How does Advanced Calendar 2.0 work?

You have probably already realized that Advanced Calendar 2.0 is an updated version of Advanced Calendar adware.

Both of these programs are developed with an aim to gain money by advertising partner companies. For this purpose, it inserts tracking cookies into all Internet browsers that are installed on your computer. These cookies are going to track your activity - what websites do you visit the most, what kind of content do you explore, what search terms do you usually use and so on.

Moreover, this program can see what country do you live in, what is your IP address, e-mail address, and so on. This and similar data is required to find out what do you usually look for on the Internet. Based on the collected data, this app selects certain ads from its server and sends them for you.

However, when you see "Advanced Calendar 2.0 ads," "offer by Advanced Calendar 2.0," "Ads by Advanced Calendar 2.0" or similar advertisements, do not think that these ads bring actual and real deals. In fact, they are generally used to tempt you to click on them.

What happens next, is that most likely you are going to be redirected to Advanced Calendar 2.0 partner's website. Be extremely careful - most of such web domains carry questionable content. Be sure you do not agree to install any free programs from such sites.

In some cases, content from suspicious websites can be infectious or malicious. To keep your PC secured, computer security experts advise keeping a professional security program installed on the system. You can use or any other trustworthy anti-spyware and anti-malware program.

How did Advanced Calendar 2.0 hijack my PC?

According to spyware and malware researchers, most of potentially unwanted programs (PUPs) are spread via bundling.

This particular software distribution technique is simply a way to put several programs into one software package. For example, when you download a free program, it is most likely going to have several optional applications attached to it. Unfortunately, there is an only way to reveal whether your selected program is supplemented with additional freeware or not.

You need to glance over the Terms of Use document and look for statements about a promotion of third-party software. Next, you have to set Advanced or Custom (whichever is available) installation mode. If the software promotes third-party software, you should receive a list of suggested applications. Deselect these suggestions to avoid installing unwanted freeware.

If Advanced Calendar 2.0 PUP has already been installed on your system without your knowledge, you should remove it. Instructions how to do it are provided on the next page.

How to remove Advanced Calendar 2.0 ads

Uninstall first, then remove what stays behind, so the ads do not come back after a restart.

  1. Step 1: Uninstall Advanced Calendar 2.0 ads

    Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10.

    Sort the list by install date and find Advanced Calendar 2.0 ads, then choose Uninstall from the three-dot menu next to it (in Windows 10, click the entry and then Uninstall).

    Remove anything else installed on the same day that you do not recognise, because such programs usually arrive together in one installer. If the uninstaller opens a browser page with an offer or a survey, close it: the program is removed either way.

  2. Step 2: Remove it from startup

    Whatever Advanced Calendar 2.0 ads installed usually starts with Windows.

    Open Task Manager with Ctrl + Shift + Esc, go to Startup apps in Windows 11 or the Startup tab in Windows 10, and disable what you do not know, starting with entries that have an empty Publisher column.

    Open file location on the right-click menu shows the file, which helps you decide and tells you what to delete later. Disabling is safe: if something you need stops working, switch it back on.

  3. Step 3: Delete the folders left behind

    What the uninstaller leaves behind is usually in the user folders. Open File Explorer, switch on View > Show > Hidden items (in Windows 10 View > Hidden items), and go through %LocalAppData%, %AppData%, %ProgramData% and the two Program Files folders.

    Sort by Date modified and delete folders that appeared together with the problem and belong to no program you use. Folders with random names that hold .exe, .dll, .js or .ps1 files are the strongest sign.

  4. Step 4: Reset the browser

    Finish the browser part with a reset, which puts the search engine, start page, new tab page and site permissions back to their defaults and switches extensions off. Chrome: Settings > Reset settings > Restore settings to their original defaults.

    Edge: Settings > Reset settings. Firefox: Help > More troubleshooting information > Refresh Firefox, which also removes its extensions. Your bookmarks and saved passwords are kept, and the menus are the same on Windows 11 and Windows 10.

    Chrome Settings page with the Reset settings section open
    Chrome on Windows 11: Settings > Reset settings.

  5. Step 5: Scan the PC, then run the offline scan

    Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.

    Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices.

Avoid any unwanted government tracking or spying by going totally anonymous on the internet.

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings.

Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact - you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use for the data restoration process.

How to uninstall this ad-supported program from the system?

