Hi. I found this place while searching Google concerning the constant attacks on my computer. You seem to be the best source of advice so here's hoping you can help.
A few weeks ago my computer was infected by the dengwvytssd.exe trojan, which got through Norton Internet Security's defences and threw up lots of fake warning messages. When I ran a Norton quick scan it found and quarantined the virus so I haven't been experiencing any more of those messages. However, Norton has been picking up and blocking regular intrusion attempts labelled "HTTP Tidserv Request" or "HTTPS Tidserv Request 2". These seem to come in two forms:
a) Attacks from 01n02n4cx00.cc and others on a 'clockface' basis - a new attempt every 30 minutes;
Attacks from 18.104.22.168 (and others?) when I open up Google (although not every time).
I recently ran Malwarebytes' Anti-Malware program, which found and removed a few trojan and rogue anti-virus things, but the attacks keep coming.
So to start with my questions are:
1) If Norton is detecting and blocking these attempts, do I have anything to worry about?
2) What are these people hoping to achieve by repeated attacks on a 'protected' machine?
3) Presumably something has been left behind that notices when I go to google.co.uk - can I get rid of it?
Grateful for any advice.
