Inexplicably logical problem (optical fiber, wi-fi)

[margaret.creek.20]

Is it possible for the browser to display incorrect information on some pages, and some correct, in the form of text, by a single use of Google, in the same language? For this simultaneous, strange behavior of email accounts and instant messengers, type AIM? When seemingly nothing extraordinary happens? Using two different computers and browsers connected to the same network?

Can it have a relationship with a hacker attack?

Thank You for Your answer.


P.S.: Sorry for my bad English.

While there could be a malware problem, it could also just be some improper settings on one of the computers.

You should scan for malware on the computers on the network with both an antivirus and a free version of Malwarebytes as a precaution in any case.

Yes some of this stuff is, I say tentatively "normal." All software have bugs, and unless you and your friend have the EXACT same thing, software version etc (highly unlikely), u may see different behavior, but do be aware of malwares. Anything that pops up and startS asking you for password, personal information, call this number etc, YOU GOT A PROBLEM.

The program has detected a few malwares. This must have occurred, during the recent download of files, from various locations. Moved to quarantine.

But still on many websites, information is displayed - top speed internet in Korea 26.8 Mbps. Not North ; )

Recently I received a message from GM that someone in the USA tried to log in to my account and know my password. I changed them. I scanned the SUPERAntiSpyware laptop and found something else. I suspect that the person (one or the other) could access the full laptop and write messages from messengers and e-mails. I will scan drives also Avast Anti Vir and
Sophos Virus Removal. I'm changing all the passwords.

Potentially, it could have access to other devices using home Wi-Fi.

Any extra advice, beyond the obvious?

Keep cleaning malware, look for antiviruses with several free versions (the MS antivirus isn't bad either) and then move on.

As jsmithepa says, some of the things are NOT unusual due to minor configuration differences, but you need to sort out the problem stuff first.

And while you are at it one other free and very powerful cleaning tool is to BOOT from the free version of Kaspersky Rescue Disk 18 from HERE and run it to find rootkits and pretty much all other forms of malware and virus out there.

I downloaded the program, but nowhere on the C or D drive, I can not find it. Only an additional KRD drive, is displayed to me, in which there is no application, in any of the folders. I downloaded it again from another source and the problem is the same. Win 8.1 (64 bit).

In the future, think about following the OS IMAGE method. I never bother with a viruscan, cleaner blah-blah never EVER, life is too short. when things are working perfectly, like shortly after a fresh install, I OS IMAGE my C: (that's where most attack occur), put that puppy aside, and as soon as something "weird" I restore the image, back in business 15 minutes, like nothing happened, a true time machine. Turn Windows and all other updates to manual, their latest may not be so greatest, keep it all under YOUR control.

You have to download it on another computer and create a boot CD or USB -- read the on site directions, it boots up your computer in a Linux build to prevent low level rootkits and the like from running, then cleans extremely well.

And yes, sometimes a clean install can be faster, but at the cost of all data. After a good cleaning, I would remove the needed data and then do a clean install as any significant malware usually messes with registry entries.
