Blank Urls in Internet Explorer 7 Favorites

A colleague was asking me if I knew of a problem that he experienced after he setup his new computer. He was using the Internet Explorer 7 and witnessed that some of his favorites would apparently lose the url field after a while. The favorites were still there, the description was there but the url was gone and just a blank field remained.

I was a bit puzzled because I never heard about something like that before. After searching for several minutes I found a solution. The antivirus application Antivir is apparently causing the problem and there are several fixes for this issue. The first fix is to download a patch from Microsoft
which apparently fixes the issue.

A second solution would be to download a fix provided by the developers of Antivir which switches the filters in Antivir to avoid the problem that urls are removed in Internet Explorer in the future. I hope I was able to help other users who have the same problems and don’t know what is causing it.
