Avast v. AVG

  pienter 21:09 07 Nov 2008

I have recently switched from AVG to Avast and find that the latter reports a large number of files which it is unable to scan because they are either decompression bombs or are password protected. The bombs are VOB files and many of the password protected files belong to SpyBot, both sources which I recognise. Some of the password protected items are, however, files identified by large alpha numeric titles. How can one discover if these are dangerous? Also why does AVG not report any of these problems? Is Avast more thorough than AVG?

The "files identified by large alpha numeric titles" are probably files to do with either your operating system or they are Windows Updates.

"Is Avast more thorough than AVG"

Some will say Avast is and Vice versa. Personally I use neither, I have used Avira for around 4 months and find it excellent, very light on your system resources. From what I could gather Avira tends to score higher on detection than Avast or AVG.

I used AVG for a very short while on one XP laptop, I soon Put Free Avast on it, like my other XP computers

I prefer Avast to AVG. In my opinion it does a more thorough job. I'm always open to change, though, so FatboySlim71, how about a link to Avira, so we can at least look at it.

Avast is reporting these things nd AVG is not, probably because the free version of AVG isn't checking them, and/or because you've not set an option to check them.

There are many things the free version of AVG doesn't do - see here.

I't quite correct that if the Spybot deleted item folder is checked, the files are compressed and password protected - that's to insulate potentially harmful files from being activated. So Avast is correct.

The same will be true for any password protected files - they cannot be checked because the AV scan cannot open them (correctly.)

Read here about "decompression bombs"

Sounds like a flaw in the method used to check inside large compressed files to me.

Avira free version also suffers from lack of facilities, just like AVG

however what it does have seems a tad better than AVG free (Avira has some Rootkit protection for instance)

You just can't beat a good comprehensive AV program - you just have to pay to get one.
