Repeated blocked attacks

Hello. I already posted this issue before, but it hasn't been resolved.

 

Recently NIS has been blocking attacks on a daily basis. Here's the descriptions.

 

Web Attack: Malicious Exploit Kit Website 4

 

Web Attack: Suspicious Browser Fingerprinting 3.

 

What's curious is the blocked attacks come in a specific pattern. They only happen in the morning. They never happen any other time of the day. Secondly, they appear to happen only on my user profile.

 

Is this the sign of a virus and if so, what should I do?
