I’ve been ignoring my intrusion alert numbers even though it showed 3000+ sometimes until today that I caught a person changing my yahoo messenger status with his intrusion which the CIS detected but I stupidly allowed.
I traced his IP and found that his ISP is the same with mine.
My question is why do I have 3000+ intrusion attempts logged? well mostly by 2-5 different Ip addresses. One is particularly persistent.
Do I have to worry about these intrusion attempts? Wat can I do to protect my PC better and how can I know if somebody got into my PC?
Thanks
