Avast Free 5.0.594
Windows XP Pro SP-3
I get a popup from Avast telling me, for example, a linked image in a web page is infected. This was in a forum where the user linked to a photo showing some config data. Avast pops up its alert window telling me the pest is "JS:Script-inf[Trj]". Okay, I figure "[Trj]" means "Trojan" and that it is about some Javascript in the image. I can guess but I'd rather go read Avast's definition of the title they gave to this pest.
Clicking the "More Information" link in the alert window is worse than useless. It is adware trying to convince me to buy a payware version (to get the sandbox feature). I actually wanted more information - but on the pest to which Avast alerted. I don't need to see their advertisement page.
After hunting around their web site for nearly 20 minutes, I gave up trying to find a sub-site that lists their malware and gives definitions to them (which describes the pest, how it behaves, and perhaps even the manual steps to eradicate the pest). Telling the user they were protect from some pest which is given no definition is typical of rogueware (where you visit a site and suddenly it appears a scan is being performed on your host and falsely reports you are infected to lure you into buying their bogus AV software). Idiot lights on a car are for, well, idiots and I expect better from an anti-virus program where users should be allowed be be pro-active or even reactive to any alerts issued in their face about a suspected pest.
Where at Avast do users go to get more information about the *pest*, not some ad page to buy their payware version?
