C:\WINDOWS\system32\dll.dll (Trojan.Downloader) -> No action taken. [3857535134305383807566791537808879778066697083130136276156424737485652618490848

I submitted the file to virustotal with nothing found.

I also ran dllcompare with no result.

Do you know what software this is part of ? What I am finding on google is almost never good but it does seem that thereare a few cases where it was not removed .

[JamesFrance]

No sorry I know nothing about this file.

Right clicking gives no info other than size of 2.5 Ko. It says created yesterday but that is because I decided to restore it and that it is an application extension.

It also suggests to open with Context Menu but that fails if I try. When it was quarantined I did not notice any problems but did not run much.

I did find this but don't know much about the site;

I decided to upload the file to ThreatExpert but the report wasn't much help to me:

I then copied the MD5 into Google and found this:

At the bottom of the report I found Comodo, so I am happy with that as I use their programs.

I went ahead and fixed this , let me know if the problem is resolved on your end .

[JamesFrance]

Yes thankyou, a new scan found nothing.

For Information, that file is part of the Comodo leaktest suite and harmless, it should have removed it when it was closed, but it was from an earlier version and somehow got left behind after running a test. Running the current version has now removed it from my system32.

Thanks for your help,
