I'm suddenly unable to update SuperAntiSpyware or MalwareBytes Anti-Malware (the free editions of each). The last successful update of each was around the beginning of this month. Before that, I'd updated them regularly (about every two to three weeks) without any problems.
I run Windows XP (Media Centre) with SP3 and automatic updates. I connect to the internet via a Siemens Gigaset SE587 router, to which my PC is hard-wired. Other PC's in the house connect to the same box wirelessly. The router has a pre-installed firewall which I have never made any alterations to. I am currently able to surf the internet, so connectivity to the web doesn't appear to be an issue.
On my PC, I use the Windows firewall, and have always had it set up with SuperAntiSpyware as an exception. (MalwareBytes is not on my exception list, but has always updated OK). I do not use any other firewall software. When trying to update SuperAntiSpyware, using the "Check For Updates" button produces the following message -
"There was an error trying to retrieve definitions. Make sure your firewall is not blocking SUPERANTISPYWARE.EXE from accessing the internet"With MalwareBytes, I get -
"An error occurred. Please report the error code to the MalwareBytes Anti-Malware support team, Error Code 732 (2, 0), The system cannot find the file specified"
I ran scans with both today, and removed three items found - SuperAntiSpyware found a Broken File Association (which it does every time I run it), while MalwareBytes found two registry entries associated with backdoor.bot.
The only other hint I've had in recently that things are not quite as they should be is an occasional redirect when clicking on a link brought up by a Google search, but this has been an intermittent glitch that has been around for several weeks. I haven't noticed anything else that might indicate a problem.
I did a little research on the update issue, and found several very similar threads across a number of forums. In each case, there were differences to my situation - people using third party firewalls, or running Vista, for example - so I thought it best to start a new thread here.
