On my desktop machine running XP, whenever I try to enter data into an input field such as logging on or even typing an email the characters are not showing up. Even the cursor doesn't show up. Coincidentally, all of my restore points have disapeared, not even the calendar shows up and my McAfee security system will not load it's summary screen. Everything else seems to be working fine. It's mostly just the entry points. I did recently run Cleanup and I run ccleaner every day. Scanned with McAfee and found no viruses but can't log on to GTG from that machine. Help please.
