I'm running an XP machine and in the last two days I've noticed network connectivity to be very slow on the computer. After a reboot, it is fine. I suspected a virus so I ran a full Symantec scan (not sure how the computer got a virus, since Symantec was enabled the whole time). It found two viruses/worms (I don't have the computer with me right so, so I don't recall the names). I deleted the infected files and then ran a Spybot scan -- it also found a couple of things which I removed.
At this point, all scans come back negative but it is still causing me hell -- websites redirect to adware sites, network is slow, etc. I tried to reboot into safe mode and run another scan, but when I try to enter safe mode the computer reboots.
I searched the net for "removal" tools for both of these viruses, but there didn't seem to be any. Symantec's website just recommended a full scan of the computer to remove the virus.
Any suggestions would be appreciated.
