AVG virus software (free version)

[wpshooter]

Have a friend that has a virus infected computer.

He tells me that the virus is preventing him from getting to the Internet.

If I download (from my computer) and install (on his computer) the free version of AVG anti-virus software to use to scan his computer for viruses, will it have the most up-to-date virus defintions when I do the installation or will the definitions need to be brought up-to-date in order to assure that it will do a complete job of scanning for viruses or will I ALSO need to download (from my computer) the latest definitions to use to update the definitions once the program has been installed on his computer. I see a listing for the 07-12-2011 definitions on the AVG website. Does the AVG program allow for me to browse for/to this definition file which I would place on his hard drive, instead of trying to retrieve the definitions from the AVG website, which he can not for right now get to ?

Thanks.

AVG is bloated, and a good bit of malware seems to slip right through its fingers, when even MSSE will catch them. Antivir and Avast are good; and even MSSE isn't half bad, but it is a focus-stealing bastard, and Windows' window manager kinda sucks (not a good choice for gamers).

Find out more about what it is. If it is a rogue scareware, now the most common things that do that, get rkill (just get all the names) and MBAM, and you'll have a >95% chance of getting rid of it. Run rkill variants until one actually works, then once it's done, install and run MBAM.

If it is only keeping web access down, Hijackthis could be enough, though you still might want rkill. With HJT, you're mainly looking for odd proxies, and highly suspicious BHOs (browser helper objects).

If you don't know more, at the least, get all three of the above (more like 8-9, by the time you have all the rkills), and maybe add an AV client that isn't AVG.

Otherwise, remove the HDD, and in another computer, scan it with MBAM (and the other computer's own drive(s), in case it spreads automatically), then that computer's AV client.
