The 83.149.75.33 Trojan.Vundo Browser Hijack Virus infected my computer with avast! running the entire time. I was downloading a file from the Interwebs and avast! started freaking out and my browsers started opening randomly and loading random web pages including http://83.149.75.33… So avast! was detecting the Trojan.Vundo running on my machine - yet by that time it was far too late…
So I just wanted people to be aware of this. I used this guy’s tutorial to remove it and it worked - basically used Malwarebytes’ Anti-Malware and it removed the infection on reboot. I like avast!, yet it sucks that it didnt protect me from the Trojan.Vundo.
what do you mean? If avast was sending you messages (assuming this is what you meant by “freaking out”) that something was wrong then it did do to some extent its job, didn’t it?
What exactly were the alerts avast gave?
Also, congratulations on successfully removing the malware. As a rule of thumb it’s always good to have a second or even third antispyware software (these are used as on demand scanners which help increase the likelihood of detecting a possible threats and removing them).
I use avast as well as Super Anti-Spyware (free version), Malwarebytes’ Anti-Malware (free edition) and Spyware Blaster (an immunization program). Avast will do a good job at catching most of the nasties out there but it’s not 100% full proof. No software is. I think the avast team will take note of this post and make any necessary changes.
I suggest you modify your post and change the URL http to hXXP to avoid accidental exposure to suspect sites, e.g. hXXp://83.149.75.33.
No one program is going to provide 100% protection, but in the five years I have been using avast I haven’t had a single infection, that is also attributable to exercising safe hex in what I do and where I venture.
I would also suggest a visit to this site, which scans your system for out of date programs that have patches to close vulnerabilities, http://secunia.com/software_inspector/. Since many malware variants get in through vulnerabilities in out of date software.
