My internet has gone really slow lately, is it because of [DoS] Attacks.?

I have been getting slow internet, I looked into my router settings and found this in Security Logs:

There are more but I will run out of characters.

Is there anything I can do to prevent this:

Virginmedia 10MB/s connection.

Please help, do I have a virus, how can I troubleshoot?

easily a small team of human beings can gain this. Why? via fact they are in a position to and get their jollies from screwing human beings up. it works like this. shall we take objective (AOL internet messenger). final 3 hundred and sixty 5 days a malicious software pipeline.W32 became into pointed out which used a loophole and time-honored itself on machines. It became into curiously organising an extremely state-of-the-paintings bot internet. It allowed specific ips to take over administration of the contaminated laptop and use it for its very own purposes. probably DOS assaults. The administration ip can take administration and use all the contaminated computers to concurrently link to the objective web site. this is the time-honored approach of the form of ingredient. it would, theoretically in basic terms take one guy or woman to start it.

Yes... seems like Denial of Service. Run a virus scan.If it doesn't pick up on anything, run another virus scan by installing a different one (and installing the original virus scan). Eventully a viru scan will pick it up
