So a few weeks ago I got "something bad" along with the latest Firefox download. I think they got hacked. There was this really crappy-looking search engine on it' its own tab that made me suspicious so I deleted it and reset default search engine to yahoo.Too late.
Then my USB devices became "invisible" - my SD photo cards and memory sticks didn't read. (They work fine on anhother PC) Win7 reported the USB ports as OK. So after mulling over this I flashed the BIOS and they came back! - for awhile. Now it's happening again. So there is "something" in my system.
I have run the latest version of Malwarebytes and after the deep scan deleted some low-level junk - toolbars, sweet, but nothing really deadly. I'd expect disabling the USB is a method of preventing use of a "rescue stick" with a linux OS and cleaner suite to kill it. Maybe whatever it was had been partially whacked when I cleared-out the bogus search engine.
Win7 Ultimate (64)is behaving normally, so I could also use SysInternal utilities if I knew where to begin looking and what it might be called.
I also ran DDS and read the list. Nothing looks unusual.
