I ran my scans today (after getting my MS updates) Avast full, Mbam Quick scan & Superantispyware quick scan & as usual they came up clean. I then rebooted & got a flickering screen with boot sector options & other choices one of which was F4 to exit. Not being a techie, I tapped F4 & it continued its reboot process. This is the 2nd time this has happened with the new version of Superantispyware. After it rebooted, I got another MS update & had to restart again & got that flickering screen. I'm unable to get a screen shot of it & no camera to take a picture of it. This first happened just after Superantispyware updated to its current version. XP MCE 512 mb RAM. Need more info? I'll try to answer them.
