Well, lately I've been getting quite a lot of packetloss in everything I try to do (uploading, testing speed, playing games, ...).
Now, I'm wondering if I should blame my provider.. o.o. I've scanned my whole comp for Virusses and Spyware (using AVG and Ad-Aware), and my PC was completely junk-free.

Anyone know how I can get it down?

EDIt: I just scanned again and it found 3 virusses. It seems like the more I scan, the more virusses I get. What the hell?
If your loosing internet speed etc. It may be your ethernet card or the cable or modem you are using.

I had this problem ><
It's most likely your provider. I would call them up and complain.
