Skip to comments.Possible Computer Virus (Need Advice)
Posted on 02/25/2012 9:46:12 PM PST by fieldmarshaldj
I've had more and more difficulties with accessing webpages (serious slowdown and pages freezing up) along with rapid bumping-off of being logged in to different websites (such as IMDb, eBay, etc.), for which I should be permanently logged in (or at least in eBay's case, for 24 hours). I go through maybe 5-10 pages or less and I get inexplicably knocked off. Again, it's not localized to just a few websites, but across the board. This computer is less than 2 years old, doesn't have a lot of memory used (or junk cluttering the system).
I have Kaspersky anti-virus and ran a scan, but it shows no viruses. I did a defrag and it was no help, and also a checkdisk scan at start-up, and that also did nothing to improve the situation.
Any ideas as to what is wrong with my computer ? I am stumped. Thanks.
Something is eating up process time or you are having big time memory problems is all I can think of right now.
Did you run Kaspersky *TDSSKiller* free and stand alone to make sure you didn't have any *rootkit* type of virus messing with the registry, these are very nasty.
For me (around2003) a Malwarebytes scan is about 3 hours.
Superantispyware is a little over 4 hours.
The processor on here is listed as AMD Athlon (tm) II P-320 Dual Core. Memory is shown as 241gb free out of 286gb. Other than their usual anti-virus, I don’t recall having run the TDSS Killer. I can try running that when this is done, but I have no idea how long this program is going to take (now at 2hrs, 45min — and still showing no objects detected).
It is taking anywhere from 1-4 seconds scanning literally every little background jpg. or whatnot on any given webpage. Unless I’m mistaken (and I do not profess to be a computer expert), there has got to be upwards of a million or perhaps tens of millions of possible individual items that may be in the system, and with having only looked at 84,000 in 2 hrs and 50 minutes, this scan could take days.
Dang, my old clunker Gateway must be really screaming, LOL.
When I run Malby, I have nothing else running, not even screen saver.
2 1/2 hours is normal for a full scan on C drive 32 Gb.
I don't usually scan the other partitioned drives on the primary drive or the secondary hard drive.
I figure if something is going to get you, it's going to get you on C.
On my wife's Win 7 machine, I scan the whole computer, both the primary SSD and the secondary hard drive because it just flies through it so fast, 45 minutes for everything.
What OS are you running? How much memory (RAM) do you have on your system?
I use a combination of AVG (free antivirus; excellent) and Malwarebytes; both can be obtained for free at www.download.com.
If you’re running Windows 7, you’d better have a bare minimum of 4GB of memory. Don’t even think about ever using IE. Use either Firefox or Chrome as your browser. Ensure your Windows updates are completely current, and......
Do what 90% of people or better NEVER do: keep your virus and malware definitions current. Such software can only protect you from what they know exist.
You may also consider running your first scans with those packages with the system booted up in Safe mode. Good luck.
It’s running so slowly, I was able to copy by hand one particular scanned file...
C:\Users\DJ\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low\Content.IE5\U3Y3LOF8\imp.css
I mean, what is this junk ?
I think that's referring to disk space available on your hard drive.
The memory I'm talking about should be from 2Gb to 8Gb on a new machine, it's basically random access memory (on memory chips) so the computer is not dependent heavily on the disk page file (slow) system,(this is a basic, basic explanation). I would also recommend that you close all windows, Internet, games, etc. etc. and let Malwarebytes run by itself. Think that's how they recommend running it.
Installed memory: 3.00 GB (2.74 GB usable).
After your scan, run Task Manager and click on the Memory Tab to see which process are eating up your memory.
After that, try downloading and running FireFox to see of there is problem with your IE9.
Also, as a precaution, download HWMonitor to check your CPU temperatures. Your machine should be idling between 28C-42C depending on the cooler and CPU.
You could very easily have a CPU that is running hot because of hardened heat sink grease and that would really slow your system down as the CPU gets hotter..
