My scan today showed 6 Excel files were infected by "Excel Exploit"...this seems to be spread by email attachments. Surprising, since none of the infected files were received via email, and I had not even used them recently. Also, I use hotmail for email, which supposedly scans all attachments.

I sent the files to quarantine, updated AVG again, reran the scan which came back clean.

Anyone else experience this? Is there anything else I should be doing?

Thanks

I suspect that you are concerned about AVG's detections being possible false positives.

Since you updated AVG, you might try restoring the files from quarantine and then rescanning with the updated AVG. If the files still appear to be contaminated, you can always retest the restored files with other anti-malware programs, like those mentioned here:

From: http://forum.grisoft.cz/freeforum/read.php?4,90494,backpage=2,sv=

At this time we expect them to be false positives... for now leave them in the vault and when Grisoft corrects their definitions you can restore them....

If you suspect a file to be a false positive. Test the file at virusscan.jotti.org and if it is a false positive, archive (zip, arc, tar etc) the file using a password and email a copy to virus@grisoft.com with a brief description as well as the password you used to archive it with.

If it is a false positive , turn off hueristic scanning for the time being. When Grisoft adjusts the virus defintions you can turn it back on. You may have to disable the Resident Shield for this if turning off hueristics doesn't help.

Note: There will be an update out shortly today (AVI 268.17.36/ 681) Restore your Excel findings and re-scan with this new update.

Thanks for the info, guys.

I should have thought to check the AVG forum!
