CA Anti-Spyware Scan of J on 2008-09-15

A user of a Windows XP Professional Service Pack 3 system, J, reported that sometimes the taskbar disappears and the system is still freezing occasionally. I checked the system on September 15, 2008 with RUBotted. It reported "no bots found." Windows Defender, which is free antispyware software from Microsoft, is configured on the system to run every day at about 2:00 in the morning. I checked its results for today. It reported "No unwanted or harmful software detected. You computer is running normally."

I downloaded and isntalled CA Anti-Spyware 2008 LE. The Free CA Anti-Spyware 2008 LE trial only detects spyware threats; it does not remove them. To remove threats, full version activation is required. CA Anti-Spyware 2008 currently costs $39.99 for a 3-user download. Alterntatively you can buy CA's Internet Security Suite, which contains the anti-spyware software for $49.99.

On September 16, I performed a Google search. I noticed that, when I clicked on links provided by Google, the first time I clicked on the links they did not take me to the relevant webpage, but would take me to another page. The system was running Internet Explorer 6. I upgraded it to Internet Explorer 7, but after the upgrade saw the same behavior.