It is not necessary to say that adware programs can hardly be useful for you.

They seek to gain pay-per-click revenue in a vague way, and you should not waste your time trying to close these ads. The only way to get rid of them once and for all is to uninstall Advanced Calendar 2.0 virus.

You can do that manually - follow the Advanced Calendar 2.0 removal instruction below the text. Alternatively, install any anti-spyware software you like to automatically remove computer threats from your computer.

Questions about Advanced Calendar 2.0 ads

Can I safely uninstall Advanced Calendar 2.0 ads?

If you did not install Advanced Calendar 2.0 ads yourself and it is not part of your hardware or a program you rely on, yes. Uninstalling an unwanted program does not harm Windows.

Before you do, search the exact name and publisher to be sure it is not a driver tool, a printer utility or a game launcher with an odd name. Then remove it from Settings, Apps, Installed apps.

Ignore any offers or warnings in its uninstaller about losing protection or performance. Afterwards check Startup apps and your browsers for leftovers, and restart once to confirm that it does not reinstall itself.

How do I stop programs like Advanced Calendar 2.0 ads from being installed again?

Most unwanted programs arrive through installers, so the fix is in how you install software. Download programs from their official sites or the Microsoft Store, not from download portals or ads above search results. During setup, choose Custom or Advanced installation and untick every extra offer, including browsers, toolbars and optimizers.

Decline update prompts that appear inside other programs unless you know them. In Windows Security, turn on reputation-based protection and potentially unwanted app blocking. These steps would most likely have stopped Advanced Calendar 2.0 ads before it reached the app list.

Is uninstalling Advanced Calendar 2.0 ads enough?

Often, but not always. Uninstalling Advanced Calendar 2.0 ads through Settings > Apps > Installed apps removes the main part. Ad-supported programs, however, frequently arrive together with others from the same installer, and some leave a scheduled task or a browser extension behind.

After uninstalling, sort the list of installed apps by date and look at what else appeared that day, check Task Manager > Startup apps, and open the extension page in every browser. A Microsoft Defender full scan at the end catches leftover files.

My scan found nothing, but the ads continue. Why?

Because the source may not be a file a scanner looks for. Browser notifications are a permission stored in the browser, and many adware extensions are not flagged because they come from an official store.

Some ad-supported programs are only reported if you enable detection of potentially unwanted apps. So a clean scan does not mean the job is done. Check each browser's notification permissions and extension list by hand, and turn on Potentially unwanted app blocking in Windows Security before scanning again.

Did Advanced Calendar 2.0 ads collect my data?

Adware typically collects what it needs to choose ads:

  • the sites you visit
  • search terms
  • approximate location
  • browser and system details

Extensions with permission to read and change data on all websites can technically see everything on those pages, including forms. That is a privacy problem rather than proof of theft.

If you typed card details or passwords while it was active, changing the most important passwords is a reasonable precaution. Clearing cookies after removal ends the tracking sessions it may have started.

Can an adware pop-up infect my PC just by appearing?

No. A pop-up, a notification or a new tab is only a web page or a message. It cannot run programs on Windows by itself, provided the browser and Windows are up to date. Infection needs a step from you:

  • running a downloaded file
  • installing an extension
  • giving a stranger remote access

That is why scam pages work so hard to make you click. Close such pages with the tab's X or by closing the browser, not with buttons inside the page, which may start a download.

Why is my browser so slow since the ads started?

Each page now does extra work. An adware extension reads the page, decides where to put ads, loads them from ad servers and reports your visit, and that happens on every tab. Ad-supported programs add their own background activity.

Removing the extension or program usually makes the browser fast again at once. If it stays slow, open the browser's own task manager with Shift+Esc in Chrome or Edge and look for extensions using a lot of memory or processor time.

I let a "support technician" from an ad connect to my PC. What should I do?

Act quickly but calmly. Disconnect the PC from the internet first, so the connection ends. Uninstall the remote access tool they asked you to install and check Installed apps for anything else added during the call.

Run a Microsoft Defender full scan and offline scan. From another device, change your e-mail and banking passwords and sign out of all sessions.

If you paid by card, bank transfer or gift card, contact your bank or the card issuer immediately, and report the scam to the police. Do not answer if they call back.

Will Fortect remove Advanced Calendar 2.0 ads?

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 Advanced Calendar 2.0 ads, 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.
