sam.gov attachment virus scan failed: how to fix it

A sam.gov attachment virus scan failure usually means the file is corrupted, password-protected, or in a format the scanner cant read. Re-export the file as a clean PDF with no protection and upload again. If a clean PDF still fails, the scanner service itself may be having a bad day, so wait an hour and retry.

When to use this skill

• Attachments fail with a virus scan error
• Clean-looking files get flagged

When not to use this skill

• The upload fails before any scan runs (a size or session issue)
• Your file actually contains macros you need (flatten them first)

Tool compatibility

sam.gov bid attachments. Antivirus scanning on upload. Related area: business SaaS platforms and vendor portals. Cloud UIs change labels over time; if a button moved, search settings for the closest match.

Before you start

• Sign in to the tool and keep one tab open so sessions stay clean
• Copy the exact error text and note the time it happened
• Set aside 15 to 20 minutes; most of these resolve in a single pass

Quick diagnosis

Make sure this is the right skill before you invest the 15 minutes.

• If you are dealing with attachments fail with a virus scan error, start at step 1 below.
• If instead the upload fails before any scan runs (a size or session issue), stop here; you need a different skill.
• If neither quite matches, compare your screen against the verbatim error block at the top; that block is exactly what this skill covers.

Fix it in steps

1. Remove any file protection

Open the PDF and remove passwords or restrictions, then save a clean copy.

Expected: the file opens without prompting for anything.

2. Re-export as a plain PDF

Export the document fresh as a standard PDF with no embedded scripts or forms.

Expected: a simple, clean PDF file.

3. Re-upload the attachment

Delete the failed attachment and upload the clean file.

Expected: the virus scan passes and the file is accepted.

4. Wait and retry if it still fails

If a clean PDF fails twice, wait an hour and try once more before escalating.

Expected: scan passes, pointing at a transient scanner issue.

Confirm each step worked

Run through this checklist before moving on. If a check fails, redo that step instead of pushing ahead.

• Step 1 (remove any file protection): Expected: the file opens without prompting for anything.
• Step 2 (re-export as a plain pdf): Expected: a simple, clean PDF file.
• Step 3 (re-upload the attachment): Expected: the virus scan passes and the file is accepted.
• Step 4 (wait and retry if it still fails): Expected: scan passes, pointing at a transient scanner issue.

Quick recap

1. Remove any file protection
2. Re-export as a plain PDF
3. Re-upload the attachment
4. Wait and retry if it still fails

Still stuck?

Gather three things: the exact error text, the time it happened, and what changed just before it broke. Check the vendor status page for an active incident. Then open a support ticket with those three things; it cuts the back-and-forth in half. For agent runs, attach the last 50 lines of the agent log too, since the loop or timeout signature in the log usually names the cause.

Variant phrasings

sam.gov virus scan failed attachment

Clean PDF, no protection, re-upload. If this matches what you saw, the steps above apply as written.

attachment rejected virus scan sam.gov

If clean files fail repeatedly, the scanner service is likely degraded. If this matches what you saw, the steps above apply as written.

Why it happens

The scanner cant inspect password-protected or malformed files, so it fails closed and rejects them. Complex PDFs with embedded objects sometimes trip the same path even when they are harmless.

Edge cases

• Zipped attachments get scanned inside the zip, keep zips simple
• Very large files can time out the scan, split them
• A failing scanner service affects everyone, check with peers before panicking
