Hi,
I am the one who blocked your ip address because I saw hundreds of errors in my log caused from this ip address in rapid bursts of multiple requests per second. These errors caused no harm but were evidence of malicious intent or unauthorised penetration testing.
Your explanation that it was caused by a virus seems possible but unlikely, nevertheless, I have unblocked your ip address for now. If I see further evidence of malicious requests from this ip I will block it again permanently.
Joe
