Please remember to backup your files!
Another “malware” (spyware, adware, etc) infection this week. My friend had a really bad situation. His Windows 98 machine was infected with 113 malware programs. As soon as a clean-up was finished, I would relaunch Adaware and they were all back!
I then tried to update his virus software’s definitions so that I could run a virus scan. It turns out the virus software was an older OEM version which update availability had expired. So I found a good free (and up-to-date) virus scanner, installed it, and booted into safe mode (holding ctrl while booting). Then ran a full virus scan and 54 viruses and trojans were discovered! The virus scanner got most of them but had trouble removing a few.
So then I looked those specific ones up through Google, and found a free tool from Trend. I ran that and it seemed to do the trick cleaning off the stragglers.
Now, to prevent future occurrences…
I set the virus scanner up to protect the system and get frequent updates automatically.
Then installed a free personal firewall, and configured to allow the common applications (web, mail, streaming video).
Then I made sure all of the windows critical updates were completed (especially the IE patches).
Then I enabled all protection through Spywareblaster (which modifies browser settings) so that the common hooks that spyware authors use were disabled.
The machine is all healthy now! I was thinking that it was a good ting the viruses and Trojans were “only” installing spyware and not deleting files and other malicious things. Please remember to backup your files!
