Key signs of computer virus infection: What to watch out for

September 26, 2025  13:49

Viruses and malware can secretly infiltrate a computer, reducing its performance and threatening data security. Svyatoslav Pegov, head of the Center for Sports Programming and Esports at Ufa University of Science and Technology, told Pravda.Ru how to recognize infection and protect against threats.

Main Signs of Infection

According to Pegov, the first and most obvious signal is slow computer performance. If the device starts taking noticeably longer to complete tasks, it may indicate a virus. Other alarming signs include:

Unusual notifications and pop-up windows: messages appearing without reason. Suspicious processes in Task Manager: press Ctrl+Shift+Esc to open Task Manager and check the “Processes” tab. If you see unfamiliar programs consuming CPU or network resources, it’s a red flag.

“You see processes you don’t recognize, and they’re putting a load on your computer. That’s a clear sign of infection,” the expert emphasized.

How Do Viruses Get onto a Computer?

Pegov noted that most malware comes through fake links distributed by scammers in emails, messengers, or on websites. Clicking on unverified links is the main mistake users make.

“Never click links if you’re not sure of their source. This is the most common infection route,” he warned.

In addition, the Russian Ministry of Internal Affairs’ Office for Combating Illegal Use of ICT reported that scammers often use mining viruses, which secretly mine cryptocurrency while overloading the victim’s computer. This reduces performance and accelerates hardware wear.

How to Protect Yourself

To keep your device safe:

Check links: use antivirus software or services like VirusTotal to verify URLs. Keep software updated: ensure your antivirus and operating system are up to date. Monitor processes: regularly check Task Manager for suspicious activity. Use strong passwords and two-factor authentication. Download files only from official sources. In Short…

Slow performance, strange notifications, and unknown processes in Task Manager are clear signs of a computer virus infection. Scammers use fake links and mining viruses to harm devices. Simple precautions, such as link checks and keeping antivirus software updated, will help protect your computer from threats.
