.
Cheers
Martin
