If I load, at startup, McAfee's Vshield, all is initially well. But as time goes on the CPU usage climbs and climbs until the mouse gets jerky, everything slows down, etc. and disk i/o skyrockets along with CPU usage. 4 or 5 hours of routine use (surfing, e-mail, word processing, nothing special) is all it takes. I can remove all visible running codes and the CPU usage stays high. (I "see" CPU usage via MemTurbo). ReBoot and it starts over. This either started, or got noticeably worse, last week with an upgrade of the "engine" to 4.1.50. If Vshield is not loaded, then all is smooth all day long.
Anybody else see this? Curable? (I feel a little naked running without the virus checking in place.)
