My PC's got malware

Postby Ian Pegler » Tue Feb 10, 2009 8:16 am

Sorry I haven't been doing much on the forum of late.

This is because my computer has a virus of the kind termed "malware".

Effectively my browser has been hijacked. The symptoms become apparent
when I try to use Google either using IE or Firefox. What happens is I type in
keywords into Google, I get a list of sites back, but the links are to irrelevant
sites.

This sounds like a minor thing but it isn't - believe me. These things can leave a
door open for other, more harmful viruses to attack you.

I have tried numerous anti-virus applications so far, including:

McAfee
SpyBot
Lavasoft's Adaware
Spyware doctor
SuperAntispyware
Malwarebyte's Anti Malware
An online virus scan called ESET

None of which worked. I have tried clearing out my
cache, history, cookies etc. all to no avail.

Any suggestions gratefully received...

Sympathies.

Maybe install free AVG (I actually pay for the upgrade cos it seems to do the business better than most);
(available from here)
zap IE (always a good thing to do!!!) and also Firefox; and reinstall Firefox first? Check the system again. Reinstall IE. As you have already gone thro' cache & cookies you have nothing else to lose!

Sorry to hear you're having trouble, Ian. I don't know if us lot are the best advisers on the subject, but you never know! I can't really add any recommendations to what you've done, apart from uninstalling and reinstalling Firefox maybe? Or try Google Chromebrowser perhaps?

There is a lot of it going about at the moment. We seem to be getting a lot of spammer registrations on the forum at the moment too. I've had over three dozen bounced registration emails in the last few days. They haven't been approved however, so we're still safe for the moment.

Try the McAfee Stinger available off the McAfee web site. We used to use this when I worked for BT and it is a very effective malware and trojan remover , then run CCleaner off the piriform web site to clear up any remaining files etc. Both have proved effective for me in the past and better still both are free.

I noticed that when I did a Google search the Status bar said "Waiting for 7.7.7.0"

I did a search and found several pages about this including.

This was the breakthough moment.

I have removed the offending file manually and now Google is back to normal at least.

Getting there...

I have discovered that the malware is distributed by Javascript attached to a PDF file. To prevent this kind of thing happening I have installed an opensource Addon called NoScript which by default blocks scripts from executing unless and until you decide to trust the site. Seems to work.

Other preventative measures (as suggested by this site where you will also find a tool for detecting this malware):

Adober Reader: Disable Adobe JavaScript functionality (Edit -> Preferences, go to JavaScript entry and untick “Enable Acrobat JavaScript”)

Foxit Reader: Edit -> Preferences -> JavaScript (Uncheck the box)

Really useful posts & links Ian- thanks. Or rather, come to think of it, I hope they will not be of use! :roll:

Thanks Simon

As an aside I recently tried out a piece of anti-virus software called AVAST which detected a "root-kit" called Daonol-G. Hopefully my PC is on the road to recovery though.
