Hi, I have a Lenovo G560 with Windows 7 Home Premium 64-bit OS, 4 GB (3.8 GB usable) RAM, 254 GB in the C Drive and about 28.9 GB in the D Drive. I have owned and used this laptop continuously since October 2010.
My computer has been very slow recently. When I boot it up, it will be fine and work normally. After using it for an hour, maybe longer, my computer will suddenly lag and come to a point where I can't open up a program or anything. Websites won't load and task manager, sticky notes, and the start menu (just to name a few) won't open. Even when I try to shut down the computer (opposed to pressing the button to shut it off) using the start menu, it takes more than 15 minutes, and sometimes I still need to press the button. This started around the time I downloaded offline Minecraft, but I doubt it has anything to do with that, since my other friends don't have any problems, and we all downloaded it from the same source.
After the first laggy episode, which happened 5 days after downloading Minecraft, I updated my Ad-Aware to the latest version. The version before did not include the anti-virus program it has now, but I do not remember the exact name or version number. I ran a full scan with this new Ad-Aware and it did not find anything. I also run a daily scan with Avast! and it has not found anything, yet. I have run numerous scans with both of these programs. I also try to close any processes that I'm not using, via task manager.
I'm afraid that I might have some sort of spyware that causes my computer to lag, but my computer is not slow all the time. Up until a few weeks ago, when I downloaded Minecraft, my computer ran as fast as it did since I first got it.
