Final answer:
Adware can be suggested by sudden pop-up ads, redirects to unfamiliar sites, slow browsing speed, and changes in the browser's homepage or search engine. An antivirus program should be used to remove adware.
Step-by-step explanation:
When browsing the internet, certain symptoms can indicate that adware might be affecting your system. Adware is a type of malicious software designed to display unwanted advertisements and potentially collect data without your consent. Here are the signs that adware could be at work:
Sudden pop-up advertisements while browsing, which can interrupt your online experience unexpectedly.
Redirects to unfamiliar or suspicious websites, which might occur when you click on a link or sometimes even without any action from you.
Experience of slow browsing speed despite having a stable network connection, which can suggest adware is using resources in the background.
Unexplained changes in the browser's homepage or search engine, which indicates that adware has altered your settings to drive traffic to certain sites.
It's important to run a reputable antivirus or anti-malware program to remove adware and protect your device from future infections.
