So two days ago, my former boss called and asked if I could take a look at her computer. She complained that is was moving really slowly, and I agreed because they were really good to me there. I got the computer and figured that it was just the typical maintenance that needed to be done.
First, I ran the aggressive scan disk, which took about 30 minutes. It did not find anything that really concerned me. Next I ran the disk clean up tool, which took about an hour. The real reason for this is that I allowed it to compress old files. That ended up saving me nearly a gig of disk space, which was nice. Finally I ran the disk defragmenter utility, even though it said it did not really need it. About 40 minutes later I was playing with it and it seemed to be loading up programs a a pretty good clip for a two year old laptop.
I decided that since she was a novice computer user I should also run the Anti-Spyware and Anti-Virus software I installed when she got the computer. First I ran Ad-Aware, it failed to get any updates for it, but I did not think much about that because it failed the last time I ran on my computer as well. I ran a full scan of the computer , and the only thing that it found was tracking cookies. Not a big deal I thought, but I went ahead and deleted them just to be sure.
I also had Spy-Bot Search & Destroy installed on the computer, so I decided to run it as well as they tend to find different items installed on a computer. I ran the updater for this, but it took forever and failed to download anything. Now this concerned me because this has never happened to me before. I launched IE, and her home page failed to load. I grabbed my other laptop to be sure it was not a connection issue with my network, but that one connected just fine to the net. That was pretty weird, so I went to an online anti-virus/anti-spyware scanner, and it found 5 items that were definitely more than just tracking cookies.
I told the scanner to delete the items, and it recommended that I scan again so I did. An hour later it came back with one item. This kind of made me mad because it was one of the ones I told it to delete before.
I deleted it again, rebooted the computer and now was able to connect to the Internet at a decent clip. I downloaded the updates for Spy-Bot and it found remnants of the spyware that I just deleted. I hope that it is gone now, but told my former boss that if it happens again we will need to back up her important files and rebuild the computer from scratch.
I have a feeling that it will come back again. When it does I will recommend that the first thing we do is to install a better anti-spyware program, such as Spy Sweeper to prevent this from happening again. I don't mind doing regular maintenance on a computer, but once you have Spyware you can never be sure it is truly gone without doing a full rebuild of the computer.
