Kaspersky blocking acess to university website

[esdo]

Hello

I need to acess my university web page (www.prograd.ufpr.br) and kaspersky wont let me. Says site is not trustworthy. If I ignore the message and click access anyways, it accesses the site but saying that it is under maintenance. I know for a fact it is not under maintenance because I can access it normally via cellphone.

Things ive tried:

1. Adding a exclusion for said site;
2. Completely disabling kaspersky (this still gives me a kaspersky error message, i dont know how);
3. Using other web browsers;
4. Resetting PC and router.

None worked. The only solution is completely uninstalling kaspersky.

If im now able to solve this problem I will be forced to find alternative anti-virus software since accessing said university site is essential for my wokflow.

 

Thanks.
