Re: Off topic on PC Popups
¿ªÔÆÌåÓýDan,
If I remember the location of host file changed few times with the version of windows. ? So you will have to figure it out.
Normally HOST file should be empty of entries. ?When you type ¡°Google.com¡± your DNS server should tell your computer what is the numerical address of ¡°Google.com¡±. ? But some nefarious site might enter that Google goes somewhere else.
Oh another way they use host file is to enter 127.0.0.1 (your own computer) for popular sites like Google.com and have a fake web servers that send your browser those pop-ups. ? Here¡¯s a brief writer-up about host file hijacking?
?= ?= ?= ?= ?= ?=?
While I was typing this, there¡¯s also the possibility of DNS hijacking. ? Your dns entry is normally your own ISP (or one of the famous DNS). ? But sometimes an attacker might enter their own DNS server address so it will tell your browser to
go to their own websites (to make pop up happen).
?= ?= ?= ?= ?= ?=?
DNS hijacking and host file hijacking would probably have the symptoms you¡¯ve described (multiple browsers all showing pop-ups, without any virus being installed or detected).
I hope it works out and I didn¡¯t send you down a bad rabbit¡¯s holes.

Re: Off topic on PC Popups
Jong, Thanks, I think I have an idea what you are saying but can I just do a search for the HOST file. Where is it located, under Program Files? wings515 On Tuesday, April 15, 2025 at 09:51:06 AM EDT, jong kung via groups.io <jongkung01@...> wrote: Dan, Look in your HOST file and see if there¡¯s a redirect of famous sites like Google to a pop up server somewhere. ?I had this happen to me once. ?

Re: Off topic on PC Popups
Mike, Thanks for the reply. First I'll check the extensions and see if any are the cause. Second, because an older version of TeamViewer was on another friend's pc, I opted to install TV15 on this problem pc. During the 55 minute Malwarebytes scan TV kept the connection. Maybe it's because it is rev 15. I looked at the latest version of TV and was not impressed. wings515 On Tuesday, April 15, 2025 at 09:42:55 AM EDT, C.

I have seen pop-ups occur as the result of some installed browser extensions or add-ons. You can go into the browser and turn off all the extensions and see if the pop-ups stop.

Re: Off topic on PC Popups
You will only be transferring the user¡¯s personal files, music and photos. The computer will have a new OS and you will be installing new apps, so it is very unlikely that you will transfer the infection. Mike Stone

I did see some posting about resetting Chrome to factory default but since it is also no Edge, I don't give that much credit. One user called McAfee and they stated what he is seeing is NOT a McAfee popup. So it must be some other hack. I'll try on Monday to install Malwarebytes to see if there is a change.

controlling mosfet biasing directly in the circuit question
Hello,I have created a circuit shown below in ltspice using tsmc 180nm mosfets.
unlike the standart way where we bias the mosfets using the large signal furmulas ,I would like to bias the M3,5,1,2 into saturation while M4,6 needs to be linear using charactersitics plots . How can I make these setting in the circuit below? Photos and Ltspice files are attached. Thanks. ?
