Clamwin Anti-virus Review

Clamwin

This Anti-Virus has a very small foot print. From what I can tell, it has no real-time protection from virus' that might find their way onto your computer through the network or through web browsing. Certainly, it doesn't work for files that you download and install through your web browser. There is an option when you install it that has plug-ins for Internet Explorer and Outlook. I've seen it stop virus' in outlook, but it didn't stop it from coming, the pop up alert and virus prevention was from an email that the person had already downloaded via email and was attempting to forward it to me for examination because it looked suspicious. Installing this anti-virus requires a lot of work for admins. I installed it to run every day and notify me of virus' via email. That works fine, but there are so many false positives that I don't trust it to clean the virus, so I have to review the messages (which now come in from all of my PCs) and determine if the threat is real. Even when submitting a false positive, they free support team doesn't always remove or repair the issue. I am still getting false positive alerts from a chrome.dll that indicated the virus, but has since been replaced by a newer version from chrome, but now the alerts are coming from the very same file that's stored in system restore.

There are several add-ons to this software by other well-meaning public domain who attempt to close the gaps in Clamwin. One of these gaps is that Clamwin is not recognized by Windows. This isn't really an issue, but becomes one when the antivirus is out of date. No alert from windows lets the user know there is an issue. You do get a pop-up from Clamwin itself. All updates to this software requires manual installation and sometime a reboot. Most of my users won't do any updates because they don't know what to trust.

On the plus side, it's free, it has a small memory foot print, it rarely interferes with the normal course of business (this later item is the reason I wanted to try it),

I had a client installation that was sending me emails on a virus it found it the FixTDSS quarantine everyday. Really annoying, right? Problem was there was a rootkit, a javascript virus in the Google chrome path and a virus in the Adobe downloader that never got reported. The adobe downloader virus took forever to find, AVG couldn't find it either and the ESET online virus scanner couldn't find it. To really drill down the Clamwin team is going to need to have the signature transmitted to them automatically just like all the other free scanners do, so they can investigate the reported problems and better identify the false positives.

Windows XP Programs Run but don't show on the Desktop

Posted at 3:32:40 PM in Recovery (44)

This computer had several bugs and virus issues, but the problem wasn't a virus. The symptoms were a blank desktop no mouse but the task bar displayed with the start button and the start button would respond to keyboard commands, but all the programs that showed on the task bar did not show up on the screen.  Therefore, screen properties (which doesn't show an icon on the task bar) wouldn't appear in the viewable area in order to make or view any changes. Safe mode worked fine however. All the icons and all the programs worked fine in safe mode. Resetting the video in safe mode did not help. In fact, Safe mode didn't show the actual configuration of the video settings that were employed in real mode.

I scanned for virus' in safe mode and found several and removed them, but this didn't fix the problem. What I noticed was that the mouse would disappear off the left side of the screen and when moving it back to the right again, it would take some time before it appear. This indicated to me that there was additional desktop real estate that I couldn't see. To test this, there was a program that was running on every boot where I used msconfig to disable everything that wasn't windows. I couldn't see the message on that window. I assumed it was behind an active desktop virus that was hiding it. So I tried moving it. It runs in a window by default, so I just pressed Alt-Space and then M(ove) and used the arrow keys to move the window to the right. The window area showed up and every time I selected an option, it'd snap right back to the left. The options worked, the dialog boxes requesting the next step, such as reboot now, popped back to the center of the screen off to the left. Obviously, the screen was in dual monitor mode and the screen I was looking at was not the primary monitor, though I am puzzled about why the taskbar and start button showed up on the single monitor I was using.

The move command as I used it here worked on the properties window for the desktop and I was able to move it into the visible area. On the settings tab, there were to monitors and they were extended. I just needed to select the monitor where I could turn off the extending function and then select the monitor I had plugged in as the primary monitor and the problem was fixed.

logmein and Windows 7 remote desktop fails

Posted at 10:02:31 AM in Recovery (44)

Brand new laptop right out of the box with Windows 7 Home Premium and we cannot connect to the remote PC. The message is connection refused in Chrome and IE 9 shows no information without expanding the details link. However, under that link, there is a message that states if your using an HTTPS connection, check out the security section in Internet options under the Advanced tab. 

Apparently, IE 9 new installs only have TLS 1.0 enabled and SSL 2.0 and 3.0. I don't know which is required for logmein to work, so I enabled all of them. So, SSL 1.0, and TLS 1.1. and TLS 1.2. We are now able to connect to the remote desktop.
