1) My browser (Firefox 3.6.3) occasionally opens pop ups that will, if left alone, redirect to google.com/webhp
I've only allowed it to do this a few times (I usually close the tab as soon as it opens), but the one time when I didn't notice and typed something into that site, clicking a search result did redirect me to a page similar to those in the popups.
2) One of the svchost.exe processes on my computer often reaches very high levels of cpu consumption (95%+) and freezes everything else. I've been keeping it at bay by selectively killing threads with high cpu consumption with Process Explorer, but lately it sometimes freezes Process Explorer as well, forcing me to turn off the power. The services that this svchost.exe hosts are:
COM+ Event System [EventSystem], CryptSvc [CryptSvc], DHCP Client {Dhcp], Distributed Link Tracking Client [TrkWks], Help and Support [helpsvc], HID Input Service [HidServ], Network Connections [Netman], Network Location Awareness (NLA) [Nla], Secondary Logon [seclogon], Security Center [wscsvc], Server [lanmanserver], Shell Hardware Detection [ShellHWDetection], System Event Notification [SENS], System Restore Service [srservice], Task Scheduler [Schedule], Themes [Themes], Windows Audio [AudioSrv], Windows Firewall/Internet Connection Sharing (ICS) [SharedAccess], Windows Management Instrumentation [winmgmt], Windows Time [W32Time], Workstation [lanmanworkstation].
EDIT: Also causes the taskbar and start menu to become unresponsive, lagging everything else as well. "Solved" by killing explorer.exe, but when I tried to reopen it through task manager, task manager became unresponsive.
EDIT 2: Problem described in the previous edit occurred due to lack of memory (I only have 512mb, 446 in reality), and it became ok after I closed firefox. However, the svchost.exe in question is taking up 267mb of my memory, which is more than any of my svchost.exe used to.
EDIT 3: The same problem happened again shortly after, but closing firefox didn't help it. When I finally struggled through the lag and killed the svchost.exe, everything went back to normal. However, doing that often reverts my interface into an old style reminiscent of windows 98/95.
