This is how I discovered that I had a hidden pet in my laptop.
For many months I kept having problems with my internet connectivity. I would call PLDT dsl all the time to complain. This week a very capable pldt tech support guy came and check my connection, he used his laptop to connect to Http://www.speedtest.net his ping was 20 to 36ms and download speed 1.60 mbps. But on mine my ping was 560+ consistently but download speed was at 1.3 to 1.5 mbps. But was very unstable. I was ask to boot into safe mode, and low and behold my ping dropped to 20 to 30ms!!!
I tried everything to remove the Trojan/Virus but just couldn't figure it out. So I reformatted my drive and now everything is running so much faster.
