Hi Polonus,

Thank you for your advice!
After I have made a scan of “template.php” file, (results in the attachment), avast! shows every now and then the pop up window, which informs that it has blocked a threat (see the attachment). What do I have to do next? I’m afraid there is still a lot of work, and as I realize, the problem probably comes from the link, which have been attached to logo image of the company which the template came from. As I use several modules from the same company, it is likely to have the same problems with other templates, including joomla templates.

Thank you again!
