Why was my computer infected by the Security Tools malware while camwin is running?

ClamWin is not a resident/real-time scanner, as explained on the ClamWin home page. It is an on-demand scanner that scans only when you want it to scan--either manually or via a scheduled scan. A resident or real-time scanner scans files as they are accessed/placed on your computer. If you surf the web a lot, you should rely upon a real-time scanner with ClamWin as a backup.

If ClamWin is your only scanner, you could get an infection and not know about it until you do a scan with ClamWin. In addition, ClamWin must have a signature for each virus in its signature database, so if it does not have a signature for a particular virus, it will not be able to spot it, even during a scan.

There are several free real-time scanners that are very good. If you need one, look into Microsoft's Security Essentials, Alwil's Avast, and Avira's AntiVir. Another option is to use the ClamSentinel program, which adds a real-time scanning capability to ClamWin and, in addition, it provides heuristic detection/quarantine for unknown viruses and warns you when there is a suspicious file placed on your computer. The ClamSentinel site is at https://sourceforge.net/projects/clamsentinel/ on the web. ClamWin should be installed before you install Clam Sentinel.

Keep in mind that no antivirus is a substitute for common sense and safe surfing practices.

Bye bye clamwin, I don't see the purpose of running something that does not protect you. I loaded MSE and found 2 backdoor viruses and about 20 infected files. Wow what an eye opener, here I thought clamwin was actually protecting me.

ClamWin detects/quarantines/removes viruses when it finds them during an on-demand scan. Some people prefer to use an on-demand scanner instead of a real-time scanner. These people want an uncomplicated antivirus program that does not use too many of their computer resources. These people also are careful about where they surf and what they click on.

Thank you for trying ClamWin. I suggest that you read/learn about a software program before you jump in and install it. Also, keep in mind that no AV program is a substitute for common sense and good surfing habits.
