So this is what's been happening starting yesterday. I left my computer on with Gmail on firefox and went downstairs to clean transformers. When I came up about 2 hours later, I noticed that my computer was significantly slower. The mouse response, minimizing windows, opening start ups, etc. It slowed to the point of a crawl. Then I noticed that my internet connection is constantly sending and receiving- way more bandwidth then it should be on gmail. I closed firefox, and it is still sending a ton of packings and receiving as well. So I restarted the computer and ran Malware antivirus, couldn't find anything. I ran spybot, and it stopped in the middle because whatever is clogging my computer is killing the resource and spybot couldn't finish the full scan before freezing or slowing to a crawl. I restarted the computer again, and this time unplugged my internet cable from the computer (I downloaded the latest update for spybot before then) and ran spybot. It came out with a few things like palevo, and supposely they are fixed. I plug back in the internet cable, and for a few minutes it seems fine. When I don't have browser opened, there is minimum packets sending back and forth. When I open browser, ofcourse there are packets. I think I browsed TFW2005 for a little bit as well as gmail before it started to act up again. If I restart the computer, I can get it to run normally for a short period of time, and then it does a drastic slow down, and shows my internet connection sending WAYYYY too much packets back and forth from web browsing. The virus scans don't find anything, and spybot found some and removed already. What else can be done? Is there any program to catch this? This happened yesterday, and I am sure it is not the hardware of my computer. Let me know what you think and what can be helped. Right now I am at work so work comp is obviously fine.
