What Is Adware?
Adware is the shortened form of “advertising malware”; it's designed to hijack the navigability of web browsers – throwing up unwanted adverts and redirecting web searches to advert pages.
The program is widely known in the cyber world as a modern-day PUP – Potentially Unwanted Program.
Typically, the unwanted pop-ups that suddenly appear on your screen while surfing the net are mainly associated with adware,. However these pop-ups are some times standard components of a website.
Furthermore, this program is slightly different from other forms of malware in that it does little or no harm to the host computer or inherent files.
Nonetheless, some adware are notorious for information theft. This category of adware is similar to “trojan spyware”, which is highly notorious for data theft and cyber-espionage.
Essentially, adware is used by advertising agencies, albeit illegally, to gather information about potential clients/customers or promote a particular product.
Adware Signs And Effects
As pointed out earlier, “advertising malware” is not like other forms of malware. Usually, an adware invasion provides less cause for worry, compared to the invasion of spyware or Trojans.
In most cases (if not all), this program does not impede the smooth-running of infected computers, except, of course, the nuisance created by the pop-up ads, as well as the web redirects.
Similarly, a typical adware reveals itself to the victim. And most times, it requests permission (usually in disguise) before accessing privileged information.
However, its revelation is in its effects – the pop-up ads, as there is usually zero indication or traceable record of adware installation on your device.
Common Sources Of Adware Infection
Adware lurks in various corners of the digital world, waiting to infiltrate your devices and bombard you with unwanted ads.
Here are some of the most common sources to be aware of:
1. Freeware and Shareware
While free software can be tempting, it often comes bundled with adware. During installation, some programs might sneakily install adware alongside themselves, often hidden within the fine print of agreements you might skip reading.
2. Infected Websites
Clicking on malicious links or visiting compromised websites can expose your device to adware. These websites might contain hidden scripts or exploit vulnerabilities to inject adware onto your device.
3. Malicious Email Attachments
Opening infected attachments in emails, especially from unknown senders, can be a gateway for adware. These attachments might disguise themselves as legitimate documents but actually contain adware hidden within.
4. Peer-to-Peer (P2P) File Sharing
Sharing files through P2P networks can be risky. Downloaded files, especially from unreliable sources, might be laced with adware waiting to be unleashed on your device.
5. Fake Software Updates
Phishing tactics can be used to trick users into installing fake software updates that are actually adware in disguise. Always verify the legitimacy of updates before installing them.
6. Mobile Apps
Even app stores, although typically safer, can harbor malicious apps containing adware. Be cautious when downloading apps, read reviews, and only download from reputable sources.
7. Deceptive Ads
Clicking on pop-up ads that promise freebies or claim to detect “viruses” on your device can lead to adware infection. Always exercise caution when interacting with online advertisements.
By recognizing these potential threats and practicing safe browsing habits, you can significantly reduce your risk of encountering adware and protect yourself from its intrusive and potentially harmful effects.
How To Remove Adware
Adware can be a nuisance, but don't panic! Here's a comprehensive guide on removing it from your device:
1. Scan with your Antivirus
Most antivirus software offers adware protection alongside virus protection. Run a full system scan to detect and remove any adware it might find.
2. Check Browser Extensions
Open your browser settings and review the list of installed extensions. Look for any unfamiliar or suspicious entries, especially those recently added. Remove any extensions you don't recognize or use.
3. Manage Installed Programs
Go to your device's control panel or settings (depending on your operating system) and access the list of installed programs.
Look for programs you don't remember installing or seem suspicious. Research them online to verify their legitimacy. If confirmed as adware, uninstall them immediately.
4. Consider Dedicated Anti-Adware
In some cases, more robust solutions might be needed. Dedicated anti-adware programs specialize in detecting and removing adware that might escape traditional antivirus software.
Consider using a reputable anti-adware program to eliminate stubborn adware infections.
5. Manual Removal (Advanced Users)
This approach is only recommended for advanced users as it involves modifying system settings and potentially deleting critical files.
If comfortable, research specific instructions for your operating system and the identified adware to manually remove its files and registry entries. Proceed with caution and back up your data beforehand.
- Clear your browser cache and cookies: These can sometimes harbor traces of adware.
- Change your browser homepage and default search engine: Adware might have altered these settings.
- Reset your browser settings: This can be a nuclear option, but it can also be effective in removing adware that has embedded itself deeply in your browser settings. Be aware that resetting your browser will erase all your saved data, bookmarks, and passwords.
- Be cautious with future downloads: Only download software from trusted sources and pay attention during installation processes to avoid accidentally installing adware.
To remove this program from your computer, you can use a standard malware scanner/remover or a versatile antivirus program like AVG. Check our Deal page for some of the best malware remover tools.
