Google Chrome from time to time gives out strange links that open by themselves, and it is difficult to close them. What is the reason?

Question

Google Chrome

Now more and more often suspicious links are opened through Google Chrome, links with strange ads, or even with dubious content. Reinstalling the browser didn't help.
In this regard, I have questions:
1. What is the reason?
2. How is it treated?
3. How to protect yourself from this?
4. And how to prevent the recurrence of a similar situation?

Answer 1

Leftist sites/porn sites, strange software (with lots of adware), leftist antiviruses, etc. All this leads to your situation, regardless of the browser.
I recommend that you reconsider how you use your computer.
1. Reinstall Windows clean.
2. Create 2 accounts, an administrator account and a regular user account.
3. When using a computer, use a regular account and prohibit the installation of everything.
4. Never install any software from well-known software dumps, where all the software is hung with a terrifying amount of adware, malware and other trojans.
5. Don't use weird antiviruses.

Answer 2

My answer is the same: try Firefox.
Google chrome slows down wildly, what could be the reason?
In your screenshots, the Avira antivirus has a closed umbrella in the tray for some reason. But does this mean that protection is disabled?
It is necessary to treat the virus, only then to demolish chrome completely by deleting the folder manually. Then it will work.
If it does not help, you can try to demolish Avira and install Avast.

Answer 3

AdwCleaner, Malwarebytes programs work well against advertising links. Antivirus against ads, as a rule, is helpless. If ads appear when you launch your browser, take a look at the launch shortcuts. Often, a left link is written in the shortcut or a file with the .bat extension is launched. If some time after launch, then you need to look at the Task Scheduler for suspicious tasks. Also inspect for suspicious plugins in the browser.

To clean, you need to use the appropriate software. It was recommended above.
In addition to him, there is also Spybot Search and Destroy .
But not the fact that it will give 100% result. There are tricky cases, and in any case, you will need to look at the list of startups, check the list of running processes, look at browser extensions, network settings.
Partially, HijackThis can help! , but there is a time-consuming algorithm - logs are taken for typical places of vulnerabilities, then you look for the appropriate forum, post logs there, and they tell you where to look and what to do.
Naturally, check the antivirus, as again wrote above. Works \ does not work, are the databases fresh? It does not hurt to scan everything at the download stage. You can try to use alternative antiviruses for this (for example, cureit!).
If that doesn't work or you're too lazy, you can use the new Win8 feature called Reset (google reset windows 8). Nuance - if win8.1 is installed by upgrading win8, you may need a subsequent re-upgrade (in this case, reset to the original win8). It is done in a couple of mouse clicks, easier than reinstallation. You can do without it, but sometimes you have to clean up a lot of things and where there is a risk of missing something.
ATTENTION!
Before any operations of this kind - if there is no fresh data backup - do it!
And in the future, in order to prevent the repetition of history - do not go to bad sites (the badness of a site is not determined by the content, by the way), install an ad cutter, periodically scan with anti-malware, and not just an antivirus, do not install bad software, install UNCHECKY , but nevertheless when installing any software, check the presence of checkboxes about "appendages" and carefully read the buttons, do not "catch" on the bright green download buttons on sites when there is a small link with the same name nearby, read the address where the link leads before clicking it (say , if you download a torrent file or a book, and for some reason the download link leads to some exe - it's a trap!). In general, turn on the brain, without it in any way.
Well, yes, after the next reinstallation and installation / configuration of the basic software, make a disk image, then in such situations it will be easiest to deploy it in five minutes and work on.

Answer 5

Other browsers \ computers - the same problem? If so, do you have a home router? If yes, then update the firmware from the manufacturer's website. If there are no updates, install the same one. The problem may be in him if he was chuckled outside.
If the problem is not in the router, but in one browser, then one reinstallation is not enough. Create another user profile, in another directory, disable all extensions, and clear all temporary files, cache for example.
Next, have you tried any antivirus? And look at the same time what you have in hosts, at the same time you can stick Yandex dns's, those that are under the antivirus filter.

Answer 6

Stop rummaging through warese and porn, and the "links" will disappear by themselves.

Answer 7

Greetings. It's been a long time, but I've just come across this myself. I generally agree with the author of the answer, but this is not the real reason. Disabling the GMarkt extension worked for me.
