Since installing Malwarebytes about 2 months ago, I have been completely malware free, until today. I initially noticed the slowdown after I had adobe flash open for about 8 hours on my laptop. I only say that to provide a temporal reference to my discovery, not because i suspect flash doing something fishy with my computer. Anyways, the reason i know something's gone wrong is when i see my firefox opening new tabs on its own that are directed to no purposeful website in particular. Naturally I ran malwarebytes, and found one trojan.vundo which i took care of shortly after. The following is the log from that scan: Malwarebytes' Anti-Malware 1.33 Database version: 1654 Windows 5.1.2600 Service Pack 2 2009-02-24 12:17:24 AM mbam-log-2009-02-24 (00-17-24).txt Scan type: Quick Scan Objects scanned: 14984 Time elapsed: 2 minute(s), 25 second(s) Memory Processes Infected: 0 Memory Modules Infected: 0 Registry Keys Infected: 0 Registry Values Infected: 0 Registry Data Items Infected: 0 Folders Infected: 0 Files Infected: 1 Memory Processes Infected: (No malicious items detected) Memory Modules Infected: (No malicious items detected) Registry Keys Infected: (No malicious items detected) Registry Values Infected: (No malicious items detected) Registry Data Items Infected: (No malicious items detected) Folders Infected: (No malicious items detected) Files Infected: C:\WINDOWS\system32\wvUlkIby.dll (Trojan.Vundo) -> Quarantined and deleted successfully. Afterward I ran the scan couple more time to make sure nothing else was happening. I was thanking malwarebytes and god at this point for saving my laptop again. Then earlier today, I open firefox to check my gmail. But something is weird because access gmail takes never this long, and after 2 good minutes of trying, gmail gave up and redirected me to "sorry" splash page claiming it was receiving requests from what seemed like a virus or a spyware. I tried to access some of the other popular websites like yahoo or google and found out this spyware was interfering with my access to certain websites. Of course, this has happened before and last time it happened it was the result of the vundo virus. I ran vundofix.exe, which solved my problem last time, but it told me i was clean. I just ran malwarebytes again and spybot s&d only to find i have no infection. Gmail is still painstakingly slow. My memory usage for a blank page in firefox shoots up to 70-80 (normally it's 40ish), although it uses less than 15% of CPU. Any hints? If nothing seems obvious, i will post the hijack log.
