This morning I tried to download Adwcleaner from Bleepingcomputer and it reports it as a virus.

 

I have downloaded many times before no problem, is this a false positive.

 

If it is a false positive how to i download it and stop avast blocking the download.

 

If it helps, here's what Threatexpert made of it https://www.diigo.com/item/image/47azw/2dbw

Yes....false detections by anti-virus programs for specialized fix tools are not uncommon.

Certain embedded files that are part of legitimate programs or specialized fix tools, may at times be detected by some anti-virus and anti-malware scanners as suspicious, a Risk Tool, Hacking Tool, Potentially Unwanted Program, a possible threat or even Malware (virus/trojan) when that is not the case. This occurs for a variety of reasons to include the tool's compiler, the files it uses, whether files are compressed or packed, what behavior (routines, scripts, etc) it performs, any registry strings it may contain and the type of security engine that was used during the scan. Other legitimate files which may be obfuscated, encrypted or password protected in order to conceal itself so they do not allow access for scanning but often trigger alerts by anti-virus software.

When flagged by an anti-virus or security scanner, it's because the program includes features, behavior or files that appear suspicious or which can potentially be used for malicious purposes. Compressed and packed files in particular are often flagged as suspicious by security software because they have difficulty reading what is inside them. These detections do not necessarily mean the file is malicious or a bad program. It means it has the potential for being misused by others or that it was simply detected as suspicious or a threat due to the security program's heuristic analysis engine which provides the ability to detect possible new variants of malware. Anti-virus scanners cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert you or even automatically remove them. In these cases the detection is a "false positive" and can be ignored.

If you're attempting to download the file, either have avast ignore the detection or temporarily disable it until you download and run the tool.

To temporarily disable avast!, right-click on the avast! icon in system tray (looks like this: avast.jpg but orange in color starting with v5). Select avast! shields control and there will be options to disable avast for 10 minutes, 1 hour, until the computer is restarted or permanently.

Thanks Bleepin Janitor I have downloaded Adwcleaner hundred's of times before with no problem, only today has the problem started.

 

I think that Bleepingcomputer should provide a MD5 checksum for all it's downloads.
