I've lurked on these boards periodically, and I've decided to register because my computer's become much more awkward recently. I just realized that I've been using CCleaner, with the prefetch data box checked. I've done dozens of scans like this, and am curious if it'll have a negative effect. Sometimes, the internet will sporadically pause and stop. Also, this is the first time I've seen this occur, but my letters are skipping, and bits of my sentence are skipping back. I'm currently following step 1, of the preliminary instructions to clean my computer, and am typing with the Trend Micro HouseCall 6.5 running in the background. My typing is fine, the computer is just randomly rearranging areas of my sentence. I've had to backspace multiple times throughout this post to not seem illiterate. Un-edited text example: Alwork and no play maks Jack a dull boy.ce l That was keyed perfectly, and it's coming out awkward. I hope it's just a random effect for typing and running Trend Micro's anti-virus software. I'll re-post back after this scan finishes with a HJT log, etc.
