Hi All! I have this exact problem & it just showed up after an update but don't remember exact one. It starts when I right click & try to start a scan. It scans the memory, & states that it will now continue then nothing happens & I'm left with this strange blue rectangle thing that is what ever you have clicked on last. Like copy, start avast, cut whatever I restart, then it goes away until the next time I want to start it. I just updated my graphics driver last nite, still happening, went into control panel, ad/remove & did a repair on avast & it worked wonderful for a couple of times, then boom here it came again. I also uninstalled my firewall, then tried again, still got the rectangle leftover, then I uninstalled win patrol, still didn't work so don't know what else to do. I have pentium 4, XPhome, 2.80 GHz, 512 MB Ram 2.79 GHz I also have Kerio Firewall, The avast home newest program offered, Spysweeper, Sp2 all updates are in, Win Patrol
I really think it has something to do with Avast but sure don't have an answer yet. I've never had a problem until just here lately. Hope someone has some answers.
