An anti­virus scanner is the most important tool for virus removal. You install the anti­virus on your device and it starts to monitor incoming internet traffic and the sites you visit. If your virus protection detects any­thing suspicious, it alerts you and catches malicious soft­ware. With reliable anti­virus soft­ware, you can also run a virus scan to check your whole device or individual files for malware threats.

Malicious soft­ware, or malware comes in different forms. Computer viruses are only one type of malware. The common goal of viruses and other online threats is to infect your device, such as your computer. After the malware infects your computer, it may seek to corrupt and destroy files, steal valuable information and money, or spread further into other devices. These malicious threats are used by online criminals and hackers for financial gain, espionage or plain mischief.

F‑Secure’s free online virus scanner works on your Windows PC. However, there are viruses and other malware that can infect your mobile devices too. Use reliable malware protection to remove viruses and protect your smart­phone or tablet from future viruses.

Although many free malware removal tools can catch viruses lurking on your computer, they do not provide active monitoring and real-time protection that keeps your device safe against malicious programs at all times. Unlike free malware removal, a premium anti­virus with frequent updates catches the most recent cyber threats. F‑Secure Total’s virus scanner stays up-to-speed with new harmful soft­ware that free tools might miss. You can clean viruses from your devices with a quick scan or a more comprehensive virus scanner.
