First of all, here are my computer specs:
Operating system: Windows 7 ultimate
Motherboard: Asus M4A78t-E
Processor: Athlon x3 445
Videocard: Radeon 6770
Router: lynksys WRT54GC
Energy: 500W OCZ ModXStream
Randomly when i connect to hosts to play games in the internet (warcraft 3 and starcraft 2, for example) i get constant lag spikes every 5 seconds. When it begins and it is fine, it keeps fine until the end. If it isn't (about 50% chance) i get it all game long. I can only notice these things when i am either gaming or on skype, when i need a constant flow of data working without problems. I have no clue what could be causing this. I always used a wireless router but i never had these problems before with it, until two days ago. It becomes literally unplayable even with bandwitch usage in less than 5%.
I had run a full scan with avira and spybot S&D, nothing was found. But i still suspect this is the work of some malware, because my e-mail have been breached which was fixed by a brazillian program called bankerfix...
If anyone could possibly have the slightest clue about the matter, it is greatly appreciated. If you need any aditional info, please let me know.
