I know just enough about computers to be dangerous...
I have a Dell Latitude D830 laptop that my brother put together for me last Christmas. It recently occurred to me that I have no idea what AV he installed, or if it's just using what Windows comes with (which could be my problem right there).
I believe it's running on Windows 7, and I do let it do its updates on its own, daily, in the background.
The laptop has been sluggish and laggy as heck, and progressively getting worse over the past few months.. I haven't downloaded much of anything that I can recall, other than to save .jpg, .png and the occassional .gif to my external hard drive or desktop. I play a couple of pixel pet games, but not much else, and I visit a few forums and web comics. The lag is so bad that .gifs never play smoothly, and I've pretty much given up on watching any kind of youtube or vine videos. Sometimes I can get smooth audio, but the video is always herky jerky at best, and everything often just stops. Frequently, the audio and video aren't synced, the video lagging far behind the audio.
I use Firefox and have adblock plus on, it does a very good job most of the time. A few weeks ago, I visited Craigslist and that was where I first noticed the ads from 'getsavin'. I right clicked and blocked everything from Getsavin.com. I no longer saw the ads, but i would still have the line of text and sometimes a blank, white window- even on sites that are supposed to be completely ad free.
A friend advised me to look at the extensions on firefox and sure enough, there it was. I used the remove button and got rid of the ads. So that was one problem fixed.
However, the computer still runs extremely slowly, and it will randomly click when I haven't touched the mouse or touch pad.
To try to combat the slowness, I have run the Microsoft Security Essentials full scan, and it found nothing. I installed and ran Spybot S&D, and it found nothing. I have cleared temp files (a week or so ago, I forget now what method I used, advice for doing this again would be appreciated), and defragged. Nothing seems to help.
The bootup isn't too long, but webpages tend to load slowly, and if I'm multi-tasking, which I usually am, I may have a website window up, a few IM windows open and either MS Paint, Open Office word documents, or Solitaire up. Any of these may apparently randomly decide that it is "not responding", will often fade white, and sit there for a few seconds or minutes before continuing.
Additionally, the computer will randomly click where the arrow for the mouse is sitting, or will flip windows so that I'm looking at a different application than the one I'm trying to work on - this often happens while one is 'not responding'. Sometimes when it does this random clicking, it will also highlight things. It's not the mouse. I unplugged it (*cough* and threw it across the room...) only to discover the issue continuing. Sometimes it happens just once or twice an hour, and other times it's virtually impossible to type anything because it keeps clicking outside the dialog box, or back into the middle of my sentence or won't actually click into the dialog box so I can type anything.
Of course, it's not doing any of this right now, but yesterday morning it was so bad with clicking elsewhere and highlighting things that I had to force a reboot (held the power button until it shut down)
With the lagging... I type, on average, probably 50wpm, often less, as I pause to think, but sometimes upwards of 80wpm if I'm on a roll. Frequently - and even as I'm typing here, I have to wait for the computer to catch up to me. This is no good for an aspiring novelist!
After asking for some help from one of the forums I frequent, I got rid of the ads - as far as I know. And, I was pointed over here for further help. Based on another thread where someone was having ad problems, I have now installed and run Malware Bytes. It found nothing, but I kept the log.
I have installed and run TDSSkiller. It found nothing, and again, I kept the log.
And finally, I installed and ran ESET. It found two things, but the log means jack diddly to me, so I haven't removed anything, but I did keep the log
So, I can post those logs if asked to, or I'm willing to install, scan, post logs whatever of what ever else may help.
Thank you in advance.
