What are the signs that my laptop has a virus?
A laptop infected with a virus may exhibit several telltale signs. Common symptoms include slower performance, frequent crashes, and unexpected pop-up ads, even when you’re not browsing the internet. Additionally, you might notice unfamiliar programs starting automatically, or your browser being redirected to strange websites. If your laptop’s antivirus software is disabled without your intervention, that is another strong indicator of a possible malware infection.
Another sign to watch for is unusually high CPU usage, which can be checked through the Task Manager. If you notice that your laptop is working hard despite doing minimal tasks, it could be a result of malicious software running in the background. Lastly, if your files become inaccessible or if a ransom note appears, it’s crucial to take immediate action to remove the virus.
How do I perform a virus scan on my laptop?
To perform a virus scan on your laptop, first, ensure that your antivirus software is up to date. Open your antivirus application and look for an option that allows you to run a full system scan. Depending on the software, this option might be labeled as “Full Scan,” “Complete Scan,” or “System Scan.” This process can take some time, especially if you have large amounts of data, so be sure to allocate enough time to let the scan complete.
If you do not have any antivirus software installed, consider downloading a reputable program or using a free online virus scanner.
