Few days back I found some links for downloading some spyware and I thought to give them a try against my security appliances. I just wanted to see myself how different antispywarse behave against theses samples. Before I proceed I want to tell very clearly that these are not tests at all, there was no definite criteria set to compare different scanners. All I can say it is just my little play with these spywares and I am just sharing my experience with u and if anybody goes for that he can share it as well and of course the results can be quite different. I put following appliances on my Notebook on XP SP2. Real Time Scanners Antivir with highest heuristics Spyware doctor trial Spysweeper trial OA Armor trial Ewido beta 4 trial Windows Defender SnoopFree Arovax Shield AppDefend trial On-demand scanners Spybot Adaware SuperAntispyware free Updated all( version and signatures) and made a clean snapshot of my system. Excluded the option for cookies scanning from them( not all scan for these though). Then I went to some web pages and tried to download following spywares WinFixer 2006 SpyAxe UnSpyPC Some games and video Best work was done by SpySweeper( Web Shield component of it) it immediately blocked my access to download pages for WinFixer and some other when I clicked the link, very fast action and was the first one to respond. I was really surprised. Also Spyware Doctor ( Process Guard component of it) stopped some of them from downloading by clearing them immediately. Windows Defender did not gave any warning- just sleeping there. Ewido no warning as well that surprised me. BTW Antivir cried too much on WinFixer and SpyAxe and I was happy to see its rapid response. Ewido gave warning but once only however I can't say exactly as by mistake it was disabled and I noted it later and enabled it and it cried once. So don't know exactly how it behaved here. I disabled SpySweeper, Spyware Doctor, ignored the warning of Antivir and downloaded WinFixer, SpyAxe and UnSpyPC. Now I enabled all scanners again and tried to install them. Again SpySweeper and SpywareDoctor stopped me multiple times telling rightly about threat and SpywareDoctor's "process guard component" removed some after showing pop ups. Antivir was crying as well but on WinFixer and SpyAxe. SnoopFree gave me warning only once but I think this is pretty useless as it gives same warning for both legitimate and malwares, so there is no way to decide for u whether the software about which it is warning is malware or not. No data base in it. Arovax shield warned immediately when some components added to start up or BHO, however also this is not useful as u have to decide urself what is good and bad. BTW, windows defender just woke up once and told that there is one component added to windows start up that I happily accepted. I ignored all warnings and installed the three spywares ( though I guess not completely as Spyware doctor removed some components). and run a short scan by these "anti-anti-malware scanners" but did not opt to fix anything. About Online Armor I like it so much but I will say I realized that it is not so useful for an average user like me as it will treat all unknown processes and malware as same. AppDefend even worse as it will cry too much but same for malware and legitimate installations, so I disabled both during installation of these spywares. They are for advanced users only. I will prefer a HIPS that only cries on some potentially dangerous activity, not on all executions and I used in the past and liked the HIPS component of ZA Pro but again I will say OA may be better than this as it covers much more but it will be much useful if it has some data base of malware for real time protection. AppDefend is just too much for any average user. After this I ran Quick Scan by all scanners. Spyware Doctor apparently found maximum entries( but I am not expert as all scanners count differently and no way/ time for me to analyze all these, I just tool a look and it was the one who took out maximum registry entries-- and it is my experience even in the past). Spy sweeper was good as well and SuperAntispyware free edition also( best of free scanners). Adaware acceptable results. Spybot very poor and disappointing- my opinion about this is changed now. Ewido and WindowsDefender results were poor so I ran complete scan by them and the results remained poor. Bazooka it never brings out anything but I tolerate only as it scans in a second and BTW it showed one entry "Exploit perlink.biz" ( don't know what is this). I scanned only selected locations by Antivir and it found two signatures of WinFixer and one of SpywareAxe. I ran security checkup wizard by OA and the results were not so impressive. If found UnSpyMe in start up but missed WinFixer and SpyWareAxe in programme files. BTW, I was surprised to see one of these, probably UnSpyPC came bundled with Yahoo toolbar although it was clearly mentioned but it doesn't matter. However when I installed it was not installed. It's really too bad, shame on Yahoo( I wonder if it is some trick against Yahoo). Anybody has an idea? I also ran HijackThis, there was some error while scanning with this, however whatever it scanned I analyzed but two automated analyzers on web and they found nothing. The results were almost same as these were few days back when I did it without spywares on my system, however I did not analyze in detail, may be some error or I missed something. About the Removal of these spywares I did not check much as I know all scanners will claim that they have removed these components but I am not so expert to check it whether they have actually done it 100% or not. I weill just clean the spywares by SuperAntispyware free edition and will do a new scan by SpySweeper to see what is left over there and will post the result. After that I will RollBack to my clean system. Below I will post some snapshots of different scanners. At the end I will emphasize again that these are no tests just a bit play as I wanted to see practically how these scanners play on my system There is no offence against any product as well. Also the results can be quite different on ur machine. I got a few malware links only. If anybody has some spyware/ trojan download links, pls PM me. Thanks and pls give ur opinions as well.