That sounds adequate to me.
I would still shut down all windows except for Malwarebytes and see if things speed up.
Just read post 50 and having HWMonitor installed is a great idea to see what your processor temps are running, things go to crap as you approach 100 C.
I have it installed on the new machine and it's a handy monitor to make sure things are running cool, especially with laptops and their marginal cooling to start with.
If you boot into safe mode and do not see a performance issue, then it is not a hardware problem.
BTW, I went back and reread you have a AMD processor, so your idle CPU temps will most likely be 36C-48C. Hardware Monitor is a free and good tool that lets me know when I need to blow the dust out of my systems plus I have had to reseat a CPU on another system with new heatsink grease about a year ago.
Cyver Tech Help has helped me several times. It is a forum type site and you simply start a thread that describes the problem. A volunteer will respond and walk you through the fix.
They will have you d/l different tool to run and then post logs that they can analyze to discover the cause of the problem, then run tools to fix them.
If your machine is as slow as it seems to be and you have access to another one, you can d/l the program to a flash drive.
Since they are volunteers there, you don't get instant response. I will take a few days to resolve the problem; but they will get to the bottom of it.
RE: Kaspersky: On the recommendation of FReepers, I junked it and loaded Microsoft Security Essentials. I got an immediate performance boost. Just for giggles, maybe disable Kas and see what she do.
Have you checked your task manager to see what is using up your resources? I once accidentally downloaded a program that installed with a ancillary program that ran continuously in the background to “monitor” my web usage. It was also using about 80 percent of my processing and slowed everything else I was doing to a crawl. I deleted the program and things got back to normal.
No idea what is causing your problem, but after reading the thread responses up to 55, another thing you could check is your hard drive and your Windows settings. You can run something like Disk Doctor to check and fix hard drive problems and Win Fix to reregister your Windows components. I use a free download program called Advanced System Care (There is a paid upgrade available, as well) that has brought old PCs back from the near dead and significantly helped several others.
I finally removed all that pathetic junk from all my computers and went to Microsoft download center to down load Security Essentials. It did not cost me a dime, it loaded fast and is designed and built for Microsoft OS’s. It works very well with XP, 7, etc, and especially with the new version of 7 and the Beta version of 8.
Forget about Fire Fox, etc,,, E8 & E9 work much better than those wannabees with Security Essentials. You can also do scans really fast, they do not load up your system, and you will enjoy much faster downloads as well as, be able to navigate faster. When it updates itself, you cannot even tell it is there either. And it does not bog down your system when it does.
Security Essentials also gives you a first class version of the program free of charge and they do not give you a skeleton version like most of the others do until you pay through the nose for their so called “professional version”.
Another point is, I have never felt more secure, and if I am assaulted by an attempt, I am immediately warned and it deals with the threat very effectively. And I have never had to “quarantine” a threat because the program could not get rid of it.
Security Essentials is one of the finest computer products I have ever used, because it really, really works. I suggest you try that first, before you use all those incompatible wannabee products that some are trying to convince you to use.
OK, the Malwarebytes ran for 7 1/2 hours and located a single virus, “PUM.hijack.startmenu”. It stated it removed it, but there are some other procedures I’m going to follow up on later (after I get some sleep !), starting with the TDSSKiller. I’ll let you all know how it goes. Thanks for the help.
I don't think 3.0 GB of RAM is enough any more, not with Win7. Right now, this computer is running Firefox and Outlook, with Kaspersky running in the background and is using 2.45 GB of RAM.
If you can, upgrade to a min of 4 GB, preferably 8 GB. More is better. Going from 2 GB to 4 GB fixed that same problem on my old Dell laptop when I switched it from XP to Win7.
Have you checked your performance score? It would be interesting to see what it says.
Also? You might find a program like Auslogics BoostSpeed helpful, as they contain all sorts of speed enhancers, registry cleaners, defragers, etc., all in one package.
Good advice. I use malwarebytes and Avast. Have no problems whatsoever.
