One free scan finds every outdated or missing driver and matches the right update for your exact hardware.Free scan · exact hardware matchTo remove suspected malware from a memory card, save only files you truly need, scan the computer that reads the card, then format the card. Formatting erases everything on it. If it is an SD-family card, the SD Association recommends its own formatter instead of a generic operating-system format tool. A clean card can be infected again if the connected computer is still compromised.
Before you start: treat the infection as suspected, not confirmed
Files disappearing, unfamiliar files appearing, or a card behaving strangely do not by themselves prove that it contains a virus. The problem could also involve the card, its adapter, compatibility, or the computer. Until you know more, stop opening files from the card and avoid copying its entire contents onto another computer.

If you need some files
Copy only the files you need, then scan them with current security software before opening or using them. A familiar file type, such as a photo, does not by itself establish that a file is safe. The cited guidance does not guarantee that files can be recovered or that any particular file is clean.
Scan the computer before formatting the card
A computer that is infected could write malware back to a card after it has been formatted. On Windows, open Windows Security > Virus & threat protection. Check for security-intelligence updates, then run an available scan; the app also provides more extensive and custom scan options. Microsoft explains that Windows Security uses security intelligence when scans run. A clean scan is useful, but it is not proof that every possible infection is absent. See Microsoft’s Windows Security guidance.

Format the memory card
Option 1: Format it in the camera or device
If the computer cannot format the card, use the camera or other device’s format option. Look in that device’s settings or storage menu and confirm that the selected card is the one you intend to erase. The exact menu wording varies by device. Formatting deletes the card’s contents.
Recommended Free Tools
Option 2: Use the SD Association formatter for an SD-family card
For SD, SDHC, SDXC, and SDUC cards, the SD Association strongly recommends its SD Memory Card Formatter over generic operating-system formatting tools. It says generic tools may not be optimized for SD cards and could result in lower performance. Check the page for current operating-system compatibility and instructions before downloading or using the formatter; versions and supported systems can change.

The association lists compatible PC card slots and USB SD card readers as interface options. A separate reader is not required if the computer has a compatible slot or the camera can format the card. Confirm that the interface supports your card. The formatter does not format the protected area on SD, SDHC, and SDXC cards.
If the card will not format
Do not assume that a format failure means malware is responsible. Check that a full-size SD card’s lock tab is not in the write-protect position; if you use an adapter, check its lock tab too. Note the exact error message and confirm that the reader or device is compatible with the card.

If files return after formatting or the card continues to behave erratically, the computer may be writing them back, or the cause may be card damage, compatibility, or another fault. The available evidence cannot identify the cause from those symptoms alone. Record the card type, device or reader, operating system, and exact error to narrow it down.
Check whether the problem returns
After formatting, use the card in its intended camera or device and watch for the same symptoms. If they recur, do not keep formatting the card as the only response: investigate the computer or other device that connects to it. Ask Leo!’s 2008 advice captures the distinction: “The card is easy to clean. Your system may not be.”
