Antivirus Software

Download antivirus software — ESET NOD32, Kaspersky, Avast — free full versions with install guides.

Virus and malware protection. Install exactly one: two antivirus products will detect each other and measurably slow the machine. What matters most is that it can keep updating its definitions.

How to choose from this category

  • One product only, and fully remove the previous one before installing another.
  • Confirm it can still update definitions — one that cannot is close to useless.
  • The built-in Windows Defender is decent if kept current.
  • Check the performance cost — some suites noticeably slow mid-range machines.

Downloading and installing

Every page in this category follows the same shape: version and file size in the side panel, the download link and its mirror in the middle, and step-by-step install instructions below. If the file arrives as .rar or .zip, extract it with WinRAR or 7-Zip first — any archive password is shown in the download box.

If your antivirus objects during extraction, pause real-time protection, extract again, and switch it back on once the install has finished.

FAQ

Can I run two antivirus programs at once?
You should not. Each scans the same files and flags the other as a threat; the machine slows sharply and protection can fail on both sides.
Is Windows Defender enough on its own?
For ordinary use where you are not installing software from unknown sources, yes. If you download and install frequently, an additional on-demand scanner helps.
It deleted a file I need.
Restore it from quarantine and add an exclusion — but be confident the file is genuinely from a source you trust.
