I've been recently having some strange computer problems.  My Task Manager was all kinds of goofy.  It would continually spike to between 95% and 100% usage even though I wasn't really doing anything with my computer. I also had some Chinese characters that would display in the address bar on occasion.  I searched all over the Internet looking for a solution but was never really able to find anything concrete.  I also constantly had at least one msiexec.exe running and at times there were many of them running.  The would regularly pop up to the top of the CPU usage and I wasn't fast enough to be able to cancel them. I originally thought that it was a virus or spyway, etc. (and it could still be) but I noticed a strange trend that put me on a path to removing it from my computer (I hope) and maybe this will help others. I tried several virus and AdWare/SpyWare scanners but they never found anything, which was perplexing to say the least. I have an HP OfficeJet J6400 Series printer, which I bought several months ago after the death of my 5610xi.  I liked the 6400 series because it was network capable and it allowed me several options that the 5610 didn't. One strange thing that I found was that whenever the 6400 was turned on, the conditions I've described would be present, but when I turned it off, things were much better though they didn't go away completely. I hadn't used it for anything other than printing, but recently started using it more and more for scanning.  While doing all of the virus/spyware/adware scans on my desktop I needed to user the scanner on the printer so I installed the software on my laptop.  Everything worked great, until I went to use IE on my laptop.  Previously I did not have the problem with the Chinese characters in the address bar but after installing the HP Solution Center software it suddenly had the same problem as my desktop. This got me to thinking, because as I was trying to work with my desktop it was having problems with the HP Solution Center.  It wouldn't install properly (always throwing an error regarding the registration of flash9b.ocx) and sometimes it wouldn't even run at all. I continued poking around trying different things (this type of computer problem is not my forte).  In the end, what I ended up doing was completely uninstalling all HP printing/scanning software on my computer using the Uninstall utility that HP has on their site, then upgrading Flash to the latest version and reinstalling all of the HP software.  I also upgraded the Firmware on the 6400 series. It appears to have corrected the problem that I had at least for now.  I have no idea what was going on or if I've even correctly solved the problem, but if this can help anyone who may be having the same difficulties, then I'm happy.
