Thats correct i have all those software on my computer except for skype.
Yep, i had to use firefox as my default. Id prefer to use google chrome however after a couple of days of using it the search options change, as in, just the links would be given which would be underlined in blue, with no previews etc. Im guessing now that this virus/malware i have is the cause of it changing.
Nope, i have nt changed or added any new proxy settings. As far as i know, ive had this bug on my laptop for sometime now, maybe months, however i did nt realise it was anything of such until recently when a few odd things started to occur (no internet access via explorer, not been able to change or delete that address, changed settings in goggle chrome; but very subtle).
