I ran a scan and had 3 pdf files show up positive with high threat in the results. I think this is a false positive because these files are statements from my credit union, and I had to get a special code in an email to even be able to download them about 6 months ago. I have also scanned several times since then, and they have never been positive. I also scanned using the Trend Housecall online and nothing came up. Does anybody know about this? Thanks.
