Hi — good question. 's suggestion to use a free antivirus is a sensible starting point, but pick one that is actively updated and confirmed to support Windows Vista. Before installing anything, make sure Vista has the latest service pack and Windows Update is enabled; up-to-date system files matter as much as virus definitions.

Choose an AV that:

  • Clearly states Vista compatibility (32/64-bit) and still receives definition updates.
  • Provides real-time protection and automatic updates.
  • Has a modest memory/CPU footprint on older hardware.
  • Lets you schedule full scans and quarantine suspicious files.
  • Offers straightforward uninstall instructions in case you need to switch.

Installation and quick troubleshooting:

  • Uninstall any existing real-time antivirus first, then reboot.
  • Install from the vendor site, update definitions immediately, and run a full scan.
  • If the system becomes sluggish, enable any low-resource or silent mode the product offers.
  • Do not run two real-time antivirus engines at the same time — that causes conflicts and slowdowns.
  • Keep regular backups and schedule periodic full scans.

Note: Windows Vista reached end of support in 2017, so an AV helps but cannot substitute for an unsupported OS. If possible, plan an upgrade to a supported Windows version for much stronger security.

You can use AVG Anti-Virus Free Edition
That is a good one.
