According to tech experts from the cybersecurity news website NoVirus.uk , potentially unwanted applications, including adware-related software, are spread through rogue web pages.
Unwanted content often comes injected into a link which can be found in a potentially harmful website. If the user likes clicking on every site he/she sees on the Internet, the risk of being infected by adware and other PUPs increases. So, make sure you avoid visiting pages that are unknown to you.
To continue, adware-related programs can be avoided in other ways too:
- Use the Custom installation mode. Once you install software from free sources, you will avoid the risk of secret infiltration by using this mode. Besides, it lets you control all incoming downloads.
- Install a reputable antivirus tool. Experts recommend computer security programs for every single user. These automatical tools make sure that the system is protected 24/7.

Uninstall every entry from the day the trouble began that you did not install on purpose, for example a download manager, a converter or a browser you never chose.

Questions about Better History virus
How do I stop unanalytics.com from opening?
Find and remove whatever opens it. Start with the browser's extensions page and remove anything you do not remember adding. Next, open the notification settings and take away permission from sites you do not recognise.
Then check Settings > Apps > Installed apps for programs added around the day the redirects began, and uninstall those. Restart the browser and test a few links after each step.
If unanalytics.com still appears, reset the browser, which restores the default search engine, start page and permissions without deleting bookmarks or saved passwords. Redirects that survive a reset in every browser point to a program in Windows, and a full scan is the next step.
Should I worry about redirects to unanalytics.com?
Worry less about unanalytics.com itself and more about what keeps sending you there. A single redirect from a free streaming or download site is normal and harmless once the tab is closed.
Repeated redirects on sites that used to work fine mean something in the browser or in Windows changed, often an extension or program installed alongside other software. It may also collect the pages you visit. Remove the cause with the steps in this guide, and do not act on anything the redirected pages ask:
- no Allow clicks
- no downloads
- no calls
If you already did one of those, the matching section of this guide explains what to do next.
Why does Better History virus show me ads?
Because that is its whole purpose. Better History virus is an adware extension, and its operators are paid for every ad it displays and every click it gets. In this case the ads take the form of redirects through ad pages.
They are chosen by ad networks that accept almost any advertiser, which is why so many look like warnings or prizes. The ads are not a sign that your PC is broken or infected with something worse; they are a sign that something on it, or in the browser, has permission to advertise. Removing that permission or program stops them.
Do I have to clean every browser?
Yes, if you use more than one. We saw Better History virus in Chrome, Edge and Firefox, and each browser keeps its own extensions, notification permissions and settings. Chrome and Edge share the same extension format, so one installer can add the same adware to both, while Firefox has its own add-ons.
Check every browser on the PC, including ones you rarely open. If you sync a browser with an account, clean it while signed in, so that the removal reaches your other computers rather than the adware returning from them.
How do I know the ads come from Better History virus?
Look for redirects to unanalytics.com. That is the trace Better History virus leaves, and it shows up as redirects through ad pages. Ads that appear on every site, including ones that never carried ads before, point to something on your PC or in the browser rather than to the sites themselves.
A quick test is a private window, where extensions are off by default: if the ads disappear there, an extension is responsible. If they appear even with the browser closed, the source is a notification permission or a program in Windows.
Can adware slow down my PC?
Yes. Adware runs in the background, loads ad scripts, opens extra tabs and contacts its servers, all of which use processor time, memory and bandwidth. Ad-heavy extensions also slow down every page, because they inspect and change it before you see it.
The effect is strongest on older PCs and when several adware programs arrived together. After removal, restart the PC and check Task Manager for anything still using a lot of resources that you do not recognise. Speed usually returns to normal once the ads stop.
Does adware steal passwords?
Ordinary adware is built to show ads, not to steal logins, and most of it never touches saved passwords. The line is blurry, though. Extensions that can read every page could capture what you type, and adware ads sometimes lead to phishing pages that ask for passwords directly.
If you entered credentials on a page reached through an ad, change that password from a clean device and turn on two-step verification. Otherwise, removing adware extension and clearing cookies is usually enough.
I clicked on one of the ads. Am I infected?
Probably not. Clicking an ad usually only opens a page, and a page cannot install programs on an up-to-date Windows PC without your help.
You are at risk only if you then downloaded and ran a file, allowed notifications, entered card or login details, or called a phone number shown on the page. Delete any download and run a full and offline scan.
Change passwords you typed, from a clean device. Call your bank if you gave card details. If you called a number or allowed remote access, see the next question.
An ad showed a phone number and I called it. What now?
The number belongs to scammers, not to Microsoft or an antivirus company. If you only talked, hang up and do not call back. If you let them connect to the PC, disconnect it from the internet, uninstall the remote access program they used, such as AnyDesk, TeamViewer, ScreenConnect or UltraViewer, and run a full and offline scan.
If you paid or gave bank details, call your bank at once on the number printed on your card. Change any passwords you typed while they were connected, and report the call.
Will Fortect remove Better History virus?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Better History virus, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
