... who is Jotti?
Hi Alex,
Jotti is an on-line service that scans a file you submit with many antivirus programs. This gives you multiple opinions about whether the file is infected or not. It is located here:
http://virusscan.jotti.org/The problem is you need to locate the file on your computer in order to use Jotti.
IF Avast says I do not have a virus, why does Trend Micro say I have one 
?
Different antivirus programs use different detection techniques and different virus signatures. This often leads to disagreement as to what is and is not malware.
I delete it and do another scan and it's gone the next scan.
The next days I do another scan and it's back.
If you follow Polonus' first link above there is a "Solution" link toward the bottom of the page. Click on that and see if the information is something you can work with. When you do the Trend Micro suggested there (yes you will need to do it again) make sure to notate the file name and location (it will look something like C:\windows\filename.ext).
Post again with the file name and path and/or if you need additional help.
